Powering today’s technology

Many consumer products on the market today tout their lithium batteries as a selling feature. Is this an actual selling point? Are lithium-powered products really better than those that run on other battery types? The short answer to both questions is, yes, lithium batteries offer major advantages over other battery types with very few drawbacks. Here, we’ll look at the advantages and disadvantages of lithium batteries, as well as examine a few types of products that have been improved by incorporating lithium technology.

What is a lithium battery?

Basically, a lithium battery is one that uses lithium ions as a key component of its electrochemistry. In a lithium battery, lithium atoms are ionized and separated from their electrons. The lithium ions then move from the anode through an electrolyte until they reach a cathode, where they reassemble with their electrons.

Higher energy density

One of the greatest advantages of lithium batteries is that they have much higher energy density than other rechargeable battery technologies. Energy density is the amount of energy stored in a given volume or weight, and it’s usually expressed as Wh/kg (watt hours per kilogram). Lithium ion batteries in use today have the highest energy density of any battery technology, usually ranging from 100-265 Wh/kg.[1] Some of the newest lithium EV batteries in development have an even higher energy density of up to 315 Wh/kg and can recharge up to 80% in just 10 minutes.[2] In comparison, lead acid batteries have an energy density ranging from 30-50 Wh/kg, Ni-Cd batteries boast an energy density of 45-80 , and Ni-MH batteries have an energy density of 60-120 Wh/kg.[3]

Lighter and more compact

Due to their higher energy density, lithium ion batteries are lighter and more compact than other battery types. In fact, they make much of today’s technology feasible. Imagine if smartphones weighed 10 lbs. (4.5 kg) instead of the 6.07 oz. (172 g) weight of the iPhone 14.[4] Would they be as ubiquitous as they are now? Without small, lightweight lithium batteries everyone’s life would look very different. So, if you’ve ever slipped a battery-powered device into a pocket, purse, backpack, or glove box, this was largely made possible by the development of lithium ion batteries.

Ideal for high-power applications

Lithium ion battery technology is also advantageous for high-power applications, where a battery needs to deliver large amounts of current, such as jump starting a vehicle. Lithium ion batteries deliver up to 3.6 volts, which in comparison is three times higher than the voltage delivered by Ni-Cd or Ni-MH batteries.[5]

Recharge faster and hold a charge longer

If you want a device that will recharge quickly and hold a charge for months or years, then look for one powered by a lithium battery. The chemistry of lithium ion batteries allows them to accept current at a faster rate, allowing them to charge much faster than other battery types.[6] For example, charging a lead acid battery might take more than 10 hours where, depending on the battery’s size, a lithium battery can recharge in three hours or even a few minutes.

All battery types will lose charge or self-discharge over time. However, lithium ion batteries have an extremely low discharge rate of only 1.5% to 2% a month. In comparison, lead acid batteries lose about 5% of their charge in a month and nickel-based batteries will lose 10% to 15% of their charge in the first 24 hours and then 10% to 15% a month after that.[7] Practically, this means that if you charge a lithium battery pack and then store it in a drawer for the next year, at the end of the year the battery pack will retain between 76% and 82% of its full charge.

Increased lifespan

Battery lifespans can vary greatly although all batteries will degrade over time and lose effectiveness as they age. Usually measured by battery cycles, lifespans or cycle life are the number of complete charges and discharges a battery can experience before it will no longer hold a charge.[8] Therefore, discharging a battery to 50% and then recharging it to 100% would only count as half of a battery cycle. For example, consider a boat battery. If you compare an SLA battery (a type of lead acid battery often used in boats) to a lithium iron phosphate (LiFePO4) battery you will get a greatly different total number of charge cycles. The difference in chemistry between the SLA and LiFePO4 battery will result in the SLA battery lasting between 50 and 500 cycles, while the LiFePO4 battery will last from 1,000 to 10,000 cycles.[9]  Many affordable lithium ion batteries used in consumer products ranging from flashlights to speakers will deliver at least 300 to 500 full discharge/charge cycles before the battery’s capacity drops below 80%.[10]

Also extending the lifespan in lithium batteries is the lack of memory effect. Nickel-based rechargeable batteries, for example, will gradually lose their capacity to store energy if they are only partially discharged. The “memory” of the partial discharge reduces the capacity of future chargers and thus negatively impacts battery lifespan.

Lithium batteries also hold the advantage for depth of discharge, which is the percentage of the battery charge that can be safely drained without causing damage to the battery.[11] Lithium batteries can be safely discharged of 85% of their total capacity, while lead acid batteries can’t be discharged past 50% without negatively impacting the battery’s lifespan.[12]

All these factors combined can easily give a lithium battery a lifespan of 10-15 years vs. 3 to 12 years for a lead acid battery.[13]

Disadvantages of lithium batteries

Despite all the advantages lithium batteries possess, they do have a couple of significant drawbacks, namely the increased fire risk and their greater cost.

Because lithium batteries simply contain more energy, they also have more energy to release when something goes wrong. In fact, the higher a battery’s energy density, the more dangerous it has the potential to be.

One of the largest risks of lithium ion batteries is their susceptibility to thermal runaway. In thermal runaway the lithium battery begins an uncontrollable self-heating state, which can result in extremely high temperatures, fire, and even explosion.[14] Depending on a lithium battery’s chemistry, some are more dangerous than others. For example, lithium iron phosphate (LiFePO4) batteries are less likely to overheat than other lithium battery chemistries.[15]

Compounding the threat posed by a thermal runaway reaction, the liquid electrolytes used in lithium batteries are highly volatile and increase the risk of fire. That’s why most lithium batteries include built-in safety features and self-imposed limits on just how energy dense they can be.

The other major drawback to lithium batteries is a higher up-front cost than lead acid and other battery types. However, the cost advantages for other battery types can disappear when usage patterns and battery lifespans are factored in

It’s time to switch to lithium batteries

Lead acid batteries were first developed in 1859 and have enjoyed more than 160 years of popularity since.[16] The first viable lithium ion battery was patented more than a century later in 1976.[17] Since the first lithium battery was introduced sales have taken off and lithium batteries have made themselves indispensable to our daily lives. They power our smartphones, laptops, and even our homes. In addition, each year sees improvements to their efficiency, lifespan, and safety, while seeing a decrease in their associated costs. Today’s lithium batteries are superior in almost every way to other commercially available battery types. With this in mind, why would you choose any other battery?

As the winter chill fades away and spring bursts into full bloom, it’s time to dust off your outdoor motorized toys and get ready for some outdoor fun! From ATVs and personal watercraft to motorcycles and boats, your collection of recreational vehicles holds the promise of adventure and excitement. However, after a season of hibernation, it’s essential to ensure that your vehicles are in top-notch condition for optimal performance. In this blog, we’ll explore the vital role of battery chargers, battery maintainers, and jump starters in getting your marine and power sport vehicles revved up and ready for action this spring.

Assessing Battery Health: The Key to a Smooth Start

Before you can hit the trails or cruise the waves with your favorite rides this spring, it’s crucial to ensure that your vehicle’s battery is in optimal condition. Whether you’re dealing with a 6-volt battery in your child’s ride-on toy or a 12-volt battery in your ATV, a smooth start begins with a healthy battery. Here are some essential steps to assess the health of your batteries and ensure they’re ready for action.

Visual Inspection

Start by visually inspecting the battery for any signs of damage or corrosion. Look for cracks, leaks, or bulges in the battery casing, as these could indicate internal damage or electrolyte leakage. Additionally, check the battery terminals for corrosion or buildup, which can hinder electrical conductivity.

Voltage Check

Using a multimeter or voltage tester, measure the voltage of the battery to determine its health. For 6-volt batteries, any reading below 6 volts is suspect, while for 12-volt batteries, it should not read below 12 volts.[1] If the voltage falls below these levels, it may indicate a discharged or weak battery that requires charging or replacement. However, keep in mind that lead-acid battery voltage can vary based on variables such as ambient temperature and battery type.[2]

Load Testing

Perform a load test on the battery to assess its ability to deliver power under a simulated load. This test helps identify weak or failing batteries that may not hold a charge or provide sufficient power to start the vehicle. Many automotive supply stores offer load testing services, or you can invest in a battery load tester, such as the Schumacher BT-100, for home use.

Battery Age

Consider the age of the battery when assessing its health. Most lead-acid batteries outdoor recreation vehicles have a lifespan of around 3 to 5 years[3], depending on usage and maintenance. If your battery is approaching or exceeding this timeframe, it may be prone to failure and should be replaced as a preventative measure.

Electrolyte Levels

For batteries with removable caps, such as flooded lead-acid batteries, check the electrolyte levels and ensure they are within the manufacturer’s recommended range. Low electrolyte levels can lead to reduced battery performance and lifespan, so top up the electrolyte with distilled water if necessary.

Professional Inspection

If you’re unsure about the condition of your battery or if it’s exhibiting signs of failure, consider seeking a professional inspection from a certified mechanic. They can conduct a comprehensive assessment and recommend appropriate steps for repair or replacement.

By carefully assessing the health of your power sport, motorized toy, or marine battery before springing into action, you can avoid unexpected breakdowns and enjoy uninterrupted fun in the great outdoors. Remember, a little preventative maintenance goes a long way in ensuring a smooth start to your spring adventures!

Charging Up: The Importance of Battery Chargers

When it comes to getting ready for springtime adventures, one of the most crucial steps is ensuring that your vehicles’ batteries are fully charged and ready to go. Whether you’re charging up your children’s ride-on toys, revving up your ATV, or prepping your personal watercraft for some fun on the water, a reliable battery charger is your best friend. Here’s why regular battery charging is so important and how the right battery charger can make all the difference:

Preserving Battery Life

Batteries, whether 6-volt or 12-volt, are essential components of any motorized vehicle, and proper charging is key to preserving their lifespan. By maintaining the correct charge level and avoiding deep discharges, you can significantly extend the life of your batteries and ensure they provide reliable power season after season.

Preventing Dead Batteries

There’s little worse than eagerly anticipating a day of outdoor fun, only to find that your dirt bike won’t start due to a dead battery. Regularly charging your batteries with a dedicated battery charger helps prevent this scenario by keeping them topped up and ready for action. A good all-around battery charger to consider is the Schumacher SC1344 Wireless Fully Automatic Battery Charger and Maintainer. It features wireless monitoring and is compatible with 6-volt and 12-volt batteries.

Faster Charging Times

While some vehicles, such as children’s ride-on toys, may come with battery chargers, they often have limited charging capabilities and can take a long time to fully charge a battery. Investing in a high-quality battery charger specifically designed for 6-volt or 12-volt batteries can significantly reduce charging times, allowing you to get back to enjoying your toys more quickly. For example, Schumacher’s Charge ‘n Ride CR5 3-Amp 6-Volt/12-Volt Universal Battery Charger for Ride-on Toys charges three times faster than many included chargers.

Versatility and Compatibility

Not all battery chargers are created equal, and choosing the right charger is essential. Look for a charger that is compatible with your specific vehicles’ battery voltage or purchase a dual 6-volt/12-volt charger to accommodate the various vehicles. Additionally, opt for a charger with adjustable charging rates or multiple charging modes to suit different battery types and sizes. A good choice is the Schumacher SC1281 Fully Automatic Battery Charger and Jump Starter, which is compatible with standard, AGM, gel, and deep-cycle batteries and features fully automatic operation and an internal microprocessor that automatically detects the voltage of connected batteries and adjusts the amperage rate during charging.

Maintenance Charging

In addition to charging batteries from a discharged state, many modern battery chargers also offer maintenance or trickle charging modes, so you don’t need to purchase a separate battery maintainer. These modes deliver a low, constant charge to the battery, helping to prevent self-discharge and sulfation, which can occur when batteries sit unused for extended periods. For example, the Schumacher SC1444 Two-Bank Battery Charger and Maintainer can charge and maintain two batteries at once and employs float mode monitoring to maintain batteries after charging is complete.

Safety Features

When selecting a battery charger, prioritize safety features such as overcharge protection, short-circuit protection, and reverse polarity protection. These features help safeguard both your batteries and your vehicles against potential damage or accidents during the charging process. The Schumacher SC1319 Fully Automatic Battery Charger and Maintainer features an array of safety features designed to protect you and your vehicle.

By recognizing the importance of charging up your vehicle batteries with a reliable battery charger, you can ensure they’re always ready to go when adventure calls. Don’t let dead batteries put a damper on your springtime fun—charge up and rev up for endless hours of outdoor excitement!

Maintaining Power: The Role of Battery Maintainers

Battery maintainers play a crucial role in keeping your vehicles’ batteries healthy and ready for action, especially during periods of storage or infrequent use.

We can come to the rescue if she has a roadside emergency, recharge her tablet before book club, and power all her tailgating accessories during a Saturday soccer game.

Your Mom Can Be Her Own Hero

A dead battery can happen to anyone, but for moms it can be especially challenging. Imagine a mom you know with a car full of kids. Then, when she tries to turn on the vehicle, she finds a dead battery. Maybe it’s a hot day or the kids are especially cranky. Or maybe the mom you’re picturing is older and alone in an unsafe location. In these situations, it’s not always practical to wait for a tow truck or a good Samaritan to come to the rescue.

It’s easy to give moms the power to provide their own rescue. Simply gift them a Schumacher SL1648 1250A Rugged Lithium Jump Starter and Portable Power Pack this Mother’s Day. This jump starter features a compact size that fits in most center consoles and glove boxes, along with 1250 amps of jump starting power suitable for up to 6.0L gas and 3.0L diesel engines. It’s easy to use and also features a USB port to charge devices like a cranky toddler’s tablet. With this jump starter, mom will have the peace of mind of knowing a dead battery won’t slow her down for long.

Another option for on-the-go moms is the CRAFTSMAN CMXCESM256 Portable Power Station and 1200 Peak Amp Jump Starter. With this tool, Mom can tackle a range of emergencies and emerge victorious. In addition to a powerful jump starter, the unit also serves as a portable power station, letting mom power a range of devices including smartphones, tablets, and power tools with the 12V DC port, 120V AC household outlet with 200W inverter, and four-port USB hub. Mom can also defeat a flat tire or a deflated beach ball with the built-in 100-PSI automatic air compressor.

With either of these handy tools, mom will be prepared for any roadside emergency that comes her way.

Take Mom’s Seat on the Sidelines Up a Notch

For moms with active children, weekends are often spent on the sidelines cheering their offspring on to victory (or at least a participation trophy). This doesn’t have to mean an uncomfortable camp chair under a blazing hot sun in the summer or shivering from a cold north wind in the winter. With a little help from Schumacher, you can help the moms in your life elevate their tailgating prowess and make their children’s athletic activities something to look forward to.

Compact and lightweight, the Schumacher SL1638 Lithium Ion Portable Power Pack and 800A 12V Jump Starter will make any basketball, football, baseball, or soccer game more comfortable and a lot more fun.

Mom will be able to make it through an all-day tournament with ease.

Moms Don’t Stop When the Sun Goes Down

Unlike solar panels and sundials, mothers don’t quit working when it gets dark. They are still busy, helping with homework, cooking dinner, or shuttling kids between ballet and karate. While moms have tons of superpowers, seeing in the dark isn’t one of them. So, give a mom in your life a little help with the gift of a handy portable area light. The Schumacher SL923 LED Rechargeable Work Light is compact and powerful, easily able to illuminate any area where mom needs to boost the ambient lighting. It’s perfect for emergencies, such as helping complete Timmy’s class project during a power outage or shining a light on the hijinks of Susie’s backyard camp out. And for those times when mom’s smartphone is almost out of juice, the SL923 has a discrete USB output on the back capable of restoring a full charge.

Mom, the Green Warrior

Many moms are becoming green warriors to ensure their children will have a sustainable future. Whether this means solar panels on the roof, organic local produce in the refrigerator, or an electric vehicle in the garage, these moms are committed to saving the planet.

A busy mom will put many miles on the odometer as she runs from ballet lessons to soccer practice to the grocery store. With an EV, a busy Saturday of errands and children’s activities mean mom may have to add a charge to her car while attending a birthday party or while sitting on the sidelines at a soccer game. With the Schumacher SC1455 Level 1 and Level 2 Portable EV Charger, mom can fill up almost anywhere. She can plug her EV into any 120V AC household outlet or 240V NEMA 6-20P outlet and charge up before she heads to her next destination.

The Power of Thank You

Unlike superheroes, moms rarely get accolades or blockbuster films based on their adventures. They don’t have huge fan bases or cosplayers dedicated to replicating the outfit they wore to their last parent-teacher conference. However, you can show the moms close to you that their fan bases, while small, are devoted. This Mother’s Day give her something that will make her life a little easier, give her peace of mind, and show her just how much she is appreciated.

Since it’s National Car Care Month, I got to thinking about automotive maintenance and the many mistakes I made as a car owner in my teens and twenties. When I was a new driver, my parents ensured I knew the basics of auto maintenance. I learned how to change a tire, how to jump a battery, and even how to change my oil. But if you’re like me you never learned anything about routine battery maintenance. For most of my life, I assumed that my battery was a maintenance-free component of my vehicle. My car either started or it didn’t. If it didn’t start, I either needed a jump start or a completely new battery. That was the complete extent of my battery knowledge.

In the years since, I’ve learned that proper battery care involves more than just also making sure you turn your headlights off when you turn off your ignition. Here are 13 steps for easy battery maintenance.

1. Clean the battery terminals

Dirty or corroded battery terminals are a leading cause of battery failure. Corrosion can hamper power flow from your automotive battery. In extreme cases, it can be extreme enough to prevent the battery from providing enough power to start your vehicle. Corrosion can also cause the terminals to overheat, which can cause damage to the battery and battery cables.

To clean your battery terminals, start by identifying the positive and negative terminals. Completely disconnect the battery, starting with the negative terminal followed by the positive terminal and making sure that neither of the battery cables touch metal during the process. Make a mixture of equal parts baking soda and water. Apply the mixture with a hard-bristle brush to both battery terminals. When finished, wipe the terminals down with a wet rag, removing all the baking soda and water mixture. Then wipe with a dry cloth. Reconnect the battery cables, starting with the positive terminal.

2. Use terminal spray to prevent future corrosion

An easy way to help prevent the buildup of dirt and corrosion on your battery terminals is to use a battery terminal spray. After cleaning your battery terminals as explained in step 1 and before reconnecting the battery cables, simply apply the terminal spray to both battery terminals and the terminal ends of your battery cables. Then reconnect the battery cables.

3. Make sure the battery and cables are tightly secured

Too much vibration can damage batteries and battery cables. Make sure everything is tightly secured to prevent this from happening.

Start by opening the hood and carefully shake the battery. If there is no movement, you’re finished. If the battery moves, then your battery hold-down is probably loose. Tighten any bolts securing the hold-down and check to see if this has eliminated all battery movement. There are a variety of different hold-downs ranging from a simple bar across the top of the battery, to a hold-down pad at the base of the battery. If this doesn’t eliminate movement in your battery or if your hold-down is damaged, replace the hold-down.

4. Keep the battery warm

When the battery drops below the freezing point, your battery faces a host of challenges. However, it comes down to this. Your battery must work harder in winter and cold climates. One contributing factor to this is that cold temperatures reduce battery capacity, meaning that it is harder for the battery to generate the amount of energy needed to crank the engine and activate the starter motor. In fact, batteries lose about 20 percent of their capacity when the temperature is around 32°F and it gets worse the lower the temperature falls.[1]

During cold weather, your battery also recharges at a slower rate, requiring more time for the alternator to fully recharge the battery. Cold temps also equal more demand on your battery. Each accessory draws power and running your heater, defroster, or windshield wipers will increase the demand for power, which lengthens recharging time even further. Finally, when temperatures are low engine oil thickens, so your car battery must work harder to crank your engine.

One way to combat the drain cold temperatures cause, is to keep your battery warm. A battery heater is a simple way to do this. Some battery heaters are similar to a heating pad that you might use on a sore back but are instead wrapped around your battery to insulate it and heat your battery to a temperature above freezing. They generally will plug into any standard AC outlet. Other battery blankets are simply an insulated fabric that wraps around the battery.

In addition, some jump starters and battery chargers are equipped with pre-heating technology to warm your battery prior to starting or jump starting. For example, the Schumacher SL1648 Rugged Lithium 1250A Jump Starter warms the battery, making it possible to jump start even in extremely cold temperatures.

5. Check battery fluid levels

The are several common automotive battery types, including lead-acid wet cell (also known as standard lead-acid), lead-acid gel cell (or dry cell), absorbed glass mat (AGM), lithium-ion (Li-ion), and Nickel-Metal Hydride (NiMH). Of these battery types, lead-acid wet cell are the most common and the only type that will need to have its battery fluid levels checked. If you’re unsure of what type of battery you have, check the battery itself. It should be clearly labeled.

Before you get started, make sure you’re wearing gloves and protective eyewear. Then look at the labeling on the battery for any warnings or indications whether the battery can be opened and serviced. Once you confirm that your battery can be watered, check the water level in your battery. There should be just enough water to cover any exposed plates. If the plates are covered, close any caps or coverings you’ve opened, and then you’re done.

If any part of the plates are exposed, you will need to completely charge your battery before continuing. You can use a product like the Schumacher SC1280 15A 6V/12V Fully Automatic Battery Charger and Maintainer to do this. Then, add enough distilled water to completely cover the battery place but not reach the bottom of the vent. Do not over water. This can cause the battery to overflow and reduce the battery’s capacity and performance.

6. Reduce load when the vehicle is turned off

An easy way to be kind to your battery and prevent damage is to unplug devices when the car isn’t running. Leaving smartphones, GPS navigators, and other accessories plugged in can drain power, leaving you with a dead battery. It’s also a good idea to turn off headlights and interior lights when you turn off your engine. They will also drain power from the battery. Also, make sure you start your car before turning lights back on, which reduces the strain on your battery during starting.

7. Avoid short trips and drive your car regularly

Your car battery will recharge as you drive. How long it will take for a full recharge depends on a range of factors, such as the percent of charge after starting, battery health, the amperage produced by the alternator, and the number of your car’s accessory systems that are running. Short trips often don’t allow your car’s alternator enough time to fully recharge your battery. At least once a week take a 20-30 minute drive to ensure your battery is recharged.

8. Monitor your battery’s output voltage

Test your battery regularly. You can do this with a multimeter or a battery charger that has a built-in battery tester like the CRAFTSMAN CMXCESM253 100-Amp 6V/12V Fully Automatic Battery Charger and Jump Starter. Using a multimeter, connect the red (positive) lead or clamp to the battery’s positive terminal, then the black (negative) lead to the negative terminal. Set the meter to the DC volt setting and check your results. Batteries with a reading of at least 12.4 volts are sufficiently charged and should work as intended.[2] If the battery has a reading below 12.4 volts, attempt to charge the battery. If it cannot be recharged, replace the battery immediately. Alternatively, you can take your vehicle to a professional garage or service center. They have more sophisticated equipment and can quickly tell you if a battery should be replaced.

9. Use a maintainer/trickle charger for stored/unused batteries

If you use your vehicle infrequently or will be storing a vehicle, it’s a good idea to use a battery maintainer or trickle charger. The maintainer is plugged into a regular AC power outlet and delivers power when needed to keep the battery fully charged and in top condition.

If you are looking for a reliable maintainer, a good option is the Duralast 2A 6V/12V Battery Maintainer (DL-2D). The DL-2D battery maintainer is ideal for use with motorcycle, car, and marine batteries and features fully automatic operation

10. Do not overcharge your battery

Overcharging a battery will negatively impact its health and longevity. Most fully automatic battery chargers on the market today are intelligent enough to detect when your battery is fully charged and will stop feeding power to it. However, some older chargers/maintainers or manually operated units cannot detect a full battery and will keep sending power past the point where it is fully charged. To avoid this, look for a battery charger and/or maintainer that features float mode monitoring, which ensures that once a battery is fully charged that the unit will only supply power if the battery voltage drops below a certain point.

For a battery charger that employs float mode monitoring, check out the Schumacher Pro 12V Battery Charger and 80A Jump Starter (SPR1629).

11. Properly maintain your entire vehicle

Your battery is just one part of your vehicle. All your vehicle’s systems must work together for optimum performance. Routine maintenance such as regular oil changes and replacing spark plugs can have a positive impact on battery health. 

12. When buying a new battery, check the manufacture date

When it is time to replace a battery, make sure you check the date of manufacture and purchase a battery no more than one month old. You don’t want to purchase a battery that has already lost a good portion of its service life sitting on a shelf in your local auto parts store. Buy your battery at a high-volume seller that always has fresh stock and check the manufacture date on the battery before you complete your purchase.

Add battery care to your routine vehicle maintenance

Now that you know how to care for your car battery, it is easy to apply your knowledge and add battery care to your car’s regular maintenance schedule.

Warning signs of battery problems

While your battery might die abruptly, usually there are signs that it may be struggling. The following are four signs that your battery may need to be replaced soon.

1. Grinding or clicking sound when you crank the ignition

The most common reason for the rapid clicking sound when you try to start your vehicle is a bad battery. The clicking noise can be caused by the starter motor pinion gear connecting with the flywheel because your battery doesn’t have the power needed to spin the engine.[3] The first thing you should check is if your battery is still good. If it is, you can probably just jump start the battery. If the battery is bad, the problem can be eliminated by simply replacing the battery.

2. It takes longer for your engine to start

This most likely indicates a weak battery. Your battery may be reaching the end of its lifecycle or have another issue that has impacted its health. Have your battery tested and replaced if needed.

3. Headlights dim when idling and then brighten when you rev the engine

A common reason for headlights that dim during idling but brighten when the engine is revved is a low voltage supply.[4] Start by checking the battery. Are the battery terminal connections secure? If they are, check the battery to see if it needs to be replaced. Often, replacing the battery will fix the issue. However, in some cases dim headlights can indicate a problem with the alternator or your car’s charging system.

4. Your battery is old

No battery will last forever. Most automotive batteries will last for 3 to 5 years. So, if your battery is on the older side of that range it may need to be replaced.

Welcome to Schumacher Electric’s comprehensive guide on dealing with car battery woes in cold weather. As winter chill settles in, the frigid temperatures can wreak havoc on our vehicles, especially car batteries. Whether you’ve already experienced the frustration of a dead battery or want to stay proactive in preventing such issues, this blog post has got you covered. We’ll dive into the impact of cold weather on car batteries, provide step-by-step instructions for reviving a dead battery, offer tips for safeguarding your battery from the cold, recommend essential equipment to keep your battery in top shape, and more. Don’t let winter catch you off guard – read on to discover how to keep your car battery healthy and your vehicle running smoothly even in the roughest winter conditions.

Understanding the Impact of Cold Weather on Car Batteries

If it seems like every winter your car is harder to start or experiences more battery issues, you aren’t imagining things. Colder weather does negatively impact a battery’s performance, for several reasons.

  1. Heat damage – It may seem counterintuitive to blame winter battery issues on the heat, but oftentimes damage caused by high summer temperatures can reduce your battery’s lifespan. This can result in a battery that just can’t make it through the winter.
  2. Diminished Battery Capacity – To start your vehicle, your battery must provide a certain amount of energy to successfully crank the engine. In cold temperatures, this will require even more energy from your battery, making it work harder to provide the energy needed to activate the starter motor and crank the engine. And while your battery needs to provide more energy in the cold, its capacity also diminishes. In fact, when the temperature is at 32°F, your battery will lose about 20 percent of its capacity and will lose even more capacity as the temperature falls.[1]
  3. Slower Recharge Rate – In normal conditions, your car’s alternator will recharge the battery while you are driving. However, during winter or periods of low temperatures the alternator will take more time to recharge your battery, meaning a short trip may not give your battery enough time to be fully recharged.
  4. Amplified Power Requirements – When it’s cold outside it’s likely that you will use more accessories in your vehicles—windshield wipers, defrosters, heaters—which will increase the power demand on your battery, which further slows the recharge rate and lengthens the time required to fully recharge your battery.
  5. Thickened Engine Oil – Engine oil must flow smoothly through your engine in order for your car to start. When it is extremely cold outside, it thickens, which makes it harder to crank the engine and strains your battery.

Signs of a Dying Battery in Cold Weather

Now that you understand why cold weather is so tough on your battery, be on the lookout for signs that your battery is failing. It is always better to catch the problem early than to find yourself stranded in a dark parking lot with a dead battery on a cold evening.

  1. Engine cranks slowly – If while cranking your engine seems to be sluggish, this could be a sign that your battery is in trouble. It can also be a sign of more serious issues, such as a problem with your vehicle’s electrical system or a failing starter motor. So, if you experience this symptom, drive straight to a mechanic shop or auto parts store to have your battery tested and replaced if necessary.
  2. Headlights and interior lights appear dim – If you notice that your car’s headlights seem weaker or dimmer than usual, a failing battery may be to blame.
  3. The car’s electronics malfunction – Some newer vehicles will shut down non-essential functions when they detect a failing battery. So, if your radio stops working you might just need to replace your battery.
  4. A warning light comes on while driving or stays illuminated after starting – Many newer cars can detect a low battery charge and will turn on a battery light or flash a message about your battery. In older cars, you might get a more general “check engine” warning. If warning lights start to flash, don’t ignore them. Have them checked immediately.
  5. The battery appears swollen or damaged – Extreme temperatures or other damage can cause your battery to leak, swell, vent gasses, and, in extreme cases, explode. If you notice visible damage to the battery, do not drive your vehicle until the battery has been replaced.
  6. Your battery is old – Vehicle batteries have a finite lifespan, usually 3 to 5 years, although they can fail sooner or last beyond that window. If your battery is older than three years, have it tested to ensure it is up to the challenge of winter weather or if it needs to be replaced.

Reviving a Dead Battery in the Cold: Step-by-Step Guide

If you have a dead battery, the only short-term solution is to jump start the battery. To do this, you’ll need either a jump starter or a set of jumper cables and someone with a running car who is willing to give you a jump.

The easier of the two options is to use a modern jump pack. These portable lithium-powered units are compact and lightweight, so you can take them with you in a glove box, center console, or backpack. For those in colder climates, you should consider a jump starter that has a pre-heat function to warm up your battery before jump starting and one with enough power to start your vehicle in cold weather. Modern jump packs are also easy to use. While exact operating steps will vary (refer to the jump pack’s user manual), you will usually connect the clamps as directed, press a button, and then start your vehicle.

If you choose to use jumper cables, make sure you use cables with a low AWG (American Wire Gauge) number as these will conduct energy more efficiently, especially in cold weather.

  1. Position the two vehicles close enough that your cables can reach the battery in each vehicle.
  2. Turn off the ignition in both vehicles, as well as all accessories, such as headlights, radios, heaters, etc.
  3. Engage both vehicles’ emergency brakes.
  4. Raise the hood or access to the vehicle battery and locate the battery terminals. If the terminals are corroded, remove the corrosion with a wire brush.
  5. Connect the clamps as directed in your vehicle’s owner’s manual. This will usually be the red clamp to the positive terminal in both vehicles. The black clamps to the negative terminal in the donor car and to the vehicle chassis in the car that won’t start.
  6. Start the engine of the donor car first. Then crank the engine of the second vehicle.
  7. After it starts, disconnect the battery cables.
  8. Drive the car that was just started for at least 20 minutes to recharge the battery. Note: This will take longer in cold weather.

Preemptive Measures: How to Safeguard Your Battery from the Cold

While there are remedies for a dead battery, prevention is better for your battery’s health and lifespan and safer for you, the driver. Here are nine easy steps you can take to prevent a dead battery.

  1. Drive your car regularly – When your car is parked for extended periods, such as a week or longer, it can self-discharge. If you must leave your vehicle idle, using a battery maintainer will combat self-discharge and help maintain a full charge and battery health.
  2. Avoid short trips – In moderate temperatures it will take 20-30 minutes of driving at highway speeds to fully recharge your vehicle’s battery. It takes even longer in low temperatures. Short trips won’t give your battery the opportunity to fully recharge, so the next time you start your vehicle you’ll do so with a partially charged battery.
  3. Park in a garage – This is one of the easiest things to do to protect your battery from hot or cold temperatures. A garage helps your battery maintain a more moderate temperature, especially in the cold overnight hours.
  4. Choose a high-quality battery suitable to your climate – A battery with a high cold cranking amps (CCA) rating will deliver more energy to your vehicle during starting and better withstand a heavier load from accessories such as heated seats. A premium battery can also last up to twice as long as a standard flooded battery.
  5. Perform regular battery maintenance – It’s important to do a monthly visual inspection of your battery. This can identify damage or signs of battery corrosion. Corrosion will make your battery work harder, which is especially detrimental during cold weather.
  6. Test your battery – It’s a smart move, especially if you live in a climate with temperature extremes, to regularly test your battery. Most auto parts stores will test the battery for you, or you can test it yourself at home with a battery tester. If you test at home, batteries with a reading of at least 12.4 volts are sufficiently charged and should work as intended.[1] If the battery has a reading below 12.4 volts, attempt to charge the battery. If it cannot be recharged, replace the battery immediately. Regular testing, however it occurs, helps you identify potential problems before they happen.
  7. Insulate your battery – Using an insulation kit or thermal barrier will help your battery maintain a stable temperature and provide protection from extreme cold.
  8. Don’t run lights or accessories with the ignition off – Reduce the load on your battery by turning off non-essential items such as lights and car radios. Even items like phone chargers can be a drain on your battery.
  9. Use a battery charger and maintainer – Battery chargers and maintainers are ideal for vehicles that will sit unused for more than a week. Once your battery reaches a full charge, they will supply your battery with only enough power to offset its discharge rate. A good automatic charger/maintainer will keep your battery in top condition, extending its lifespan and making sure it starts on the first try.

Essential Tools and Equipment for Cold Weather Battery Maintenance
