6/12V 275A ProSeries Battery Charger/Engine Starter

ProSeries wheel charger with flash programming for shops and garages

Offering the ultimate in battery charger capabilities, the DSR122 ProSeries Battery Charger and Engine Starter is the high-performance battery charger that any garage or auto shop needs. With a maximum amperage of 275, the DSR122 can charge and start even the largest 6- and 12-volt batteries.

The DSR122 is easy to use thanks to its digital display, push-button control, and extra-long output cable with a 17-foot reach.

It is protected from temperature overload, and its heavy-duty steel case and clamps allow for rugged, outdoor use.

Equally well-suited to crank an engine or charge a battery, the DSR122 also features flash programming and can flash reprogram a battery.

  • Memory-saver mode saves vehicle settings while charging the battery
  • Multi-stage charging for added precision, safety, and battery life
