The DSR122 is easy to use thanks to its digital display, push-button control, and extra-long output cable with a 17-foot reach. The microprocessor provides fully automatic or timer-controlled charging and works for standard, deep-cycle, AGM, and gel batteries alike. 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.
Additional features include:

• Memory-saver mode saves vehicle settings while charging the battery
• Multi-stage charging for added precision, safety, and battery life
• Float-mode monitoring maintains optimum battery charge
• Reverse hook-up protection
• One-year warranty
