The Schumacher DSR131 is a wheeled, heavy-duty battery charger and jump starter that provides 250A starting power for 12V systems, versatile multi-stage charging, and built-in mobility for workshops and fleet use.

Built for technicians, fleet managers, and serious DIYers, the DSR131 combines a high-output engine start function with intelligent charging and maintenance modes. It supports both 6V and 12V batteries, offers a 50-amp boost for deeply discharged batteries, and sits on durable casters so you can move reliable charging power around a busy garage or shop.

How much starting power does this charger deliver?

The DSR131 gives you commercial-level cranking and boost options to handle both passenger vehicles and larger engines. It supplies 250 amps for 12V jump starts and 125 amps for 6V systems, plus a 50-amp boost mode to revive batteries that are deeply discharged.

• 250A engine start for 12V batteries
• 125A engine start for 6V batteries
• 50A boost mode for rapid recovery
• Heavy-duty copper clamps and 6-gauge output cables

How does the automatic charging and maintenance work?

An internal microprocessor manages multi-stage charging and switches to float/maintenance when appropriate, so batteries receive the right current profile without constant monitoring. Modes include higher-rate charging and a lower-rate maintenance setting to keep batteries healthy between uses.

• Fully automatic multi-stage charging adjusts amperage as needed
• 6A charge mode for standard charge cycles
• 2A maintain/float mode for long-term battery upkeep
• Compatible with standard, AGM, gel, and deep-cycle batteries
