SDC370
25A 12V DC-DC Intelligent Battery Charger

Charge auxiliary batteries using your vehicle’s alternator

Modern vehicles with smart alternators make it difficult to keep a backup battery charged. These “smart” alternators are designed to shut off when the vehicle’s starter or primary battery is fully charged. Schumacher’s SDC370 25A 12V DC-DC Intelligent Battery Charger solves this difficulty, boosting the alternator’s output to fully charge an auxiliary battery. In addition, the SDC370 provides a steady current, instead of the fluctuating current usually provided by a modern alternator. As an added advantage, the SDC370 can be installed anywhere in the vehicle, such as the engine compartment, chassis rail, or passenger cabin.

Built-in, three-stage charging allows the SDC370 to safely and fully charge the auxiliary battery. First, boost mode delivers maximum voltage for an initial period. Next, absorption mode supplies a continuous charge. Finally, float mode helps maintain a full battery charge by delivering a trickle of power when needed.
