Schumacher Electric 25A Smart Battery Charger and Maintainer - 12V DC-DC - Standard, AGM, Gel, Calcium & Lithium Battery Charger - Use with Smart Alternators for Off-Grid Power

Reliable power generated by your vehicle’s alternator can power your next adventure.

Campers, RV enthusiasts, and off-grid pioneers appreciate a source of energy to power life’s necessities.

An auxiliary or backup battery system can run lights and household appliances.

The Schumacher Electric SDC370 25-Amp 12-Volt DC-DC Intelligent Battery Charger Maintainer makes charging your auxiliary battery as simple as driving to your destination.

Smart alternators in vehicles today often make it difficult to keep your backup battery charged.

These “smart” alternators are designed to shut off when your vehicle’s starter or primary battery is fully charged.

The SDC370 solves this difficulty by boosting your alternator’s output to fully charge both your primary and auxiliary batteries.

Additionally, the SDC370 provides a steady current, instead of the fluctuating current usually provided by a modern alternator.

The SDC370 can be installed anywhere in your vehicle, such as the engine compartment, chassis rail, or passenger cabin.

Intelligent three-stage charging allows the SDC370 to charge your auxiliary battery safely and fully.

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.

Whether you're looking for a 12volt battery charger for standard batteries, or a 12v lithium charger, gel battery charger, or AGM battery charger 12v; the SDC370 will serve you well.
