Charge-on-the-fly Technology

Alternator chargers boost your trolling batteries while on the water. They take excess power from the outboard’s alternator and deliver it to your trolling batteries to extend run times, decrease on-shore charge times and increase battery life.

Battery Protection

Frequent deep discharges can damage your battery over time. With the boost you get from an Alternator charger, you avoid those deep discharges – in addition to shortening charge times and extending battery life.

LED Display

LED indicators display power-on, charging and check connection.

Waterproof Construction

All of our on-board chargers are built tough, with waterproof, shock-resistant and vibration-resistant rugged construction. Plus, they’re saltwater-tested to fully combat corrosion.

3-Year Replacement Warranty

We stand behind every on-board battery charger with a full three-year replacement warranty.
