DC ALTERNATOR ON-BOARD CHARGERS

AN EXTRA JOLT

Get an extra boost of power and better battery life. Our Alternator chargers use charge-on-the-fly technology to redirect excess power from your alternator to your trolling batteries. 

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.
