The Sterling Power AB12400 is a marine-grade alternator-to-battery charger for 12V systems, rated 400A. It gives boats, RVs and work vehicles the performance of an advanced alternator regulator without the fitting work, and installs in place of a standard battery isolator.
It watches and controls the voltage on the alternator side so it can drive a proper four-step charge into your batteries, which Sterling says recovers them up to five times faster than a standard alternator. It makes sure the starter battery gets fully charged without being overcharged, and drops to float once charging is complete. For lithium house banks Sterling recommends its battery-to-battery chargers instead.
Features
- Four-step charging with float mode to prevent overcharging

- Can handle different battery types on board at the same time
- Keeps the starter battery properly charged and protected from overcharge
- Installs in place of a standard alternator-to-battery isolator
