ABC Series Battery Charger

The ABC 12-6 charger produces 3 step output (bulk, absorption, and float) to 2 isolated battery banks providing fast recovery and ideal cell conditioning which maximizes battery performance and life. Its rugged heat sink case utilizes convection rather than forced air cooling, thus dust and moisture are not introduced inside the unit making it ideal for vehicles which have an intermittent demand for battery power.

(For battery systems which require high continuous output, see our Phase Three Chargers)
