The SC-6 is a 6-station HD recovery charger designed to recover, charge, maintain and desulfate from one to six 12-volt lead-acid batteries.
Besides my SUV, I’ve used trickle chargers on 12-volt lead-acid car and deep-cycle golf cart batteries. They also can be used on 12-volt lithium-ion, absorbent glass mat (AGM) and gel-cell batteries.
