OptiMate PRO-S initializes, desulfates & charges 1 x 12V battery at a time – from small

to large. The OptiMate Pro-S has a charging system able to save a neglected *sulfated

battery that cannot accept charge from a standard charger or the engine charging system.

Battery power is optimized during bulk, absorption & cell balancing charge modes, and then

tested to verify charge retention. Battery life is extended if left connected to OptiMate

PRO-S when vehicle/craft/equipment is not in use.
