S-12550: AGM VRLA Batteries

54Ah (8 Hr. Rate) to 59Ah (20 Hr. Rate) 12 Volt Battery

The sealed construction of the S-series battery allows trouble-free, safe operation in any position. There is no need to add electrolyte since gases generated during charging are recombined in a unique “Oxygen Cycle.”

The S-Series is a premier, general duty sealed lead-acid battery using absorbent glass mat (AGM) technology to suspend electrolyte in a leak-proof, maintenance-free design.
