G-12550: Gel VRLA Battery

44Ah (8 Hr. Rate) to 50Ah (20 Hr. Rate) 12 Volt Block

The sealed construction of the SBS G-series battery allows trouble-free, safe operation in any position. There is no need to add water to the batteries since the gases generated during charging are recombined in a unique “Oxygen Cycle”. Because of this recombination effect the batteries require no maintenance other than routine testing. When ordered with a VR-series VRLA battery rack, the G-series batteries and rack come complete with all required cables to install this economical and compact system.
