Gruber 12V 12 Amp Hour AGM Battery — Sealed, Maintenance-Free Standby Power

The Gruber 12V 12 Amp Hour AGM battery provides dependable energy storage for compatible standby and light cyclic applications. Its compact, sealed lead-acid design supports UPS systems, security panels, emergency lighting, instrumentation, and OEM backup equipment.

Built with Absorbent Glass Mat (AGM / VRLA) technology, the battery retains its electrolyte within micro-porous glass-mat separators. This non-spillable construction eliminates routine watering and electrolyte maintenance.

Low-calcium lead-alloy grids help minimize gassing and water loss. A rugged ABS resin case protects the internal cells, while low-resistance terminals support efficient current delivery. Epoxy-sealed construction and pressure-regulated venting support oxygen recombination and release excess internal pressure when necessary.
