6 Volt – 12 Amp Hour – 20 WPC – Battery

Sealed Lead-Acid, Maintenance-Free

The Gruber 6V 12Ah AGM battery is a sealed, maintenance-free lead-acid battery engineered for dependable standby power and light cyclic applications. Its 6-volt, 12 amp-hour capacity delivers extended runtime in a compact footprint, making it an excellent choice for security and fire systems, emergency lighting, mobility equipment, small UPS systems, instrumentation, and OEM backup applications where consistent performance and long service life are essential.

Built with a micro-porous AGM separator and low-calcium lead alloy grids, this battery provides excellent energy density while minimizing gassing and water loss. A rugged ABS resin case helps protect the internal cells against shock and vibration, while brass-coated lead terminals reduce internal impedance for dependable high-rate discharge performance. Epoxy-sealed construction and controlled venting support internal oxygen recombination, non-spillable operation, and safe pressure relief.
