Gruber 12V 12Ah AGM Battery — Sealed Lead-Acid, Maintenance-Free

The Gruber 12V 12Ah AGM battery is a sealed, maintenance-free lead-acid battery engineered for dependable standby power and light cyclic applications. Its 12-volt, 12 amp-hour capacity delivers substantial backup power in a compact package, making it an excellent choice for security and fire alarm systems, emergency lighting, small to mid-sized UPS systems, medical equipment, mobility equipment, instrumentation, and OEM backup applications requiring reliable performance and long service life.

Built with low-calcium lead alloy grids and a micro-porous AGM separator, this battery delivers 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 alloy terminals reduce internal impedance for dependable high-rate discharge performance. Epoxy-sealed construction and controlled safety venting support internal oxygen recombination, non-spillable operation, and safe pressure relief for reliable, maintenance-free service.
