Gruber 12V 18Ah AGM Battery — Sealed, Maintenance-Free Standby Power

The Gruber 12V 18Ah AGM battery is a high-capacity, sealed lead-acid battery engineered for dependable standby power and light cyclic service. With 18 amp-hours of capacity, it provides substantial energy reserve for UPS systems, security and fire panels, emergency lighting, mobility equipment, medical devices, telecommunications equipment, and a wide range of OEM backup-power applications.

Built with advanced Absorbent Glass Mat (AGM / VRLA) technology, the electrolyte is completely absorbed within a micro-porous glass-mat separator, creating a sealed, non-spillable battery that requires no routine watering or electrolyte maintenance.

Low-calcium lead-alloy grids help minimize gassing and water loss while supporting long service life. High-density active material and low-resistance internal construction provide consistent capacity and strong discharge performance when equipment demands higher current.

A rugged ABS resin enclosure, securely sealed case construction, and pressure-regulated venting protect the internal cells while promoting oxygen recombination and safely relieving excessive internal pressure when required.
