12 Volt – 10 Amp Hour – 22 WPC – Battery

Sealed Lead-Acid, Maintenance-Free

The Gruber 12V 10.5Ah AGM battery is a sealed, maintenance-free lead-acid battery designed for reliable standby and light cyclic service. Its compact footprint and robust 10.5Ah capacity make it ideal for small UPS systems, security and fire panels, emergency lighting, medical and test equipment, and other OEM backup applications that demand long life and consistent performance.

Built around a micro-porous AGM separator and a low-calcium lead alloy grid, this battery delivers excellent energy density, low gassing, and spill-proof operation in any orientation (except inverted). A rugged ABS resin case holds cells under internal pressure to resist impact and vibration, while brass-coated lead terminals minimize internal impedance for better high-rate discharge capability.

Key Features

• Low-calcium lead alloy grids minimize gassing and extend grid life for longer service intervals.
• Optimized active material formulation with curing and tank formation provides outstanding energy density and consistent capacity.
• Brass-coated lead terminals reduce internal impedance and improve high-rate performance.
• ABS resin case with internal pressure design protects cells from external shock and vibration.
• AGM (Absorbed Glass Mat) separator fully absorbs and retains electrolyte for spill-proof, maintenance-free operation.
• Electrolyte volume optimized to fully support electrochemical reactions while preventing leakage.
• Epoxy-sealed case and vented cell covers protect against atmospheric contamination and support internal oxygen recombination.

This 12V 10.5Ah Gruber AGM battery is a drop-in replacement for many standard 12V SLA packs and offers dependable, long-life performance wherever compact, maintenance-free backup power is required.
