12 Volt – 12 Amp Hour Battery

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

The Gruber 12V 12Ah AGM battery is a sealed, maintenance-free lead-acid battery designed for
reliable standby and light cyclic applications. With a 12-volt, 12 amp-hour capacity in a compact package,
it’s an excellent choice for security and fire alarm systems, emergency lighting, small to mid-sized UPS units,
medical devices, mobility equipment, and other OEM backup applications that demand long life and consistent performance.

Built on a low-calcium lead alloy grid and a micro-porous AGM separator, this battery delivers outstanding
energy density with very little gassing and water loss. A rugged ABS resin case keeps cells under internal pressure
to protect them from external shock and impact, while brass-coated lead alloy terminals minimize internal
impedance for strong high-rate discharge capability. The case is epoxy-sealed and each cell incorporates UL-certified
venting to support internal oxygen recombination and safely relieve excess pressure — ensuring the electrolyte
supports electrochemical reactions but never spills.

Key Features

• 12V, 12Ah sealed AGM design — maintenance-free, non-spillable standby power for a wide range of DC loads.
• Low-calcium lead alloy grids minimize gassing, reduce water loss, and extend grid and overall battery life.
• High energy density plates — unique active material recipes, curing, and tank formation ensure consistent performance and quality.
• Brass-coated lead alloy terminals reduce internal impedance between cells for improved high-rate discharge performance.
• ABS resin case with internal pressure design protects from shock, vibration, and handling damage.
• Micro-porous AGM separator completely absorbs and retains electrolyte, so it supports electrochemical reactions but never spills.
• Epoxy-sealed case & vented cells prevent atmospheric contamination and support internal oxygen recombination for longer life.
• Very low gas evolution minimizes water loss, extending service life; UL-certified vent design safely releases excess pressure and gas.

This Gruber 12V 12Ah AGM battery is a robust drop-in replacement for many standard 12-volt SLA packs,
offering dependable power, extended service life, and safe, maintenance-free operation in demanding standby
and backup power applications.
