12 Volt – 18 Amp Hour Battery

Sealed Lead-Acid, Maintenance-Free

The Gruber 12V 18Ah AGM battery is a sealed, maintenance-free lead-acid battery engineered
for dependable standby and light cyclic applications. Its 12-volt, 18 amp-hour capacity provides a solid power reserve
for small to mid-sized UPS systems, security and fire panels, emergency lighting, mobility devices, and OEM equipment
that require long service life and consistent performance.

Using a low-calcium lead alloy and micro-porous AGM separator, this battery delivers excellent energy density with
minimal gassing and water loss. A rugged ABS resin case keeps cells under internal pressure to resist external shock and
impact, while brass-coated lead alloy terminals minimize internal impedance for better high-rate discharge capability.
Epoxy-sealed cases and UL-certified venting support internal oxygen recombination and safe pressure relief, ensuring the
electrolyte remains fully available for electrochemical reactions but never spills.

Key Features

• 12V, 18Ah sealed AGM design — maintenance-free, non-spillable power for a wide variety of DC backup applications.
• Low-calcium lead alloy grids minimize gassing, reduce water loss, and extend grid and battery life.
• High energy density plates — cured and tank-formed active material provides stable capacity and improved cycle performance.
• Brass-coated lead alloy terminals reduce internal impedance between cells for stronger high-rate discharge performance.
• ABS resin case with internal pressure design protects cells from shock, vibration, and handling damage.
• Micro-porous AGM separator completely absorbs and retains electrolyte, ensuring it supports all electrochemical reactions without spilling.
• Epoxy-sealed case & vented cells prevent atmospheric contamination and facilitate internal oxygen recombination for longer life.
• Minimal gas evolution — reduces water loss and extends service life; UL-certified venting safely releases excess pressure and gas.

This Gruber 12V 18Ah AGM battery is a robust, drop-in replacement for many standard 12-volt SLA packs,
offering reliable power, extended service life, and safe, maintenance-free operation in demanding standby and
backup power applications.
