  • 12 V 18 Ah capacity supports deep-cycle backup needs
  • Nut and bolt terminals enable secure drop-in installation
  • Expected service life of 4 to 7 years in standby use

12V 18Ah AGM battery for backup and mobility

This sealed lead-acid battery uses advanced AGM technology and delivers 12 volts with an 18 amp-hour capacity. It is a 100% OEM replacement for many UPS, fire alarm, security, exit lighting and mobility devices. The nut-and-bolt terminals simplify wiring in fixed installations. Maintenance-free operation suits set-and-forget deployments.

Maintenance-free design with no gas emission

The sealed AGM construction eliminates electrolyte spillage and requires no watering or venting in normal use. Self-discharge is low, supporting the quoted 4-7 year expected life in standby applications. No active cooling is needed, so the unit runs silently in cabinets, enclosures or under seats. Power draw is limited to the connected load and internal self-discharge only.

Fits standard 18Ah footprints

Dimensions are L-7.13 in W-3.00 in H-6.6 in and weight is 12.5 lbs, matching common 12V 15-20Ah battery compartments. The bolt terminals accept ring lugs for secure connections in vibration-prone scooters, wheelchairs or gate operators. It replaces numerous Yuasa, Power-Sonic, Panasonic and CSB part numbers without adapter brackets. Buyers needing higher capacity or different terminal styles must select another model.

Questions about this item

How do I install the nut-and-bolt terminals, and what mistake should I avoid?

Place the battery with terminals facing up, remove the protective caps, thread each bolt through the cable lug and into the terminal nut, then tighten to a firm torque; the common error is cross-threading the bolt or leaving the connection loose, which causes voltage drop and heat.

What maintenance or replacement will this 12 V 18 Ah AGM battery need over its 4-7 year design life?

The sealed AGM construction is maintenance-free — no water topping or equalisation charges are required; plan on full replacement once capacity falls below usable levels, typically after 4 to 7 years in standby service.

What is the first limit reached when this battery runs under continuous load?

The 18 Ah rating defines the total energy available; once that capacity is drawn the voltage drops sharply, ending useful output — thermal rise inside the sealed case is the next practical constraint during prolonged high-current discharge.
