12V 18Ah AGM Battery

This sealed lead-acid battery uses advanced AGM technology for maintenance-free operation. It serves as a direct OEM replacement for uninterruptible power supplies, alarm panels, emergency lighting and mobility scooters. The 18Ah capacity supports deep-cycle discharge in backup and standby roles.

Sustained Backup Performance

The deep-cycle design delivers steady current over long discharge periods rather than short high-current bursts. AGM construction minimises self-discharge so the pack holds charge during extended storage. Expected service life reaches four to seven years in typical float applications.

Verify Terminals and Dimensions

Confirm your device accepts nut-and-bolt terminals and that the 7.13 by 3.00 by 6.6 inch case fits the battery compartment. Check that the existing pack is rated for 12 volts and a similar amp-hour value before ordering. Weight is 12.5 lbs.

Questions about this item

How much heat does the 12V 18AH SLA battery generate when running continuously in a UPS?

Sealed lead-acid AGM chemistry produces minimal heat during normal float or discharge cycles; the battery stays near ambient temperature in a ventilated UPS enclosure.

What terminal hardware must I already have to install the SLA1116 in my UPS?

The battery ships with nut-and-bolt terminals, so you only need a compatible UPS battery tray and the existing wiring harness that matches the 7.13 in × 3.00 in × 6.6 in footprint.

Will the 18AH capacity work alongside the 15AH or 17AH batteries currently in my security panel?

Mixing capacities in the same string is not recommended; replace the whole set with matching 18AH units to keep charge balance and avoid premature aging.
