12 V 18 Ah SLA battery for UPS replacement

This 12 V 18 Ah sealed lead-acid battery uses AGM technology and T3 nut-and-bolt terminals. It is built as a direct OEM replacement for the ZB-12-22 and compatible UPS units. The maintenance-free design suits standby power, security panels, exit signs and mobility devices.

Check voltage, capacity

Verify that your equipment requires a 12 V block rated at 18 Ah and accepts T3 bolt terminals. Confirm the physical envelope of 7.13 in length, 3.00 in width and 6.6 in height fits the battery compartment. Cross-reference the replacement list to ensure your current model appears among the supported part numbers.

Designed for standby and cyclic use over years

AGM construction delivers a 4–7 year expected life in float service and handles repeated deep cycles in scooters or wheelchairs. The sealed case prevents electrolyte loss during prolonged discharge, so capacity remains stable across long backup events. A 2-year warranty covers non-UPS applications and a 3-year warranty covers UPS and backup devices.
