Two 12V 7.0Ah AGM batteries replace the APC Back-UPS XS1500 with leak-free, maintenance-free sealed construction
This 2-pack of 12V 7.0Ah sealed lead-acid batteries replaces the original cells in an APC Back-UPS XS1500. They use AGM technology for maintenance-free operation and leak-free performance in any orientation. The set is built as a 100% OEM replacement with an expected service life of four to seven years. A 24-month warranty covers the batteries.
Capacity is fixed at 7.0Ah, so runtime scales directly with the load placed on the UPS. The sealed AGM design prevents electrolyte loss but cannot be topped up, meaning the pack must be replaced once voltage drops below usable levels. Gas recombination handles over 90% of internal gassing during normal float charging. Operating the UPS outside its specified temperature range will shorten the four-to-seven-year design life.
Each battery measures 5.94in long, 2.56in wide and 3.72in high, weighing 13.16lbs. The T2 terminals accept the existing UPS connectors without adapters. Sealed construction meets IATA non-spillable classification for safe transport. The rigid ABS case fits the XS1500 battery compartment exactly, so no modification of the chassis or wiring is required during installation.

No published specifications for this item yet.
The XS1500 requires two 12V batteries wired in series; the 2-pack supplies both so the UPS returns to its 1500VA rating.
1500VA is the apparent-power limit of the UPS electronics; the real watts you can draw depend on the power factor of your connected gear.
T2 faston tabs accept the XS1500's factory connectors directly, so no adapters or soldering are needed for a secure fit.
