PowerStar 12V 55AH SLA AGM UPS battery

Suits UPS and mobility replacements.

This battery fits UPS units, wheelchairs and mobility equipment that require a 12V 55AH 22NF form factor. It also replaces dozens of listed part numbers from brands such as APC, Exide and Interstate. Buyers needing a larger amp-hour rating or a different voltage should look at other options.

55AH capacity at 12V decides fit

The single specification that determines compatibility is the 55AH capacity at 12 volts in the 22NF case size. Verify that your device specifies this exact rating and physical envelope before purchasing.

Questions about this item

Will the 9.0 x 5.4 x 8.1 inch case fit the battery tray in my UPS?

The battery measures 9.0 inches long, 5.4 inches wide and 8.1 inches high. Compare those dimensions with your UPS tray before ordering.

Can I keep my existing 50 Ah battery and use this 55 Ah unit as a spare?

Yes. The 55 Ah capacity simply provides longer runtime; it is electrically compatible with chargers designed for 50 Ah 12 V SLA packs.

How do I confirm the battery is delivering its rated capacity after installation?

Run a controlled load test at the UPS rated current and verify the backup time matches the 55 Ah specification.
