Direct UPS Replacement

This 12 V 55 Ah sealed lead-acid battery uses AGM technology and fits the 22NF form factor. It is a maintenance-free, 100 % OEM-compatible unit designed for UPS systems, wheelchairs and mobility devices. The PowerStar brand carries a two-year warranty on backup devices. It replaces a long list of part numbers including UPS12-170 and UB12550.

Verify Voltage Form Factor Terminals

Confirm that your equipment requires a 12 V nominal voltage and accepts the 22NF case size of 9.0 by 5.4 by 8.1 inches. Check that the terminal layout matches your existing connections and that the supplied screws suit the terminal threads. Ensure the charger or UPS is calibrated for AGM chemistry and a 55 Ah capacity rating.

Higher Capacity Than 50 Ah Units

If your current battery is rated at 50 Ah, this 55 Ah model will provide longer run-time without changing the footprint. The upgrade is worthwhile when extended backup time is needed for critical loads or mobility range. It is not suited for systems locked to a lower Ah rating or for applications requiring a different voltage or case standard.

Questions about this item

Does the 12V 55AH SLA battery ship with terminal screws or must they be purchased separately?

The battery comes with screws for the terminals so no extra hardware is needed for installation.

The listing shows 22NF and 55AH — which capacity should I choose for a UPS that originally used a 50AH pack?

The 55AH 22NF unit is a direct replacement; the higher amp-hour rating will simply provide longer run-time.

What does the 55AH rating mean for actual UPS run-time once the battery is installed?

A 55AH pack delivers more stored energy than a 50AH original, so the UPS will power connected equipment for a longer period during an outage.
