12V 55AH AGM UPS Battery

The BatteryJack 12V 55AH sealed lead-acid battery uses AGM technology for maintenance-free operation. It serves as a direct OEM replacement for the SLA1165 model and includes terminal screws for installation. The unit carries an expected service life of four to seven years under normal conditions.

Suits UPS and mobility units.

This battery fits UPS systems, wheelchairs and mobility devices that require a 22NF form factor. It replaces a long list of OEM part numbers across multiple brands. Buyers needing a different voltage, capacity or terminal layout should look at other models.

55 ampere-hours at 12 volts

The 55AH rating delivers sustained runtime for typical backup loads and mobility applications. Runtime shortens under heavy continuous discharge or extreme temperatures. The three-year warranty on UPS devices reflects the manufacturer's confidence in this capacity class.

Questions about this item

Does the 12 V 55 Ah AGM block need any extra wiring or connectors to fit a UPS that takes an SLA1165?

The battery ships with terminal screws included, and the SLA1165 designation confirms a direct 100 % OEM replacement fit.

Can the 22 NF footprint battery sit beside older 12 V 33 Ah units in the same cabinet without clearance issues?

At 9.0 by 5.4 by 8.1 inches it matches the standard 22 NF envelope, so existing brackets and ventilation spacing remain unchanged.

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

Run a full-load runtime test on the UPS; the measured backup minutes should align with the 55 Ah rating and the 4–7 year design life.
