  • Advanced AGM technology delivers maintenance-free operation
  • 12 V 55 Ah capacity powers UPS and mobility equipment
  • Direct replacement for NP55-12, GPL-12520 and HZB12-55 models
  • Compact 9.0 × 5.4 × 8.1 inch footprint fits standard 22NF trays
  • Expected 4–7 year service life with three-year UPS warranty

Direct UPS replacement

The BatteryJack 12V 55AH SLA AGM battery serves as a direct replacement for UPS units and backup devices requiring a 22NF form factor. It uses advanced AGM technology and arrives ready to install with included terminal screws. The sealed design eliminates routine maintenance and suits both standby power and mobility applications.

Fits 22NF compartments

Physical dimensions are 9.0 by 5.4 by 8.1 inches, matching the standard 22NF footprint so the battery slides into existing trays without modification. Terminal hardware is supplied, removing the need to source separate fasteners. The AGM construction allows operation in any orientation, freeing layout choices inside the enclosure.

Suits standby and mobility needs

Buyers maintaining UPS systems, wheelchairs or similar 12V 55AH equipment will find a compatible drop-in unit backed by a two-year warranty on non-UPS devices. Those requiring a different voltage, capacity or form factor should look elsewhere, as will users needing lithium chemistry or a higher cycle-life rating than AGM provides.

Questions about this item

How long does the 55 Ah AGM battery last before capacity drops off?

The manufacturer rates the expected battery life at 4 to 7 years under normal float service.

Does the sealed AGM case get hot or vent gas during a full-day UPS discharge?

The maintenance-free AGM design recombines gases internally and runs without venting or noticeable heat rise during extended discharge.

Will the included terminal screws fit the F2 tabs on my existing UPS harness?

The battery uses standard F2 faston tabs and the package supplies the matching screws for a direct bolt-on connection.
