UPS Replacement Battery

The PowerStar Leisure Lift Pace Saver Burke Mobility Scout RF4 is a 12V 55Ah sealed lead-acid battery built with advanced AGM technology. It serves as a 100 percent OEM replacement for UPS systems, wheelchairs and mobility equipment. The maintenance-free design eliminates the need for electrolyte checks or water top-ups. Condition is new with a three-year warranty on UPS and backup devices.

AGM Capacity and Compatibility

The 55Ah rating provides longer runtime than older 50Ah units while fitting the same 22NF group size. Dimensions are 9.0 by 5.4 by 8.1 inches, matching standard 22NF footprints. Terminal screws are included for secure connection to existing wiring harnesses. The battery replaces a wide range of OEM part numbers across brands such as Deka, Exide, Interstate and NAPA.

When the Upgrade Is Worth It

Choose this unit when a UPS or mobility device shows reduced backup time or fails self-tests after several years of service. The higher 55Ah capacity extends run time without changing enclosures or cables. It is not suited for applications requiring lithium chemistry, higher voltage packs or cyclic deep-discharge ratings beyond standard AGM specifications.

Questions about this item

How do I know this 12V 55Ah AGM battery will fit my mobility scooter or UPS?

It matches the 22NF case size at 9.0 by 5.4 by 8.1 inches and replaces dozens of OEM part numbers including 22NF-420, NP5512 and PS1255, so it drops into the same tray and uses the included terminal screws.

What does the 55Ah rating actually deliver in daily use?

The 55 amp-hour capacity means longer run time between charges than a 50Ah pack, powering a typical mobility scooter or UPS for extended periods before recharge is needed.

Is the AGM chemistry truly maintenance-free and spill-proof in any orientation?

Yes, the sealed AGM design requires no watering, vents no gas under normal operation and can be mounted on its side or upright without leakage.
