  • Advanced AGM technology enables maintenance-free operation
  • 55 Ah capacity provides extended runtime for UPS and mobility devices

55 AH 12 V AGM UPS replacement battery

This 55 ampere-hour sealed lead-acid battery uses AGM construction to serve as a direct drop-in replacement for uninterruptible power supplies, mobility devices and solar storage banks. It arrives new and maintenance-free with terminal screws included for immediate installation.

22NF footprint with screw terminals

The 22NF case measures 9.0 by 5.4 by 8.1 inches and carries the same terminal layout as the original packs it replaces, so existing cable runs and battery trays fit without modification. AGM electrolyte is absorbed in glass mat, eliminating spill risk and allowing operation in any orientation.

Upgrade from 50 AH or legacy SLA packs

Installers replacing a 50 AH unit gain extra runtime without changing enclosures or wiring, while the three-year warranty on UPS applications covers the expected 4 to 7 year service life. The jump is worth it when longer backup time or a fresh maintenance-free cycle is the priority.
