12 V Lead-Acid Cartridge for APC BK250B

This two-pack supplies 12 V lead-acid cartridges built to fit the APC Back UPS BK250B. Each unit is guaranteed 100 % compatible with the original equipment and carries a one-year replacement warranty. The pair restores backup runtime for the supported UPS model.

Replaces aged or failed internal batteries

Swap them when the UPS no longer holds charge through short outages or when the self-test reports a weak cell. The jump is worth it if the unit is still in service and the original cells have reached end of life. Buyers needing a different voltage, form factor or connector should look elsewhere.
