APC Back-UPS Pro 420 Battery Kit

This replacement battery kit is designed for the APC Back-UPS Pro 420 UPS. It provides a factory-fresh 12V 7Ah battery cartridge to restore backup power capability. The unit is a compatible alternative to the APC RBC2 cartridge. It suits users needing a direct swap to maintain their existing UPS runtime.

Single Battery Runtime Constraint

The kit contains only one 12V battery, so total energy capacity remains limited to the original specification. Extended runtime during prolonged outages is not possible without a UPS model supporting external battery packs. Users requiring longer backup duration must consider a different UPS architecture rather than this replacement cartridge.

Questions about this item

Should I choose the single 12 V 7 Ah cartridge or look for a multi-battery kit for my Back-UPS Pro 420?

The Back-UPS Pro 420 uses only one 12 V 7 Ah cartridge, so this single-battery kit is the correct fit.

What runtime can I expect once this 12 V 7 Ah battery is installed in my Back-UPS Pro 420?

Runtime depends on the connected load; the 12 V 7 Ah cartridge restores the UPS to its original battery capacity for the same load profile.
