Replacement Battery for Back-UPS Pro 420

This factory-fresh compatible battery cartridge fits the APC Back-UPS Pro 420. It contains one 12V 7A sealed lead-acid unit. The kit restores backup power to the UPS so connected equipment stays running during outages. It is intended for owners of this specific model who need a direct swap.

APC RBC2 Compatible Kit Contents

The package supplies a single 12V 7A battery that matches the original RBC2 specification. No extra cables, mounting hardware or software are included.

Questions about this item

When will the 12V 7Ah battery cartridge need replacing?

Plan to swap the cartridge every three to five years; runtime drops noticeably once the cells can no longer hold a full charge.

What runs out first during a prolonged outage with the BP420S installed?

The 12V 7Ah capacity limits total runtime, so the UPS will shut down once that stored energy is depleted.
