APC BP420PNP Compatible Battery Pack

This PowerWarehouse 12 V lead-acid cartridge replaces the APC BP420PNP battery in supported UPS units. The two-pack supplies both cells required for a complete swap and is guaranteed to be 100 % compatible with the original equipment.

When a Full Battery Change Is Needed

Replacing both cartridges at once restores balanced runtime and prevents the weaker cell from limiting the fresh one. The upgrade is worth it when the UPS self-test reports reduced capacity or when the existing batteries have reached the end of their service life.

  • Two-pack format lets you refresh both cells at once
  • Guaranteed 100% compatibility with APC BP420PNP units

Questions about this item

Does the 12 V cartridge match the APC BP420PNP mounting brackets?

The cartridge is built to the same 12 V form factor as the original BP420PNP, so it slides into the existing brackets without modification.

What is the correct orientation when inserting the two batteries into the UPS?

Align the terminals with the UPS connectors exactly as the old cartridge sat; reversing polarity prevents the unit from powering on.
