Direct replacement for APC Back UPS BK280B

This two-pack of 12 V lead-acid cartridges is built to fit the APC Back UPS BK280B without modification. Each unit is verified for 100 % compatibility with the original equipment and carries a one-year replacement warranty. The pair restores runtime in a single swap.

Upgrade when runtime has fallen below usable levels

Replace the original cells once the UPS can no longer hold a charge through typical outages. The jump is worth it when battery tests report capacity below 100 % or the unit shuts down before 24 minutes of backup. Builders needing a different form factor or voltage should look elsewhere.

Questions about this item

Does the cartridge match the BK280B battery bay dimensions?

The cartridge is built to the original BK280B form factor, so it slides straight into the compartment without adapters.

What is the common wiring mistake when fitting the two batteries?

Connecting the red lead to the black terminal reverses polarity; always match red to red and black to black on each 12V block.
