Compatible Replacement for APC BK650EI

This two-pack supplies 12 V lead-acid cartridges built to fit the APC BK650EI uninterruptible power supply. Each unit is guaranteed 100 % compatible with the original equipment so the UPS recognises the batteries immediately. The pack restores full backup capacity without modification.

Upgrade from worn or failed original cells

Replace the factory batteries when runtime has dropped or the UPS reports a battery fault. The jump is worth it when the existing set no longer holds enough charge to bridge short outages. Buyers needing higher capacity or a different voltage should look elsewhere.

Questions about this item

Will the 12V cartridge fit inside the APC BK650EI UPS chassis?

The cartridge is built to the original dimensions for the BK650EI, so it slides into the battery compartment without modification.

What is the correct sequence for installing the two cartridges?

Power off the UPS, disconnect the AC cord, open the battery door, unplug the old cartridge, connect the new red lead to red terminal and black lead to black terminal, close the door, then restore AC power.
