Direct replacement for APC BE550GX576

This two-pack of 12 V lead-acid cartridges is built to match the original equipment in APC BE550GX576 units. Each battery carries the model identifier 1104 and is guaranteed 100 % compatible for a straight swap. The set restores full runtime to the UPS without any wiring changes.

Upgrades worn cells in the same chassis

When the original batteries no longer hold charge, this pack replaces them both at once, eliminating the mismatch risk of mixing old and new cells. The jump is worth it once runtime drops below useful levels or the UPS reports a battery fault. Buyers needing a different voltage, form factor or connector type should look elsewhere.
