Compatible with APC BR1500-FR

This 24 V lead-acid battery cartridge is built to fit the APC BR1500-FR uninterruptible power supply. The pack contains two units so the UPS can be restored to full runtime in a single swap. It is intended for server-room and network-closet administrators who need a direct replacement without sourcing original-equipment parts.

Two-cartridge pack simplifies maintenance

Supplying both required cartridges together eliminates the risk of mismatched ages or capacities inside the UPS. Installers replace the pair at once, reducing downtime and avoiding the scheduling of a second service visit. The bundle suits teams that prefer a single part number for complete battery renewal.

Expect a service life of 3-5 years under normal float charge; plan replacement around the 4-year mark for critical loads.

What is the first limit reached when the UPS runs continuously at full load?

The 24 V lead-acid pack hits voltage sag and thermal limits before the APC BR1500-FR inverter does.
