Replacement Cartridge for APC UPS Models

This sealed lead-acid cartridge replaces the APC APCRBC176 and fits the BVX1600LI, BVX1600LI-GR, BX1600MI, BX1600MI-FR and BX1600MI-GR units. It delivers 24 volts from two 12-volt 7-ampere-hour cells with F2 terminals. The pack arrives tested, charged and ready for immediate installation.

Runtime and Recharge Limits

Backup time ranges from 1 to 30 minutes depending on the connected load. A full recharge requires less than 24 hours, so the UPS cannot supply extended runtime during repeated outages. The cartridge is not suitable for applications that demand longer autonomy or faster recovery between discharge cycles.

Straightforward Swap with Polarity Care

The cartridge slides into the UPS battery compartment and connects via the existing F2 terminals. Installation is complete once the leads are attached to the correct poles; reversing the polarity will prevent operation. No tools or firmware updates are required, but buyers needing a different voltage or capacity must select another part number.

Questions about this item

Should I pick the 24V 7AH cartridge or look for a different capacity for my BX1600MI?

The cartridge supplies 24V from two 12V 7AH blocks, which is the exact voltage and capacity the BX1600MI expects, so no alternative capacity is required.

What does the 1 to 30 minute run time mean when the UPS is under load?

At light load the unit can run up to 30 minutes, while at full rated load it will last closer to 1 minute before shutdown.

Does the F2 terminal type limit which APC models I can install this cartridge in?

The F2 terminals match the original APCRBC176 design, so the cartridge fits every listed APC model without adapter cables.
