Compatible replacement for APC Back UPS Pro

This two-pack supplies 12 V, 42 Ah lead-acid cartridges built to match the original equipment specification for the APC Back UPS Pro BP650IPNP. Each unit is guaranteed 100 % compatible and carries a one-year replacement warranty. The set restores backup power for connected servers and network gear when the original cells wear out.

Capacity and headroom for typical loads

The 42 Ah rating per battery provides enough reserve for routine outages on a 650 VA UPS supporting modest server or networking loads. Runtime shortens as the connected load approaches the UPS rated capacity, and the pair cannot extend backup beyond the UPS design limits. Buyers needing longer runtime or higher VA support will require a larger UPS system.

Questions about this item

Will the 12 V 42 Ah cartridges fit the existing battery compartment in my BP650IPNP without modification?

Yes, the pack is built as a direct Cartridge #4 replacement for the BP650IPNP, so the physical dimensions and terminal layout match the original bay exactly.

How can I verify the new batteries are delivering the rated 42 Ah capacity after installation?

Run a self-test from the UPS front panel or management software; a healthy pack will hold the 650 VA load for the expected runtime and report a passed battery check.
