Compatible Replacement Kit for APC Smart-UPS RT 1000

This kit supplies four 12V 7A sealed lead-acid batteries designed as a direct replacement for the APC SURT1000RMXLI uninterruptible power supply. It matches the RBC31 compatible specification and is sold in new condition. The package includes installation instructions for straightforward servicing.

Verify UPS Model and Battery Bay Configuration

Confirm that your unit is the APC Smart-UPS RT 1000 with model number SURT1000RMXLI before ordering. The kit contains exactly four high-rate discharge cells, so the UPS must accept a four-battery cartridge. Check that the existing batteries are 12V 7A units and that the battery compartment matches this pack layout.

Sustained Discharge Performance for Runtime

The high-rate discharge chemistry is built to maintain voltage during extended outages rather than only brief spikes. Factory-fresh cells deliver consistent capacity across the full discharge curve, supporting reliable runtime when the UPS carries a continuous load. Steady output helps protect connected servers through longer power events.

Questions about this item

Does the kit include everything needed to replace the batteries in my SURT1000RMXLI, or must I order cables separately?

The kit supplies four 12V 7A high-rate SLA batteries that match the APC RBC31 cartridge; installation instructions are included and no extra cables are required.

Why does this replacement kit contain four 12V 7A cells instead of a different count or capacity?

The SURT1000RMXLI uses a 24 V internal bus, so four 12 V blocks wired in series provide the correct voltage and runtime for the 1000 VA unit.

What runtime can I expect from these 12V 7A batteries once installed in the 1000 VA Smart-UPS RT?

Four 12V 7A cells restore the original 24 V 7 Ah capacity, delivering the same backup time the UPS provided when it was new.
