Compatible APC PS250 Replacement

This two-pack supplies 6 V lead-acid cartridges built for the APC PS250 uninterruptible power supply. Each unit matches the original form factor so the UPS recognises it immediately. The pack suits administrators who maintain several PS250 units and want a single spare kit.

Simple front-access swap

Installation requires opening the UPS front panel, disconnecting the old cartridge and sliding the new one into the same rails. No tools are needed beyond a screwdriver for the panel screws. The only common issue is forgetting to tighten the terminal bolts, which can cause an open-circuit alarm on startup.

Questions about this item

How can I verify the PowerWarehouse 2XRBC18SLA181 batteries are working after installing them in my APC PS250?

After installation, power on the UPS and check that the status indicator shows normal operation without a battery fault warning; the unit should hold a charge and support connected equipment during a brief power loss test.

What comes in the box with the 2XRBC18SLA181 2-pack and what must I buy separately for the APC PS250?

The package includes two 6 V lead-acid battery cartridges labelled #18; no extra cables or hardware are required for the APC PS250 swap.
