Direct replacement for APC SC25ORMI1U UPS

This two-pack of 6 V lead-acid cartridges is built to fit the APC SC25ORMI1U uninterruptible power supply. Each unit carries the PowerWarehouse 2XRBC18SLA188 designation and is sold new with a one-year replacement warranty. The set restores backup runtime without modifying the UPS chassis.

Upgrade from depleted or ageing cartridges

When the original batteries no longer hold a full charge, this kit returns the UPS to its rated 25-minute runtime at typical load. It is not suited for systems that require a higher voltage string or a different form factor, and it does not add extra capacity beyond the factory specification.

Questions about this item

Will the two 6 V cartridges slot straight into the APC SC25ORMI1U without extra brackets?

Yes, the pair is built as a direct cartridge #18 replacement for that UPS model, so the existing mounting points line up with no additional hardware required.

What is the common mistake when swapping the batteries in the SC25ORMI1U?

Installers often forget to reconnect the internal series link between the two 6 V blocks, leaving the UPS with only half the required voltage.
