Compatible kit for SMX750 UPS

This replacement battery kit is built for the APC Smart-UPS X 750 LCD (SMX750). It supplies a factory-fresh cartridge containing four 12V9A cells that match the RBC116 specification. The unit weighs 28 and arrives new, ready for immediate installation in compatible UPS systems.

Replaces worn RBC116 cartridges

The kit restores runtime when the original battery pack no longer holds charge or shows degraded backup time. It is not suited for UPS models that require a different cartridge voltage, cell count or physical form factor. The upgrade is worth it when the existing pack reaches end of life and the SMX750 must stay online without a full unit replacement.

Questions about this item

Will the four 12 V 9 Ah batteries in this kit fit the existing tray of an APC Smart-UPS X 750 LCD?

Yes, the kit is built as a direct RBC116 compatible cartridge containing four 12 V 9 Ah cells that match the original dimensions and connector layout for the SMX750.

What is the most common mistake when installing this replacement battery cartridge in the SMX750?

Forgetting to reseat the Anderson-style power connectors fully; they must click into place before the front cover is closed or the UPS will not recognise the new cartridge.
