Compatible Kit for APC SMX1500RMI2UNC

This replacement battery kit is built for the APC Smart-UPS X 1500 Rack Mount LCD unit. It supplies four 12V9A sealed lead-acid cells that match the original RBC115 specification. The kit suits administrators who need to restore runtime on an existing UPS without sourcing OEM cartridges. It is not for buyers who require a different voltage or capacity configuration.

Four 12V9A Cells Provide Standard Runtime

The pack contains four high-rate discharge batteries rated at 12 volts and 9 ampere-hours each. Together they deliver the factory-rated capacity for the SMX1500RMI2UNC, supporting typical server loads during outages. Runtime will decrease as the load approaches the UPS maximum, so the kit does not suit installations that demand extended backup beyond the original design. The total weight is 28.

Installation Instructions Included for Self-Service

Every kit ships with comprehensive replacement instructions that guide technicians through the cartridge swap. This documentation enables in-house maintenance without external service contracts. No additional tools, mounting hardware, or management software are bundled, so teams must supply any required enclosures or monitoring accessories separately.

Questions about this item

Will the 12 V 9 Ah cells fit the existing tray in my APC Smart-UPS X 1500 rack-mount unit?

The kit contains four 12 V 9 Ah batteries that match the RBC115 form factor used by the SMX1500RMI2UNC, so they slot straight into the original tray.

How can I confirm the UPS recognises the new battery kit after installation?

After fitting the four cells, run the UPS self-test from the front-panel LCD; a passed test and a green status indicator show the kit is working as intended.

Does the package include the connectors and hardware needed for the swap, or must I buy them separately?

The box supplies the four 12 V 9 Ah batteries plus comprehensive installation instructions; no extra connectors or mounting hardware are required.
