Middle Atlantic UPX-RPLBATT-A UPS Replacement Battery Pack
Overview
The Middle Atlantic UPX-RPLBATT-A is a 36V 7AH replacement battery pack designed to restore runtime capacity to compatible Middle Atlantic UPS units when the original battery has reached end of service life. Using a genuine replacement rather than a third-party alternative ensures the battery management circuitry in the UPS communicates correctly with the pack — off-brand cells can trigger false charge states or suppress low-battery warnings, creating exactly the gap in protection you installed the UPS to avoid. Replacing the UPX-RPLBATT-A on schedule keeps runtime specifications accurate and runtime behavior predictable in rack-based AV, security, and network deployments.
Compatibility
The UPX-RPLBATT-A is a factory replacement for Middle Atlantic UPS units in the UPX series. Verify your specific UPS model number against Middle Atlantic's compatibility documentation before ordering — UPS battery packs are voltage- and chemistry-matched to a specific chassis, and installing a mismatched pack will not function correctly regardless of physical fit. If you are unsure which battery your UPS requires, check the label on the existing pack or consult your UPS model's installation guide.
Installation Notes
Battery replacement in Middle Atlantic UPS units is typically a tool-free swap accessed from the front panel, but confirm the procedure in your UPS model's user guide before beginning — some configurations require partial rack disassembly. Disconnect the UPS from load and AC input, allow the unit to discharge briefly, then follow the documented connector sequence to avoid arc risk on the high-current DC terminals. Dispose of the spent pack in compliance with local regulations for sealed lead-acid batteries — this chemistry is not suitable for standard waste streams.
