Kit contents

This replacement battery kit contains four 12V 7A sealed lead-acid batteries fused together into a single cartridge. It is designed as a direct replacement for the APC RBC25 pack used in the SU1400RMXLB3U rack-mount UPS.

When to replace

Swap the pack when the UPS reports a battery fault, runtime drops below what the load requires, or the existing cells reach the end of their service life. The kit restores the original 1400 VA runtime rating without changing the UPS electronics.

Installation fit

The cartridge slides into the existing battery compartment of the 3U rack-mount chassis and connects with the original wiring harness. Included instructions guide the replacement procedure, and the fused pack eliminates the need to wire individual cells.

Questions about this item

Will the 24 lb kit fit the SU1400RMXLB3U rack-mount chassis?

The four 12 V 7 A batteries are fused together as a single cartridge that matches the original RBC25 form factor for the SU1400RMXLB3U.

What is the installation step users often miss when swapping the cartridge?

Reconnect the internal battery connector and reset the UPS battery-replacement date so the monitoring firmware tracks the new 12 V 7 A set correctly.

How often should the 12 V 7 A SLA pack be replaced in continuous service?

Plan on a three-to-five-year cycle; the high-rate-discharge cells degrade faster under constant float charge than standard standby batteries.
