Replacement battery for APC SU1400RMX93

This 12 V lead-acid cartridge replaces the original RBC8 unit in the APC SU1400RMX93 uninterruptible power supply. The pack contains two batteries so the UPS can be restored to full runtime without mixing old and new cells. It is built for server-room and network-rack environments that rely on continuous power protection.

Practical limits of the lead-acid chemistry

Capacity drops noticeably after three to five years of float service, so plan a replacement cycle before runtime falls below critical loads. The batteries must be recycled through an approved lead-acid collection point; they cannot be discarded in general waste. No user-serviceable components exist inside the sealed cartridge.

Questions about this item

Should I choose the 2 pack or a single cartridge for my SU1400RMX93?

The SU1400RMX93 requires two 12 V cartridges; the 2 pack replaces both at once and restores the original 1400 VA runtime.

What does the 1400 VA rating mean once the batteries are installed?

It indicates the UPS can supply up to 1400 VA of apparent power to connected equipment during an outage, limited by the 12 V lead acid cartridges.
