The leak-proof suspended-electrolyte design is maintenance-free and contains no REACH SVHC substances.

Who should order this

This cartridge suits owners of compatible APC UPS units who need to restore original runtime without powering down connected equipment. It is not for buyers who require a different VAH rating, a lithium chemistry or a battery that fits non-APC chassis.

Check before ordering

Verify that your UPS model appears in the supported list such as SUA750RMI1U, SUA1000RM1U or EMC750RM1U. Confirm the physical bay accepts a cartridge measuring 3.70 by 5.10 by 5.90 inches and weighing 10.90 lbs. Ensure your existing wiring uses the connectors supplied with this cartridge.
