Compatible UPS battery cartridge

This factory-fresh cartridge contains a single 12V9A unit built to fit the MK ES9-12FR form factor. It is intended for users who need a direct replacement to restore runtime in an existing UPS system. Buyers requiring a different voltage, capacity or chemistry should look elsewhere.

Sealed lead-acid construction

The sealed design operates without liquid electrolyte spills and requires no routine maintenance. Normal float charging keeps the cell ready for discharge cycles during power interruptions. No active cooling or external ventilation is required for typical indoor operation.

Questions about this item

Disconnect the UPS from mains power, open the battery compartment, unplug the old battery leads, connect the new battery observing the same polarity, then close the compartment and restore power.

Expect a service life of three to five years under normal float conditions; plan to replace the cartridge when runtime drops noticeably or the UPS signals a battery fault.
