Compatible UPS replacement battery

This AJC C4S cartridge supplies a single 6 V 4.5 A sealed lead-acid cell designed to restore runtime in compatible uninterruptible power supplies. It arrives factory fresh and includes comprehensive installation instructions so technicians can swap the spent pack without specialised tooling.

Suits administrators refreshing ageing UPS units

The kit addresses the need for a direct drop-in cell when the original battery reaches end of life. Buyers who require higher capacity, extended runtime modules or multi-cell hot-swap trays should look at larger cabinet-scale solutions instead.

Delivers 4.5 A of high-rate discharge

That rating comfortably supports typical desktop and entry-level server UPS loads during brief outages. Extended-duration demands or redundant parallel-string configurations will exceed the single-cell headroom this cartridge provides.

Questions about this item

Does this AJC C4S kit include the 6 V 4.5 A SLA cell needed for my UPS?

Yes — the package contains one factory-fresh 6 V 4.5 A high-rate-discharge sealed lead-acid battery that matches the AJC C4S specification.

Can I swap this battery into an older UPS that still uses the same cartridge form factor?

The battery is built to the AJC C4S cartridge dimensions, so it will fit any UPS model designed for that exact cartridge size and connector layout.

How do I confirm the new battery is delivering power after I install it?

Run a self-test from the UPS front panel or management software; a successful test and normal runtime indication show the 6 V 4.5 A cell is working correctly.
