Compatible UPS Replacement Battery

This UPS replacement battery kit contains one 6V 4.5Ah sealed lead-acid unit with T1/F1 terminals. It is a direct replacement for CSB GP640 battery cartridges and ships ready for immediate installation. The package includes step-by-step fitting instructions.

For single-cartridge UPS maintenance

The kit suits administrators swapping a single exhausted cartridge in compatible UPS units. It does not serve installations that require multiple batteries, higher amp-hour ratings or different terminal styles. Buyers needing extended runtime or alternative connector types should look elsewhere.

6V 4.5Ah capacity with T1/F1 terminals

The 4.5 amp-hour rating at 6 volts determines whether the cartridge matches the original UPS specification. Verify that the host unit calls for exactly this voltage and capacity and that the T1/F1 terminal layout matches the existing wiring harness.
