Ademco 25404 Compatible Battery

The RefurbUPS 25404 is a new 6V 4.5Ah sealed lead-acid battery built as a direct replacement for Ademco 25404 security system cartridges. It arrives as a single T1/F1 terminal unit ready for installation in compatible alarm panels.

Capacity and headroom

The 4.5Ah rating supplies the standby current that security panels demand during mains outages, keeping sensors and communicators active for the rated discharge period. It is not suited for cyclic deep-discharge applications or higher-capacity UPS units that require larger ampere-hour reserves.

Questions about this item

Will the 25404 battery fit the same terminals as the original T1/F1 unit in my older panel?

The 25404 is a T1/F1 type, so its terminal layout matches the original Ademco 25404 battery used in legacy security panels.

How can I verify the 25404 is delivering the rated 4.5 Ah after installation?

Measure the panel's backup runtime during a mains outage; a healthy 6 V 4.5 Ah SLA should sustain the rated load for the duration specified by the panel manufacturer.
