Questions about this item

Will the 12V 18A rating match the original LightAlarms unit I am replacing?

Yes, the cartridge supplies a single 12V 18A high-rate discharge SLA cell, matching the voltage and capacity specified for the OSG12E3.

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

The security panel should show a normal battery status indicator and hold its charge during a mains outage test.
