Purpose and compatibility

The PowerStar Siltron EM56 is a 12 Volt 7.5 AH sealed AGM battery designed as a direct replacement for emergency lighting units. It suits facility managers and maintenance teams who need a drop-in power source for exit signs and backup fixtures.

Build integration

The unit measures 5.94 by 2.56 by 3.66 and uses T1/T2 terminals, so it fits existing battery compartments without rewiring. Its maintenance-free construction removes the need for fluid checks and frees up service time for other safety tasks.

Thermals noise and power

Advanced AGM technology keeps internal resistance low during standby float charging, so the battery runs cool and silent in normal operation. The sealed design prevents gas release, and the 4-7 year expected life supports reliable backup power across extended duty cycles.

Questions about this item

How long will the 12 Volt 7.5 AH battery last under continuous emergency lighting load before needing replacement?

Expected battery life is 4 to 7 years under normal standby use; actual runtime during a sustained power cut depends on the fixture's current draw.

Does the sealed AGM design run hot or make noise when powering a fixture all day?

The maintenance-free AGM construction is sealed and produces no audible noise; heat output is minimal during normal float charging and emergency discharge.

What terminal type must my emergency light fixture have to accept this T1/T2 battery?

The battery uses T1/T2 terminals measuring 5.94 by 2.56 by 3.66 inches; verify your fixture's connector matches this interface before installation.
