Do I need to charge Sunco’s LED Exit Sign built in battery?

Yes, the included battery for your LED Exit Sign may not be fully charged. After electricity is connected to the unit, the included battery needs 24 hours to charge before performing tests or using it as an emergency light during a power failure.

The Exit Sign should be hardwired to your building’s electricity so that the emergency mode will activate (and use the battery) in case of a power outage.
