How can I tell when the battery in my ILBLP CP HE SD Emergency LED Driver is fully charged?

To check the charging status of your ILBLP CP HE SD Emergency LED Driver's battery, consult the TBTS (Threaded Body Test Switch) light indicator. A steady green light on the TBTS signifies that the battery is fully charged and ready for use in an emergency. If the TBTS light is a steady red, the battery is currently charging. This simple visual cue allows you to quickly assess the battery's charge level and ensure your emergency lighting system is prepared.
