Troubleshooting Tips: Emergency Light Stays On After Battery Replacement

Emergency lights play a crucial role in ensuring the safety of occupants in a building during an emergency situation. These lights are designed to switch on automatically during power outages or other incidents, guiding individuals to exit safely. However, you may occasionally encounter a situation where your emergency light stays on even after you've replaced the battery. In this blog post, we'll explore some common reasons for this issue and provide troubleshooting tips to help you resolve the problem.

6 Quick Easy Steps

1. Double-check the battery installation:

First and foremost, ensure that the new battery has been installed correctly. Sometimes, improper battery installation can lead to the emergency light staying on. Verify that the battery terminals are connected securely, and the battery is seated properly in its compartment. If the issue persists, move on to the next step.

2. Examine the wiring connections:

Wiring issues can often cause emergency lights to malfunction. Inspect the wiring connections between the battery, the charging circuit, and the light itself. Look for any loose, frayed, or damaged wires. If you find any issues, make sure to repair or replace the damaged wiring. Remember that working with electrical wiring can be dangerous, so if you're not comfortable with this task, consult a professional electrician for help.

3. Reset the emergency light:

In some cases, resetting the emergency light can resolve the issue. To do this, unplug the emergency light from its power source, disconnect the battery, and wait for about 30 seconds. Reconnect the battery and plug the emergency light back into its power source. Observe if the light turns off after completing these steps.

4. Inspect the charging circuit:

If the emergency light remains on, there may be a problem with the charging circuit. The charging circuit is responsible for charging the battery when the light is not in use. If the circuit is faulty or damaged, it may cause the emergency light to stay on continuously. Inspect the charging circuit for any visible signs of damage, and if necessary, consult a professional electrician for repair or replacement.

5. Check the relay or control module:

The relay or control module is responsible for switching the emergency light on or off. A malfunctioning relay or control module can cause the light to remain on after a battery replacement. You may need to consult the user manual or contact the manufacturer for guidance on how to test the relay or control module for proper functionality.

6. Replace the light bulbs:

In some instances, the issue may be caused by the light bulbs themselves. If the bulbs are nearing the end of their lifespan or are damaged, they can cause the emergency light to stay on. Replace the light bulbs with new ones and see if this resolves the problem.


Emergency lights are essential for safety, and it's important to address any issues promptly to ensure they function correctly when needed. If your emergency light stays on after a battery replacement, try the troubleshooting tips mentioned above to identify and fix the problem. If you're unable to resolve the issue on your own, it's always a good idea to consult a professional electrician or contact the manufacturer for assistance.
