Understanding Your Exit Light Battery

Exit lights typically use rechargeable batteries, and depending on the model, these may last between 2 to 5 years. Knowing the specifics of your exit light battery is essential for testing it accurately. Most exit lights are equipped with either nickel-cadmium (NiCad) or lithium-ion batteries, each with distinct characteristics that affect performance.

Why Perform Regular Battery Tests?

Regular battery testing serves several purposes. It helps to:

• Prevent Emergencies: Testing the battery helps identify issues before they become critical, ensuring exit lights work properly during emergencies.
• Maintain Compliance: Many regulations require exit lights to function correctly at all times, and regular testing can help you remain compliant.
• Extend Lifespan: Identifying battery issues early can help in taking measures to replace or recharge the battery, extending the overall lifespan of your exit light.

Steps to Test Your Exit Light Battery

Testing your exit light battery is a straightforward process. Here’s how you can do it effectively:

Step 1: Gather Necessary Tools

Before starting, ensure you have the following items:

• Flashlight (for inspection in dimly lit areas)
• Multimeter (to check battery voltage)
• Replacement battery (if needed)

Step 2: Visual Inspection

Begin with a visual inspection of the exit light. Look for any signs of damage, such as:

• Cracks on the housing
• Discoloration or corrosion on battery terminals
• Loose connections

If you notice any significant damage, it might be time to replace the entire unit.

Step 3: Conduct a Battery Test

Once the visual inspection is complete, it’s time for a battery test:

1. Disconnect the Battery: Safely disconnect the battery from the unit, taking note of the wiring configuration.
2. Use a Multimeter: Set the multimeter to the DC voltage setting to measure the battery voltage. Place the probes on the battery terminals (positive to positive, negative to negative).
3. Check Voltage Levels: Compare the reading to the battery voltage specifications. A fully charged battery should read close to the rated voltage. If it reads significantly lower, the battery may need charging or replacement.

Step 4: Test the Exit Light Functionality

After testing the battery voltage, reassemble everything and conduct a functionality test:

• Activate the test button on the exit light (if available) to see if the light turns on.
• In case there is no test button, simulate a power outage by turning off the electricity to the unit for a short period.
• The light should illuminate, confirming that the battery and the light fixture are working properly.

When to Replace Your Exit Light Battery

If your testing reveals that the battery is no longer holding a charge or does not meet the voltage requirements, it’s time to replace it. Make sure to choose a suitable replacement battery compatible with your specific exit light model.

Conclusion

Regular maintenance and testing of your exit light battery is crucial for ensuring safety in emergencies. By following these simple steps, you can keep your exit lights functioning effectively and provide peace of mind in your space.
