Maintaining Your Exit Sign Backup Battery

As a responsible owner of exit signs, it is crucial to regularly check and maintain the backup battery to ensure its optimal performance. By following these maintenance tips, you can be confident that your exit sign will always be ready for use in case of an emergency.

  1. Regular Inspections:
    • Perform visual inspections of the exit sign and backup battery at least once every three months.
    • Check for any physical damage or corrosion on the battery terminals.
    • Ensure that all connections are secure and free from loose wires.
  2. Testing Procedures:
    • Conduct monthly testing of the backup battery by simulating a power outage.
    • Activate the test switch or follow the manufacturer’s instructions to initiate a self-test mode.
    • Observe if the exit sign illuminates properly and remains lit for at least 90 minutes, as required by safety regulations.
  3. Cleaning:
    • Keep the exit sign clean from dust, dirt, or other debris that may obstruct its visibility during emergencies.
    • Use a soft cloth dampened with mild soap and water to gently wipe down both sides of the acrylic faceplate.
    • Avoid using abrasive cleaners or solvents that could damage the surface.
  4. Battery Replacement:
    • If you notice any signs of deterioration in your backup battery such as reduced illumination time or frequent failures during testing, it may be time for a replacement. Consider replacing your backup battery every two to five years depending on its type and usage.
  5. Environmental Factors:
    • Be mindful of environmental conditions that can affect your backup battery’s lifespan:
    • Extreme temperatures: High heat or freezing cold can shorten battery life significantly.
    • Humidity: Excessive moisture can cause corrosion on terminals and reduce overall performance.
    • Chemical exposure: Keep batteries away from corrosive substances as they can damage internal components.
  6. Documentation:
    • Maintain records of all maintenance activities, including testing dates and any issues encountered. This documentation will help you track the performance of your backup battery over time and ensure compliance with safety regulations.
