This is perhaps a little more complicated to swap out, but should be possible as most emergency lights are designed for this to happen. No light at all! If there was no light when there was the power cut, then check the lamp or LED’s. If the emergency light is still a fluorescent lamp then you should change it to a LED version.
Several factors can lead to battery failure in emergency exit lights: Over time, all batteries degrade and lose their ability to hold a charge. This natural aging process reduces the battery’s capacity, eventually leading to failure. Most batteries used in exit lights need replacement every 3-5 years.
Addressing battery-related issues involves regular maintenance and using the correct type of battery for your exit lights. Here are some solutions: Implement a schedule for regular battery testing to ensure they are functioning correctly. Use the test button on your exit lights monthly to check the battery’s performance.
No light at all! If there was no light when there was the power cut, then check the lamp or LED’s. If the emergency light is still a fluorescent lamp then you should change it to a LED version. You will not be able to get a replacement fluorescent lamp and LED emergency lighting has been common place for many years.
If there was some light, even briefly, then the lamp or LED’s and battery must be connected correctly. In this case it is probably the battery that either hasn’t been charging correctly or the battery itself is not holding any charge. Another way to check this is when the power is normal, was the green charge LED indicator illuminated?
An inconsistent power supply can cause the batteries to discharge prematurely or fail to charge properly. This issue can result from unstable electrical sources, poor-quality wiring, or faulty electrical components. Inconsistent power can also lead to the lights not illuminating correctly during an emergency.
