How to Change the Battery of an Emergency Light?

Apr. 19, 2023

Emergency lights are essential in buildings, offices, and public spaces as they provide illumination during power outages and emergencies. A key component of an emergency light is its battery, which is responsible for providing power during a power outage. Over time, batteries can degrade, and their capacity can reduce, which means that they may need to be replaced. In this article, we will discuss how to change the battery of an emergency light.

Before we start, please note that the specific steps for changing the battery of an emergency light may vary depending on the make and model of the device. Always consult the owner's manual or contact the emergency lighting product manufacturer for specific instructions.

Step 1: Identify the Type of Battery

The first step in changing the emergency lighting battery is to identify the type of battery used in the device. Most emergency lights use rechargeable batteries, and the most common types of rechargeable batteries are lead-acid and nickel-cadmium (NiCad) batteries. Lead-acid batteries are heavier and larger than NiCad batteries, but they provide a longer backup time. NiCad batteries, on the other hand, are smaller and lighter, but they have a shorter backup time. Once you have identified the type of battery used in your emergency light, you can purchase a replacement battery.


Step 2: Turn Off the Power

Before you start working on the emergency light, you must turn off the power supply to the device. This is important to avoid any electrical shocks or accidents. If the emergency light is connected to the mains power supply, turn off the circuit breaker or unplug the device from the power outlet.

Step 3: Remove the Cover

The next step is to remove the cover of the emergency light. The cover is usually held in place by screws or clips. Use a screwdriver or pliers to remove the screws or press the clips to release the cover. Once the cover is removed, you should be able to access the battery compartment.

Step 4: Remove the Old Battery

Carefully remove the old battery from the battery compartment. If the battery is soldered in place, use a soldering iron to remove the connections. Be careful not to damage the battery or the battery compartment while removing the old battery.

Step 5: Install the New Battery

Insert the new battery into the battery compartment. Ensure that the positive and negative terminals of the battery are correctly aligned with the terminals in the battery compartment. If the battery is not held in place by a clamp or a bracket, use a piece of adhesive tape to secure the battery.

Step 6: Reassemble the Emergency Light

Once the new battery is in place, reassemble the emergency light. Replace the cover and secure it with screws or clips. If the battery is connected to a circuit board, reattach the wires using a soldering iron.

Step 7: Test the Emergency Light

Turn on the power supply to the emergency light and test the device. Ensure that the light turns on when the power supply is disconnected or when the test button is pressed. If the light does not turn on, check the connections and ensure that the battery is correctly installed.

In conclusion, changing the battery of an emergency light is a simple process that can be done with basic tools. However, it is important to follow the manufacturer's instructions and take necessary precautions to avoid any accidents or damage to the device. By replacing the battery when necessary, you can ensure that your emergency light is always ready to provide illumination during power outages and emergencies.
