What is meant by replace emergency light battery?

A rechargeable battery used in emergency lights is known as an emergency light battery. Large housing complexes, manufacturing facilities, and commercial buildings need exit signs and emergency lighting. The tenants of buildings are left in the dark when a problem arises. Many facility managers fail to notice when lights stop working, even though they are almost always visible. Building maintenance is essential to keeping your exit or emergency lights ready for the worst scenarios, and saving the backup battery packs is a necessary component of that task. 

Why can batteries be replaced for emergency lighting?

The emergency lighting batteries are essential because they provide the lights during a power loss, allowing staff and customers to locate fire exits and safely leave the facility. Additionally, they ensure that equipment, like fire extinguishers, is marked so that the trained staff members have the tools necessary to put out a fire and maybe stop it from spreading. 

  • You should verify the manufacturer's instructions before changing a rechargeable battery for emergency illumination because it may or may not be possible. 
  • Remove the battery compartment lid, remove the lens or exit faceplate, depending on the type of emergency lighting you have, remove the old battery, and replace it with a new battery that is compatible with the model of the emergency lighting. 
  • When taking out and putting back in sealed lead acid batteries, they must always be kept upright. You are required by law to replace emergency light battery pack every four years, even if the battery is still in good condition. 
  • The maintenance worker or electrician may think that changing your batteries is a job for them. But as you can see, it's pretty basic. It doesn't need to be installed by a licensed electrician and requires NO understanding of wiring or electricity.
  • Battery power is used to operate the emergency lights and illuminated emergency exit signs. These batteries are rechargeable to continuously maintain the emergency light's readiness and functionality. The battery is charged and maintained in a charged state by circuitry in the emergency light. 

How to test the batteries in emergency lights:

  • Making sure your batteries are functional is essential. According to the statement, a building must have sufficient lighting to escape and see firefighting tools. Every emergency light has a test button someplace on the housing. 
  • For around 30 seconds, press and hold this button, ensuring your lights don't go off or dim. You should get a professional as soon as possible to fix this if your light does fade or some of the bulbs aren't functioning correctly. This battery must be replaced every four years; however, occasionally, they don't last that long. 
  • Regular testing of the lights ensures that you can maintain the batteries effectively and maintain the illumination of evacuation locations. Every emergency lighting system needs to be examined once each month. 
  • The test should last long enough to guarantee that the luminaire performs properly while minimizing any harm to the system's parts, such as the lamps and battery. 

Significance of replacing the emergency light battery:

For an emergency light to function, batteries are required. Batteries will eventually lose their capacity to store a charge and require replacement. Knowing when to replace emergency light battery is crucial. Your emergency light might not function if the battery isn't changed if you need it most. The batteries may need to be changed every two to three years, depending on the battery type, how frequently the light is used, and other circumstances. The batteries may need to be changed more often if the light is used regularly or is exposed to harsh weather. If your emergency light isn't working, it can be because the battery is dead, so you need to buy a new one. 

How emergency do lights work?

In the event of a mains power outage, emergency lighting's job is to give enough light along the departure route to allow building occupants to do so safely. When there is a crisis, it is utilized to illuminate the area so people can leave a structure or specific location. It is a vital step in the safety of human life and is mandated by most construction codes. There are several reasons why emergency lights are essential. In an emergency, they assist in creating a safe atmosphere for occupants to leave a building and support first responders by offering direction. 

How long should a battery in an emergency light typically last, and what circumstances can shorten it?

Typically, an emergency light's battery lasts for three to four years. The following elements may bring on premature battery failure:

  • High outside temperature
  • Storing the emergency luminaires after purchasing them for an extended period before installing them.
  • Storing emergency batteries in a discharged state for a long time, such as while building
  • LiFePO4 batteries require temperatures below 0°C. 
  • Additional cost savings and aesthetic advantages come from installing emergency lighting rather than isolated batteries or emergency lighting devices. 


Checking the batteries in your emergency lights regularly is crucial. While most batteries have a life expectancy of three to five years, some may need to be changed earlier. It's time to replace emergency light battery if you discover that your emergency lights are no longer lasting as long or performing as effectively as they once did. JIEYO batteries provide a high power density and a long lifespan.
