FAQ for Emergency Light Battery

  • How important is emergency lighting?
  • An emergency light is a battery-supported lighting device which will switch on automatically when in power blackouts. It’s easy to find emergency lights at commercial buildings, tunnels, and subway stations. A battery-backed emergency lighting offers illumination enabling people to move carefully to the nearest exit when in an accident.
  • How do emergency bulbs work?
  • An emergency bulb is a kind of LED lighting with built-in batteries. They’re normally wired to the power supply for continuous charging of batteries, then to provide backup power for the bulb. In the event of a power outage, the emergency lights powered by batteries keep alight for people.
  • Do emergency lights use batteries?
  • Definitely yes. A self contained emergency light is designed to work for illumination when there’s no power supply. Thus an emergency light requires a rechargeable battery to power the light when in power outages. Lead-acid batteries, NiCad batteries as well as lithium batteries are commonly found in emergency lighting.
  • How to charge an emergency light battery?
  • Charging emergency light batteries is not as hard as you may think. What is needed for charging emergency light batteries is a proper charger, the voltage of which must fit the voltage of the battery, usually is 4V, 6V or 12V. A charger with a lower or higher voltage than the batteries is forbidden to be used to charge the battery.
  • Do emergency lights have to be on their own circuit?
  • No, emergency lighting doesn’t need to be on its own circuit, but does need to be connected to the primary circuit so as to turn on if needed. Most emergency lighting is normally powered by batteries, such as SLA batteries or lithium batteries, so they only have a single circuit to operate. Emergency power delivery takes many forms, ranging from drawing power from another circuit, to battery backup systems, to outside power generators.
  • How often should emergency lighting be replaced?
  • The lifespan of emergency lights is determined by the battery powering the lighting. And a battery-operated emergency light needs to be left to run for at least 3 hours on its battery every year, any that can’t last the minimum amount of time should be replaced immediately. It’s necessary to check emergency light battery annually.
