How long do batteries last in emergency lights?
Most self-contained battery powered emergency lights tend to last anywhere from 3-6 years before they need replacing. So you can expect to replace all your batteries, and in some cases the complete fittings every 3-6 years, hitting a peak replacement curve at the 4-5 year mark.
Can car battery die from hazard lights?

Do you need a battery for an emergency light?
BATTERIES FOR EMERGENCY LIGHT All emergency lights and lighted emergency exit signs use a battery for powering the lamps. In order to insure continuous readiness and operation of the emergency light, these batteries are rechargeable. Circuitry within the emergency light both charges the battery and insures that it stays charged.
How long does an emergency exit sign battery last?
Since each battery in the pack has its own positive and negative terminals, multiple cells are combined into one easy to connect lead. Most emergency Exit Signs are powered by a building’s AC power which keeps the battery backup system fully charged. During a power failure the battery will need to light the sign for at least 90 minutes.
Why does my emergency light not charge properly?
Too high a voltage will blow the lamps, while too low a voltage will cause the lamps to be dim. Additionally, if the battery voltage and circuit card voltage are not the same, the battery will not charge properly.

What should I do if my light bar is draining my battery?
If you’re going to use a power supply, make sure its voltage output is within the light bar’s specifications. Also, make sure it can supply the maximum current your light bar draws. Use a wire gauge that matches or exceeds the maximum current of your LED light bar.
