Emergency lights and exit signs both require batteries. Emergency light batteries are used to operate the light when power to your building is lost during an emergency and the same is true for exit sign batteries. Both emergency light and exit sign batteries operate their respective fixtures for 90 minutes after power loss.

Most exit signs today us LEDs for illumination and utilize Nickel Cadmium batteries. Nickel Cadmium batteries, also called Ni-Cad, are small and compact, they resemble the shape of a AA battery and come shrink wrapped in different configurations. Each Ni-Cad cell is 1.2v, so a 4 cell exit sign battery would be 4.8v.

Emergency lights on the other hand, utilize more powerful batteries because they are used to power incandescent lamps, which require more electricity than LEDs found in exit signs. Sealed Lead Acid is the most popular type of emergency light battery. The top selling model is our 6 volt 4.5 amp Sealed Lead Acid emergency light battery. This battery is found in most emergency lights as well as combo exit sign that have lights attached to them.
