Batteries and Power Supplies

Emergency batteries are used to operate a lighting unit, electrical exit sign or exit sign combo when regular normal power is lost. Both emergency light and exit sign batteries operate their respective fixtures for at least 90 minutes depending on the specification.

Backup batteries often run out. Even though some batteries are rechargable, eventually the ability to recharge stop. Speaking of exit signs, most of them use LEDs for proper illumination while utilizing nickel cadmium batteries. Nickel Cadmium batteries, also referred to as Ni-Cad, are small and compact elements that resemble the shape of a AA battery and come shrink wrapped in configurations of 2-10 cells. Each Ni-Cad cell is 1.2v, so as you add one, just simply multiply by 2. Ex: a 4 cell exit sign battery would be 4.8v (1.2 x 4 = 4.8v).

Emergency lights on the other hand, need to utilize a more powerful source. Due to the need to power lamps (incandescent), which require more electricity than the LEDs found in exit signs. Sealed Lead Acid batteries are the perferred choice for emergency lighting units.
