Emergency Light Batteries
We stock NiCd, NiMH and Lithium Emergengy Light batteries for all types for lighting applications including Emergency lighting and Fire Exit signs.
The original Lighting battery packs were usually NiCd or Nickel Cadmium which is a 1.2v cell and comprises multiple cells to give 2.4V, 3.6v, 4.8v and 6v packs in various arrangements. NiMH or Nickel Metal Hydride batteries are similar to the older NiCd types and also are 1.2V in voltage with multiples of this figure making up larger packs. NiMH batteries are usually higher in capacity buy have a faster discharge rate than NiCd.
Lithium or Li-Ion batteries are 3.7V ( sometimes 3.6V) and, again, come in packs that are single 3.7V, double 7.4V or triple 11.1V. They are also refered to as 1S1P, 1S2P, 2S1P packs according to their wiring in either series or parallel to give different voltages or capacities.
