Battery Technologies

· Rechargeable batteries in portable lighting devices and two-way radios are principally made using Nickel Cadmium (NiCad), Nickel Metal Hydride (NiMH) or Lithium Ion. (Li-Ion) technologies. Rechargeable flashlight batteries found in lights made in the past several years are generally Lithium Ion.

Each type of rechargeable battery type has unique properties:

NiCad and NiMH

· The main difference between the two is the fact that NiMH batteries (the newer of the two technologies) offer higher energy densities than NiCads. NiMH delivers approximately twice the capacity of its NiCad counterpart. What this translates into is increased run-time from the battery
