NICKEL-CADMIUM STORAGE BATTERIES
NICKEL-CADMIUM STORAGE BATTERIESAircraft nickel-cadmium storage batteries are constructed of wet cells. One advantage of the nickel-cadmium cell is that it contains a greater power-to-weight ratio than a lead-acid battery. Also, the CCV of a nickel-cadmium battery remains nearly constant during the entire discharge cycle. Nickel-cad-mium batteries are much more costly than a typical lead-acid battery and therefore are usually found on turbine-powered aircraft. The extra capacity available from a nickel-cadmium battery will help prevent a hot start of the turbine engine, and thus the extra cost is justified. Nickel-cadmium batteries are often referred to as "ni-cad" (short for nickel-cadmium) batteries.
