Nickel-cadmium Rechargeable Batteries
From Wikipedia, the free encyclopedia
The nickel-cadmium battery (commonly abbreviated NiCd or NiCad) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes.
The abbreviation NiCad is a registered trademark of SAFT Corporation, although this brand name is commonly used to describe all nickel-cadmium batteries. On the other hand, the abbreviation NiCd is derived from the chemical symbols of nickel (Ni) and cadmium (Cd), though it is not to be confused with a chemical formula.
All of the rechargeable batteries on BeGreenWithSolar.com are NiCd rechargeable batteries. They can be used as solar light batteries, or in any application that uses AA batteries. Their statistics are listed below:
