What is a Ni-Cd Rechargeable Battery?

NiCd batteries have been around since the late 1800s, but did not become popular until the 1980s. They are one of the most common rechargeable batteries on the market. Although they have a few negative characteristics, NiCd are efficient batteries for common uses. 

Ni-Cd rechargeable batteries are batteries that are used to power products such as electric razors, power tools and two way radios. They are one of the most used rechargeable batteries on the market. Ni-Cd batteries are made of nickel oxide hydroxide and metallic cadmium. They use nickel and cadmium as its electrodes. The Ni-Cd battery was first made in Sweden 1899 by Waldmar Junger. The battery began to be produced by the United States in the mid 1940s.

Ni-Cd batteries, although reasonable priced, cost more than lead based batteries. The rechargeable battery charges quickly and has more charging cycles than most batteries. It can have more than a 1,000 charging cycles if taken care of properly. The battery charges better at lower temperatures, which suits anyone who is constantly on the go in cold weather.

Despite its many benefits, Ni-Cd batteries have a few drawbacks. They are made with toxic metals, which are not safe for the environment. These batteries cannot be disposed of in a landfill. The battery stores less energy than other batteries, such as lithium polymer batteries, and they are subject to “memory effect.” This means that the battery cannot reach maximum charge if it has been improperly discharged.
