Ni MH battery is used in many applications where the life of the battery is not critical. Such examples are toys, golf carts, fork lifts, and even forklift trucks. This type of battery is a chemically engineered version of the Nickel metal hydride cell. The chemical reaction in the positive hybrid electrode is very similar to that of a nickel metal hydrate battery, using cadmium instead of nickel. But the negative cells use a different hydrogen-absorbing material instead of cadmium instead.
Overview and Benefits
This type of battery has three major advantages over NiCad batteries. The first is that it can retain its charge for a longer time period as the NiMH does not have any slow down period like the NiCad battery, which tends to power down after a certain level of charge. Secondly, the higher charge capacity of the NiMH battery allows it to perform better than other types of alkaline batteries. Finally, it has the additional advantage of being able to retain its charge for longer periods.
NiMH battery can be purchased in a few different variants. The best option will depend on your usage and the environment. If you are looking for the longest possible shelf life, then the nickel hydrogen battery would be the best option. It is available in a few different voltages, which could be useful depending on the application, but these tend to drain much faster.
