Aside from the AA and AAA subtypes and the rechargeable vs regular, not too many people think about batteries. After all, how different are most batteries from one another? Well, there are several different types of batteries out there for people to use, and all of them have their own properties that make them special or useful for their field.
First, there is the NiCd battery or Nickel Cadmium batteries. These batteries have a long life and can produce a lot of energy, and are often used in video cameras, power tools, and as a kenwood radio battery. They are designed to last long, come at a medium price range, and expend a lot of energy with tough work environments.
NiMH batteries, or Nickel-Metal Hydride batteries are slightly less lasting of a battery in terms of power but also is much more friendly for the environment. It’s the most common type of battery and is used in computers and phones. Due to the environmental friendliness of the battery when disposed of, it has been pushed by various groups as a better alternative to the NiCd battery.
Lead acid batteries are the oldest type of battery, but are extremely light and are used in places that don’t have to worry about weight. These can include electronic wheelchairs, and hospital equipment and lighting. They provide a lot of power and don’t need to be recharged as often.
All of these batteries produce power in a different way, as lead acid batteries use lead electrodes. NiCd and NiMH batteries use metals as electrodes, and all of them have different capacities that make the battery suited for its job. Looking at each of the strengths and weaknesses of the different battery types will help you figure out what kind of battery will work the best for your device.
