What are the different types of batteries available in the market and their applications?
Batteries available in the market are usually classified as primary batteries and rechargeable batteries. Primary batteries are sometimes called “throw-away” batteries because they will be discarded when they are flat, as they cannot be recharged for reuse. Common types of primary batteries include alkaline, zinc carbon, lithium, silver oxide and zinc air batteries. Rechargeable batteries can be recharged and reused for up to 1000 times depending on usage conditions. Common types of rechargeable batteries include Nickel Metal Hydride (NiMH), Nickel Cadmium (NiCd) and Lithium Ion (Li-ion) batteries.
