Alkaline batteries are the advanced form of Leclanche cells. Alkaline manganese battery or cell is a galvanic element and is considered one of the most important electrochemical energy device.
Due to longer shelf life, higher capacity and better durability alkaline batteries has replaced zinc carbon batteries in many applications. Alkaline batteries are primary batteries i.e. Non-rechargeable batteries.

Many portable applications such as digital cameras, GPS, remote controls, watches, measuring system, toys, flashlights, medical devices, gaming remote and many other portable applications uses alkaline batteries. All these devices requires a boast current initially and as replacement later whereas discharge profile for all the devices is can be varied.
