Abstract:
An electrical battery is one or more electrochemical cells that convert stored chemical energy into electrical energy. Batteries are a power source for household and medical applications. Batteries are available in various sizes for use in different devices and appliances. Batteries have a shelf life for optimum use. Shelf life is often indicated on the battery. Inappropriate use or storage may cause a battery to become faulty before the lapse of shelf life. Faulty batteries must be identified and replaced. A common fault in batteries is leaking or corrosion. In this skill, you will identify the leaking or corroded batteries.
