A battery is a device that stores electrical energy and converts it into a form that can be used to power electronic devices . Batteries typically consist of one or more electrochemical cells, which convert chemical energy into electrical energy through a process called electrolysis. The most common type of batteries are primary batteries, which are used once and then discarded, and rechargeable batteries, which can be used multiple times by recharging them. Batteries can be found in many different forms such as AAA, AA, C, D and 9V. They also come in different chemistry such as Lithium-ion, Nickel-cadmium, Nickel-metal-hydride and Lead-acid. The capacity of a battery is measured in milliampere-hours (mAh) or ampere-hours (Ah), which indicates how much energy a battery can store. The voltage of a battery is measured in volts (V), which indicates the amount of electrical potential energy a battery can provide. Batteries come in a wide range of types and ratings Voltage rating : This is ...
