Battery

In computer science, a battery refers to a rechargeable or non-rechargeable energy storage device that supplies power to electronic devices, such as laptops, smartphones, tablets, and other portable technology. It stores electrical energy in chemical form and converts it into electrical energy when required. Batteries are crucial for providing mobility and convenience, allowing devices to operate without being plugged into a direct power source. The capacity and performance of a battery are often measured in milliampere-hours (mAh) or watt-hours (Wh), indicating how much charge it can hold and how long it can power a device under specific conditions. Various battery technologies exist, including lithium-ion, nickel-metal hydride, and lead-acid, each with unique characteristics in terms of energy density, charge cycles, and thermal stability. In a broader context, battery management systems (BMS) are often used to monitor and optimize battery performance, ensuring safe operation and longevity.
