A laptop battery is a rechargeable device that provides power to a laptop computer when it is not connected to an electrical outlet. It is a portable power source that enables users to use their laptops for an extended period of time without the need for a direct power source.
Laptop batteries are usually made of Lithium-ion (Li-ion) or Lithium-polymer (Li-Po) cells that store energy in chemical form. They come in different sizes, shapes, and capacities to match the power requirements of different laptop models. The capacity of a laptop battery is measured in milliampere-hours (mAh) or watt-hours (Wh), which indicates how much energy it can store.
Laptop batteries are designed to be rechargeable and can be recharged using a laptop charger that is compatible with the laptop model. The charging process involves converting AC power into DC power and sending it to the battery to recharge the cells. Laptop batteries can last for several hours on a single charge, depending on factors such as the battery capacity, laptop usage, and power management settings.
Over time, laptop batteries may lose their capacity to hold a charge and may need to be replaced. Most laptop batteries are replaceable and can be purchased from laptop manufacturers or authorized service centers. It’s important to choose a battery that is compatible with the laptop model and is of good quality to ensure proper fit and performance.
