What is a computer battery?
Your computer uses battery power when it's unplugged. It is measured in cell count and watt-hour (Wh). The higher the cell-count in your battery, the longer its battery life. But more cells also means a heavier battery and less mobility. Higher battery wattages mean your computer can be used longer without being plugged in.
Battery runtime is dependent on multiple other factors, like the intensity of the applications you use and display brightness. More intensive programs will drain the battery more quickly.
