<human>:  How does a laptop battery work?
<bot>: A laptop battery is typically a rechargeable battery which provides power to a laptop computer. It works by converting the energy stored in the battery into usable electricity to power the laptop. The energy stored in the battery is released as electrical current when it is connected to the power source. The current then passes through the laptop’s internal circuitry, powering the various components, such as the processor and hard drive. When the power is disconnected, the laptop will remain powered on until the battery is drained.
