<human>:  How do I maintain the battery on my laptop?
<bot>: To maintain the battery on your laptop, it is important to keep the laptop charged between 40 and 80 percent, as charging all the way to 100 percent can reduce the battery's lifespan. It is best to use the charger that came with your laptop, as other chargers may not be as efficient. Additionally, you should avoid exposing your laptop to extreme temperatures as this can damage the battery. To ensure your laptop battery lasts as long as possible, it is important to regularly shut down and unplug your laptop when it is not in use.
