Many users learn little about laptop battery maintenance. As a result, the battery life of their laptop decreases sharply. One of my friends learned this hard way. He left his brand new laptop constantly charge for an entire month ignoring the smell of burning plastic and the heat coming from the laptop. Maybe if it started smoking he probably still wouldn't have unplugged the laptop battery because he would have thought that's how it must work. After this incident, he knew that he shouldn't even leave his laptop charging over night. When he sees that the battery is full, that is the time that he should unplug it. That is just one maintenance tip to protect your laptop battery. And here, we will talk about the main maintenance tips about laptop batteries.
