We get a lot of questions about netbook batteries here at the Help Desk.
Your battery has a lifespan, and it will eventually need to be replaced. There's a lot of misinformation out there about batteries; if you go to ten different websites, you may get ten different types of advice.
The main thing is to develop good habits to extend the life of your battery. From our research, there are really four basic things you can do to for a battery like the one in your netbook. TL Sunny has the information:
Just to sum up...
1. Don't let your battery go all the way down to zero on a regular basis. Use it until it gets down to about 25%; then charge it up to 100%.
2. When your battery meter starts to get inaccurate, then go ahead and run it down to zero. Don't do this more than once a month.
3. Avoid heat! Heat will reduce the life of your battery. Don't leave your netbook in a car on a hot summer day.
4. If you're going to store your netbook over the summer, you can extend the life of the battery by running it down to about 40% and storing it in the fridge. For real!
