What is the best way to charge a laptop battery?
While other posts here are correct in saying that while the computer is plugged in it runs from the A/C and does not continue to charge the battery, this is not what causes damage to a battery. Leaving the battery plugged in all the time will decrease the overall battery life, because your laptop produces heat, temperature is a big thing and will damage a battery, it is best to pull the battery out if you are using it in one place for a long time.
