It's rather unfortunate that many laptops still do this to their batteries. The last time I bought one I made sure it has a smart charging feature: It charges the battery to a configurable upper level, then stops charging until the battery has dropped to another configurable lower level. Defaults are at 80% and 20%. Also, the discharge takes a very, very long time when plugged in, as it feeds directly from the power supply.
