Same experience here, i kept my laptop in a socket almost every day for 2 years only bringing it out maybe once a month. The battery was as good as new until i forgot it completely uncharged for 2 weeks when it overnight reduced its 2h capability into more like 2 minutes.

Oh yeah, that kills them pretty fast. I've had the same experience with my backup cellphone and mp3 player, had to buy new batteries.

Hmm. Then maybe I'm ascribing my problem to the wrong behavior. I wonder whether I inadvertently left my problem children discharged for too long, at some point.

I've gotten reliable service out of my mobile phones, but laptop Li ion batteries continue to feel (for lack of a more consistent and rational/analytical approach, on my part) like black magic, to me.
