in my personal experience (family members who refuse to listen to me ), I've seen laptop batteries become useless alot sooner than they should.

Most recent example:

My uncle brought some new laptops home from work, and the kids used them basically for homework, and other light-duty uses, and left them plugged in round the clock. This went on for a year. I was at their house a couple of weeks ago and pulled the computer out to do some work at the kitchen table. I turned it on, and the battery died immediately. So I pulled out another one, and the system gives a fatal message about the health of the battery if it isnt plugged into a charger.

The theory is that a battery gets (x) amount of charge cycles in it's life. Ideally, you wanna use the entire charge amount (run the battery to 0%) before recharging, otherwise you're wasting charge cycles. So what you have is a battery that's never being unplugged, but unquestionably using battery and using charge cycles.
