The times I have removed it from the mains the battery held out for only about 10 minutes before dying.
I'm experimenting with removing the batteries completely, but ideally would like to have the battery backup in case of a power outage. My other option is to get a UPS and run without the laptop battery.
How old is your laptop? This may be a case of expectations not meeting reality. As the Wiki article linked previously mentions, LiION batteries deteriorate over time and with use (as do all batteries). In my experience, a typical laptop battery (treated well) will last 2 years while maintaining the majority of its original capacity. After 5 years, the battery run time is often inadequate to meet the needs of the owner. When purchasing a laptop, I would have the expectation that the battery will need replaced every 2-3 years - if the laptop is used, assume that it needs a new battery.
If your battery is only maintaining a run time of 10 minutes, it has reached the end of its life. If this has occurred in less than 2 years then there is a problem and I think you're going about it the right way (or perhaps via a warranty claim), but if the battery is greater than 3 years old I would have to say it's just time for a new one.
