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.
