Laptop battery life
Once a battery has a reduced charge life (45 min.), is it possible to build it back up by any means?
Thanks.
Thanks.

Not necessarily, Alex.
LION batteries lose about 20% of their capacity per year. Environmental conditions (the heat inside a laptop, or leaving it in a hot car) can accelerate the loss. So can deep-cycle discharges, i.e. running the battery all the way down and then recharging.
2 to 3 years and 300 or so charges are about the limit.
The way to prolong the life of a LION is to keep it at about 40% charge, remove it from the laptop when the laptop is running on AC power, and store the battery in the fridge (not the freezer).
Charge it to 100% only when you know you'll need it.
LION batteries don't have memories like NiMH and NiCD.
