The problem is that the battery ages very quickly if kept at "high" temperature (20-25C) and high charge (over 80%) or depleted charge (typically under 3V). Increasing the number of charging-discharging cycles doesn't harm if charge is kept in a favorable range, say 10-70%; but currently, the controllers embedded in batteries are unable to do that properly.

Details in Wikipedia "Lithium-ion battery - Guidelines for prolonging life"

For smaller devices (e.g. PDAs, SmartPhones, Media Players), also see "Lithium-ion polymer battery"

It is even necessary if the battery walks to verify very well at first with a voltmeter if current whom she goes out with the input of the battery

I thought laptop batteries where just a bunch of rechargeable AA's? I thought I saw something like thi son metacafe once.

I wonder if it's possible to download some kind of charge manager software that will keep the battery at 50% charge or automatically cycle it to preserve the battery?
