It's a good idea to REMOVE the battery from a laptop that you're not going to use for a while. This keeps it from discharging and possibly damaging itself.
What happens is that even though the laptop is OFF, it still draws a little power. Over time this fully discharges the battery pack and some of the cells in the pack are a bit stronger than some of the others. This causes a REVERSE CHARGING effect on the weaker cells and destroys them. This is one of the disadvantages of LiIon type cells, they are VERY SENSITIVE to reverse charging.
There is NO WAY to recover these cells. Unlike NiCD cells which could often be "zapped" back into life, LiIon cells respond to this type of treatment by EXPLODING! Please DO NOT attempt this at all.
The only solution here is to replace the battery pack or have it rebuilt by a shop that specializes in LiIon battery pack rebuilding.

Hi u2canbe1
I guess your battery is dead.
I have an old Sony Vaio F-150 and I have the same problem as yours. I rarely use my laptop's battery but always leave it on with the battery inserted. Until one day, from the battery info it is either take long long time to e full or it takes 10 seconds to show from the very low battery level to fully charged. I have tried other known good battery from friends and its charging no problem, problem only exist on my original battery.
I guess you can either get a new battery or just get a new laptop instead, since the new battery priced rip off.
Hope this help
