Battery ends in minutes

[RogellParadox]

Hi, guys. I've experiencing it for weeks.
It started more or less a month ago.
Well, the problem is: when I put my tablet to charge, even if it's in 2%, it goes quickly to 90% ,99% or 100%
I charge it 4 hours and, when it's supposed to be done and I turn on, its level is 87%, 52%, again, depending on the turn.
Last time I charged for 3 hours and it showed up 86%. In one minute, went to 52%, then 24% and finally 2%.
It all in more or less three minutes.
I also could percept that some time, it was showing 14% left. I turned it off and turned it on and then it showed 76%.
I deleted that file from battery status and even reset the tablet, but nothing worked.
I also tried to open the tablet, but it's hard, if I force it, I'll screw it up
What you think? Is it battery or software problem? What could I do?
Sorry for my bad english...

I think its your battery, remove it and check whether its swollen. It could also be your charger, if its not the right charger, then it will mess your battery.
