Acer C720P Swollen Battery

As the title states, I have a C720P that I noticed has recently been having issues. The trackpad has been hard to press and the space around it was bulging. 

 

I opened it up and found the battery to have expanded to almost twice its size. To my knowledge this is not a standard occurrence. 

 

As some background info, the computer is never exposed to hot environments. It sits in my office and occasionally next to my bed. So I know it hasn't been exposed to anything it shouldn't. Additionally I have always used the Acer charger that it came with. 

 

Can anyone wiht Acer tell me why this is happenend? I understand that it's two years old but seriously, this shouldn't happen. My Surface Pro that I've had for three years is nothing like this.

this happens when an internal battery cell break, the only way to fix it is to replace it.

why it happened?

hard to say, they are battery and sometimes a little overheat or current drop or internal leak; it can happen on big production batch  (samsung note 7...)
