Dell 9200 battery stops charging?

[JMP300z]

I have pretty much never used my dell inspiron 9200 not plugged in. All of a sudden the battery just decided to stop working and im getting the blinking orange light and its not charging. Its about 2 yrs old. I was playing a pc game and the laptop suddenly overheated (never happened b4) and the battery fried. I checked and the battery was not the source of heat nor is it one recalled.

Short of buying a new battery is there anything I can do?
