Alienware m18x battery pack

HWmonitor shows that my battery wear has reached 96% and I want to replace the battery but there doesn't seem to be a place that sells this battery in Canada.

Also I've started to have overheating problems near the top left of the laptop that have caused fps to drop significantly to like 10 or 15. I've checked temperatures during these times and at most its only about 60 C so would it be the battery pack that is causing the problem? and where can I buy/order a new battery back?

edit tried playing with battery pack removed and only charger, fps still having problems
