Since it is your Mac, you will.

If you want to keep using it replace the battery.

Remove the battery from the MacBook immediately, as further expansion can cause harm to the computer.

New batteries for the MacBook are available here - http://www.amazon.com/A1185-MacBook-13-inch-Lithium-Polymer-Battery-White/dp/B00 UK7RTBG

Apple recommends disposing of your battery by taking it to them. Putting them in the trash is not good for the environment. See the last section of this article - http://www.apple.com/batteries/service-and-recycling/

Best of luck.
