I wouldn't suggest actually removing the battery, unless you absolutely have to. It's mounted by a double-sided adhesive tape, so taking it out is a bit tricky. My idea was just to disconnect it. You need to undo two screws that secure the power connector, right below the camera flash. The screws are under the plastic tape, just peel it off. When you remove those screws, carefully pull the connector up. That's it. Check the contacts for any signs of damage or corrosion, and clean up as needed. When reconnecting it, push firmly to make sure it sits properly.

To whom it may concern: STOP nagging about pressing the freakin' Thanks button!!! It is rude, stupid, and annoying as hell. I am not an idiot who needs a huge in-my-face reminder to press it, and I will press it when I feel thankful, not because you asked for it!
