I do not see any battery on your picture! There is the pcb with a hole in the middle and a potted piece which holds just your game rom inside it.

You should try to reload the raspberry image.
Or: use another SD card
Or: did you changed any overclocking settings inside of config.txt?

-measure on which inductor you get 5V to ground.
-one this point you inject your 5V finally.
