15 Year Old Impact Driver Restoration

Bought this impact driver only 15$ cause it looks very old and the battery also dead. There is some water inside the box I think I couldn't get it back to work. Incidentally, I picked up another battery at good condition. The seller gave it to me for free. Finally, I can get this impact driver back to life. This tool is really powerful and greatly reduces striking noise. At the end of the video, you will see the drill testing and comparing.
