Make sure to choose the correct file for your type of battery.
You need something to poke the pin out to remove the original pad and to reinstall it for the new one, I used the straight pick from a 2$ set from Harbor Freight. (Check the images.)
- Remove the pin holding the old pad in.
- Use an 1/8th inch drill bit to expand the hole after inserting the new pad so that it is lined up.
- Re-insert pin.
- Balance.
I printed without supports, as to keep the pin hole clear of any debris and make expanding it less of a hassle.
