Battery Blocker
The Battery Blocker is the simplest way to disconnect an iPad battery. Completely non-conductive, this little wedge separates the battery contacts from the logic board on certain devices. Simply remove the retaining screw above the battery contact and slide the pick underneath the logic board.
The Battery Blocker works with iPad Air, iPad 2, iPad 3, iPad 4, iPad 5, iPad 6, and some MacBook models.
