Good instructions! A trick I have learned is to use a small set of straight surgical clamps to remove battery adhesive. Use you tweezers or finger to pull the adhesive out a bit and clamp the adhesive at a 90 angle so that the clamp is across the whole strip.. Then pull the adhesive with the clamp still at a right angle and roll the adhesive up on the clamp . Just like opening a tin of Kipper Snacks while pulling gently.
