Whats wrong with the words on the image? They look clear on my screen.
Berryaddictnoza, no. As in the image, the small strip of tape is placed in the compartment where the arrow points. It simply removes a tiny amount of space in the compartment so the battery fits tighter. It works simply as a wedge. You put it in and forget about it. If you never swap your battery out you could simply cut a 1/16th inch of business card and put it in that wedge too.
Simply a very narrow strip of tape is placed in the compartment where the arrow is. The white-out part in the center of the image is simply to remove my PIN/Serial Numbers. No adhesive is in contact with the battery. It just serves to take up that ~.1mm of space that is the problem. This solution works.
Here is an image explanation.
