Option 1: Removing the battery

1. Carefully pull the black end of the sticker tight (see figure 1) and then use a pair of scissors to cut it through the middle (see figure 2).
2. Now you have to pull half of the adhesive strip off to the side very slowly to remove the adhesive strip (see figure 3). Repeat this process for the other half and then remove the battery. It’s a lot harder than it looks, and can take a while. If the strip tears, you have to switch to option 2.
3. Attach the new adhesive strips as shown in figures 4 and 5.
