Well, I just got a replacement door because the door wasn't sealed properly after use. The hooks are more curved and the front of the device looks proper. However, there is still one corner sticking up which also makes a metallic noise when I set it down. So I tried putting some wall stickers on there, but they were too think so I found some double stick tape and stuck it on the rim surrounding the battery and then the battery itself. I might request another door from Apple, but for the moment is this a OK thing to do? I had thought about the detrimental effects of this thin plastic on the battery, but the tongue (to take out the battery) looks as if it's plastic as well. tl;dr: Is putting tape on my battery to fix the door issues a bad idea?
