I'm using the stock 1300 battery and the battery door did "squeek" on the right side for me, which was rather annoying. I checked the forums about it and I saw this thread with the business card trick. I didn't have a business card around so I took a small piece of folded notebook paper and put it behind the battery door, but left a little out on the right side where the "squeeking" was, so you could see the paper. I clicked in the door wherever i could and then i pulled out the paper with the door still on...and waddya know? The "squeeking" stopped!
