Wish my batteries didn't have logos on them
Very fine sandpaper will take them down to the metal, and they look like brushed aluminum. Then you can do whatever you want to them, if you don't like that look.
Are any of those stickers "non-slip" at all? Some butterfingers somewhere was asking about how to make the batteries less slippery, but not awful-looking (finally found something that Duct Tape wont fix). I told him to try shrink-tubing.
