I found my thermometer's battery was dead and (of all things) not working, so instead of buying an overpriced new one I did a little research to find it out which ones I need. Instead of buying 20 of these as I have other things with buttons I wanted to buy a multi pack and this seemed to be the best. The package is bigger than I thought, about the size of a piece of computer paper, but still thin and doesn't take up too much space. I wish each cell had a perforated back so I could slide one out and keep it in order, but I had to cut the plastic in front to get just one. Fits my thermometer! No fever! They come in handy when my jewelry or laser pointers (for pets) run out of battery.
