Sorry, there was a problem. Please try again later.It uses a flat round battery with the number 2016 on it. It is supposed to last a year. I think there is a picture of the battery in one of the photos from purchasers on the BB website. It is supposed to be readily available at "general merchandise stores"? Maybe they mean department stores or hardware stores? I did see some prices for them, one of them was a bulk purchase for about 32 cents each. Yes you have to unscrew the compartment to replace batteries.
