The device requires 2xAG12 batteries. Each battery manufacturer uses a different numbering system for coin cell batteries. AG12 corresponds to these numbers: 301, 386, L1142, LR1142, LR43. A well-stocked hardware store or electronics store has them in stock. The instructions also state that AG12 is a lithium cell. No, that is not so. AG12 and all of its equivalents listed above are alkaline elements. Apart from the missing batteries I am satisfied with the product.
