We have a large selection of lithium and silver oxide button cell batteries (coin cell batteries). Due to their small size button cell batteries are used in small electrical devices such as watches, car keys, bank login keypads, remote controls, calculators and cameras. Whether you need a common CR2032 battery or a battery for your hearing-aid, you'll find it here. Different manufactures designate their batteries with different codes. If you are having difficulty finding a specific type of battery, our battery conversion table should help. It can be found under the documents tab on the product page of the battery in question.
