Battery replacement starts with the size specified in the hearing-aid instructions. Similar packaging or a brand name is not enough to identify the right battery.
Identify the size
Check the hearing-aid instructions or the size on the existing battery packaging. Compare the size code and dimensions documented by the battery manufacturer.
Check the battery system
A hearing aid designed for disposable zinc-air batteries differs from a rechargeable system. Do not assume a rechargeable battery can replace a disposable one.
Check the retailer pack
Check quantity, size and expiry in the actual retailer listing. Store and handle batteries according to the manufacturer’s instructions and keep them away from children.
