Hearing aid batteries
There are four standard sizes of batteries used in hearing aids, and each has its own color code on the battery package. The battery size you should use is given in the hearing aid’s instructions for use.
Contact a hearing care professional to find out how to get the right batteries for your hearing aids. Your hearing care professional can provide you with the MultiTool, which makes it easy to handle the batteries as well as clean the hearing aids.
