What Size Battery Do You Need?

Refer to the documentation that came with your hearing aid to determine which battery size is right for your aid, or consult your hearing care professional. Battery sizes are standardised across the industry, although manufacturers may name their products differently. Most manufacturers use the industry-standard colour code which can usually be found on battery tabs and packaging.
