Hearing Aid Battery Sizes

A page for every hearing aid battery size, for every combination of size and use pattern, and for every device style: the tab colour, the IEC designation, the dimensions, which devices take it, and how long it lasts.

24 pages in this section. Published figures from named standards bodies and regulators.

• What Battery Does a Completely in canal Hearing Aid Take A completely in canal hearing aid most commonly takes a size 10 battery, the yellow one, IEC PR70. Makers differ, so the tab colour on the packet you use now is the reliable identifier.
• What Battery Does a In the ear Hearing Aid Take A in the ear hearing aid most commonly takes a size 312 battery, the brown one, IEC PR41. Makers differ, so the tab colour on the packet you use now is the reliable identifier.
• What Battery Does a Receiver in canal Hearing Aid Take A receiver in canal hearing aid most commonly takes a size 312 battery, the brown one, IEC PR41. Makers differ, so the tab colour on the packet you use now is the reliable identifier.
• What Battery Does a Behind the ear Hearing Aid Take A behind the ear hearing aid most commonly takes a size 13 battery, the orange one, IEC PR48. Makers differ, so the tab colour on the packet you use now is the reliable identifier.

Not medical advice, not a hearing test, not a diagnosis. Everything in this section is general information compiled from published standards, regulatory classifications, manufacturer specifications and the consensus of verified owner reviews. The charts explain what a measurement shows. They cannot tell you what your hearing is, and nothing on this site can measure it. Only a licensed audiologist or physician can evaluate hearing. If hearing changed suddenly, affects one ear only, or comes with pain, drainage, dizziness or ringing alongside weakness or numbness, contact a doctor promptly rather than reading a chart.
