Hearing Aid Batteries Guide
For those who are hard of hearing, a hearing aid is an invaluable device and something that you might even rely on day to day. Improving your hearing and helping it to become easier to hear those around you are vital benefits of wearing a hearing aid; it may even restore some self-confidence too. With that in mind, it’s important that you buy the right hearing aid batteries to ensure they are long-lasting and consistent.
Hearing aid battery sizes
There are 4 common sizes of hearing aid batteries, known as 10, 13, 312 and 675. Battery manufacturers use an industry colour code on the packaging to help you identify the size; 10 is yellow, orange is 13, brown is 312 and blue is 675.- Size 10 batteries can be used in ITC (in the canal) and CIC (completely in canal) hearing aids
- Size 13 batteries are great for BTE (behind the ear) and ITE (in the ear) hearing aids
- Size 312 batteries can be used in ITC and ITE hearing aids
- Size 675 batteries can be used in BTE hearing aids
Type of hearing aid batteries
Hearing aid batteries use to be produced using tiny amounts of mercury; this helped conductivity and stabilisation of the internal components. This is no longer the case. The most popular type of hearing aid battery on the market remains the zinc air button battery, despite rechargeable batteries now becoming available. The zinc button batteries have been designed to allow maintained performance and maximum power. Zinc air batteries are air-activated, so your new hearing aid batteries will come covered with a sticker or tab. This makes sure the batteries are as fresh as can be. Make sure you only remove this tab when you’re ready to install the batteries into your hearing aid; this activates the battery. Our range of Rayovac hearing aid batteries will fit in most industry standard hearing aids. They come in packs of 6, so you’ll always have a spare battery when you need it!
Looking after your hearing aid batteries
Please bear in mind, the amount of time your hearing aid batteries will last depends largely on how often you use them, as well as the amplification of your hearing aid. You should store your spare hearing aid batteries at room temperature; anywhere too hot or too cold can affect the battery life. Avoid carrying loose hearing aid batteries in your pocket or purse; if they come into contact with a metal object, they can discharge or even leak.
