6 tips for getting the most out of your hearing aid batteries
- Hearing aid battery life expectancy
Batteries can last between three and ten days, depending on your hearing loss, how long you wear your hearing aid for, and the age of the batteries. - The 5-minute rule for hearing aid batteries
Let the battery rest for five minutes after removing the sticker. This will allow the air to activate the battery, which can expand its life by days. - Hearing aid battery bounce test
Drop the battery on a table from a height of around 10–15 cm. If the battery bounces several times, you should replace it. - Conserve your hearing aid battery life
Leave the battery door open when you remove your hearing aids at night. - What should you do with old hearing aid batteries?
Find your closest battery recycling point. - Storing hearing aid batteries
Keep your batteries in a dry place at room temperature.
Hearing aids with rechargeable batteries
Using rechargeable batteries means you don’t have to buy new batteries or throw away used ones. Your wallet and the environment will both benefit.
- No need to replace batteries weekly (they last 4–5 years)
- Recharge your hearing aids at night
- Get a full charge from just 3–4 hours of charging time
- Save money over time
