Tips on how to make the most of hearing aid batteries
Luckily there are a few ways to make hearing aid batteries work more efficiently. Our battery experts offer these tips for conversations about batteries:
1. Turn it off: Don’t keep your hearing aid running at night or when it isn’t in use. Open the battery drawer and remove the battery.
2. Use fresh produce: The fresher the batteries are the better, so pay attention to the expiry date. Do not keep large quantities of batteries in stock. And be advised that mercury free batteries have shorter lifespan than traditional batteries.
3. Keep it dry: Humidity can greatly decrease battery efficiency. Keep hearing aids away from water and as dry as possible when in humid environments.
4. Don’t keep it too dry: An environment that is too dry can also damage the batteries. The ideal relative air humidity is somewhere around 50 – 60 percent. This is why it is not a good idea to store batteries in the fridge, where the air humidity is generally low. Make sure the battery is removed when using a dry aid kit.
5. Keep it cool. Batteries like cool environments so keep them away from the heat – but do not store them in the refrigerator, where they may be damaged.
6. Keep them unopened: Don’t remove the batteries from the original packaging before you need to use them.
Battery life varies for each individual case
Customers asking for a precise answer to how long their batteries will be running are likely to be disappointed. While manufacturers give estimates on expected battery life, the real-life usage is dependent on each individual case.
“There is no easy way to tell how long hearing aid batteries will last in a given hearing aid, so providing your customers with a precise answer is not always possible,” says battery expert Ole Toft from Widex. “For professionals, it is therefore worthwhile to ask users to report back on their experiences with products from different manufacturers to obtain a general overview of real life current consumption.”
