Like any electronic device, your hearing device requires a power supply. And that’s the hearing device battery. The latest technology in some devices can allow some devices to have both zinc air batteries and/or rechargeable solution. But batteries don’t last forever and need to be replaced. Is it a DIY project?
Yes, with steady hands and a few specialized tools, most users can swap out the batteries in their hearing device. Most hearing devices have a tone that you will hear that indicates the batteries need to be replaced. Having a battery tester will help address if the device is not working because of the battery. There are also now apps that will give you battery-level readouts if you’re hearing device is a “smart” model that connects to your smartphone.
Step one is to make sure you have the right batteries (no, one size does not fit all — if life were so simple). There are four color-coded sizes of hearing device batteries, from smallest to largest they are: size 10 (yellow), size 312 (brown), size 13 (orange), size 675 (blue). Yes, if life were simple that’d be 1, 2, 3, and 4.
Each hearing device is unique and you should always refer to the directions that came with it, but in general, there’s a door behind which the battery resides. That door needs to be gently pried open.
The next step is that the old battery must be taken out — there are magnetized tools that can make this much easier.
And the final step is — after removing the sticker/tape that is on new batteries and making sure the battery is facing the right direction — closing the door again. If this seems difficult to do then the battery is probably not inserted correctly, since most are designed to fit snugly and allow the door to be closed with a minimum of effort.
The webpage of your hearing device’s maker may have a video of the process you can watch. There are also how-to videos on YouTube.
