One of the most commonly asked questions we get is, “How long should my batteries last?” On average, they should last about 4–7 days. Disposable batteries come in four different sizes: 10, 312, 13, and 675, depending on the style of hearing aid. These batteries are powered with zinc air, meaning that once you peel off the plastic sticker, the battery is activated. Keep in mind that the level of hearing loss has some correlation to how quick the battery will drain, as a higher degree of loss means that the battery will need to work harder to amplify more sound.
Here are a few tips to extend the life of your disposable battery:
- You should let the battery sit on the table for a full 5 minutes before you put it into your hearing aid.
- Whenever you are not wearing your hearing aids, you should open up the battery drawer and place the devices into a case. Once you open the battery drawer, you have turned off the aid and are now conserving some battery life.
- Keep your hearing aids clean! Excess earwax will drain the life of the battery faster.
The rechargeable battery was created as an advanced and environmentally-friendly option for users. A huge advantage to rechargeable batteries is that they only need to be replaced once per year. You won’t have to worry about running out of batteries or losing power during activities anymore. To charge them, you simply need to plug the hearing aid into the charging stand before bed and let them power up while you sleep. For those dealing with dexterity issues, the rechargeable batteries are particularly helpful — no more struggling to peel off the tiny plastic sticker or fumbling around to get the battery into the drawer.
Rechargeable batteries can operate a wireless streaming hearing for an entire day, recharge in a few of hours, last a full year before being replaced, and are fully recyclable at the end of its life. Are rechargeable batteries right for you and your lifestyle?
