8 Ways to Make Your Hearing Aid Batteries Last Longer
Prolonging the lifespan of your hearing aid batteries could save you both time and money. If you can attain a couple of additional days out of each battery, that’s a decent amount saved over the course of 12 months.
Fortunately, there are actually a number of things you can do to optimize the life of your hearing aid batteries. If you can turn these eight recommendations into habits, you should see a difference right away.
The following are eight ways to maximize the life of your hearing aid batteries.
1. Purchase new hearing aid batteries
Hearing aid batteries unopened in the packaging can last for many years. Unfortunately, like all batteries, power is reduced as each year passes, so it’s always better to purchase the newer package.
2. Don’t remove the tab until you’re ready to use the batteries
Hearing aids take a special type of battery referred to as a zinc-air battery. Each one has a plastic tab covering small holes on the top of the battery. The moment the tab is removed, air enters the holes and stimulates the zinc.
After this occurs, the battery is live and the power starts draining (reapplying the tab has no effect). That’s why you should pull the tab only if you anticipate using the battery immediately.
3. Employ the five-minute rule
Immediately after you remove the tab, don’t place the battery into the hearing aid immediately. Rather, wait around 5-7 minutes. This will enable the air to fully activate the battery, increasing its life by as much as three days.
4. Store at room temperature
You may have heard that you can prolong the life of your batteries by storing them in your refrigerator. The colder temperature slows the release of power, or so the thinking goes.
The issue is that the opposite occurs. Zinc-air batteries and moisture do not mix, and the condensation that develops from the refrigerator causes corrosion and an enhanced risk of early failure.
Simply store your batteries at room temperature for the greatest outcome.
5. Leave the hearing aid battery door open when not in use
When you’re not using your hearing aid, turn it off and open the battery door. This minimizes drain and blocks corrosion. But keep in mind, don’t store your hearing aids in the bathroom; temperature changes and dampness are harmful to the batteries. Your bedroom side table is probably the safest place.
6. Invest in a hearing aid dehumidifier
If you have a hearing aid dehumidifier, you won’t have to worry about where to keep your hearing aids. Every night, put your hearing aids in the dehumidifier to expel moisture and to provide a secure place for storage.
7. Remove the batteries if you won’t be using your hearing aids for prolonged periods
If you don’t plan on using your hearing aids for some time, removing the batteries entirely will help protect against corrosion from trapped moisture within the hearing aid.
8. Wash your hands before changing the batteries
Always keep in mind that dirt, grime, and moisture are harmful for both the hearing aid batteries and the hearing aids themselves. That’s the reason it’s crucial to wash your hands before changing the batteries.
