Lengthening the life of your hearing aid batteries could save you both time and money. If you can get a few extra days out of each battery, that’s a decent amount saved during the course of 12 months.
Fortunately, there are actually several things you can do to maximize your hearing aid battery life. If you can convert these eight tips into habits, you should observe a difference right away.
Here are eight ways to optimize the lifespan of your hearing aid batteries.
1. Buy new hearing aid batteries
Hearing aid batteries unopened in the packaging can last for several years. However, just like all batteries, power is diminished as each year passes, so it’s always more effective to purchase the newer package.
2. Don’t remove the tab until you’re ready to use the batteries
Hearing aids use a special type of battery known as a zinc-air battery. Each one has a plastic tab covering small holes on the top of the battery. Once the tab is removed, air enters the holes and stimulates the zinc.
The moment this occurs, the battery is active and the power starts depleting (reapplying the tab has no effect). That’s why you should remove the tab only if you plan on using the battery right away.
3. Apply the five-minute rule
After you remove the tab, don’t insert the battery into the hearing aid right away. Instead, wait approximately 5-7 minutes. This will enable the air to thoroughly activate the battery, enhancing its life by as much as three days.
4. Store at room temperature
You might have heard that you can extend the life of your batteries by keeping them in your refrigerator. The cooler temperature slows the discharge of power, or so the reasoning goes.
The problem is that the exact opposite happens. Zinc-air batteries and moisture do not mix, and the condensation that develops from the refrigerator causes corrosion and a higher risk of early failure.
Simply store your batteries at room temperature for the greatest results.
5. Leave the hearing aid battery door open when not being used
If you’re not using your hearing aid, turn it off and open the battery door. This inhibits drain and prevents 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. In the evenings, place your hearing aids in the dehumidifier to eliminate moisture and to provide a safe place for storage.
7. Remove the batteries if you won’t be using your hearing aids for prolonged periods
If you don’t intend on using your hearing aids for a while, removing the batteries completely will help prevent corrosion from collected moisture within the hearing aid.
8. Clean your hands before changing the batteries
Always remember that dirt, grime, and moisture are harmful for both the hearing aid batteries and the hearing aids themselves. That’s the reason it’s important to wash your hands before replacing the batteries.
