Expanding the lifespan of your hearing aid batteries can save you both time and money. If you can get a few additional days out of each battery, that’s a decent amount saved over the course of a year.
Luckily, there are a handful of things you can do to optimize the life of your hearing aid batteries. If you can turn these eight tips into habits, you should notice a difference right away.
Here are eight ways to maximize the life of your hearing aid batteries.
1. Buy new hearing aid batteries
Hearing aid batteries unopened in the package can last for years. Unfortunately, just like all batteries, power is reduced as each year passes by, so it’s always more advantageous to purchase the newer package.
2. Don’t remove the tab until you’re ready to use the batteries
Hearing aids use a specialized type of battery known as a zinc-air battery. Each one has a plastic tab covering tiny holes on the top of the battery. After the tab is removed, air enters the holes and stimulates the zinc.
Once this occurs, the battery is active and the power will begin depleting (reapplying the tab has no effect). That’s why you should pull the tab only if you plan on using the battery immediately.
3. Implement the five-minute rule
After you remove the tab, don’t place the battery into the hearing aid immediately. Rather, wait about 5-7 minutes. This will permit the air to completely activate the battery, extending its life by up to three days.
4. Store at room temperature
You may have heard that you can prolong the life of your batteries by keeping them in your refrigerator. The frigid temperature decreases 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 occurs from the refrigerator causes corrosion and a greater risk of early failure.
Simply store your batteries at room temperature for the best results.
5. Leave the hearing aid battery door open when not being used
When you’re not using your hearing aid, turn it off and open the battery door. This decreases drain and prevents corrosion. But keep in mind, don’t store your hearing aids in the bathroom; moisture and temperature changes are detrimental to the batteries. Your bedroom side table is probably the best place.
6. Invest in a hearing aid dehumidifier
With a hearing aid dehumidifier, you won’t have to worry about where to keep your hearing aids. At night, place your hearing aids in the dehumidifier to remove moisture and to provide a safe place for storage.
7. Remove the batteries if you won’t be using your hearing aids for extended periods
If you don’t anticipate using your hearing aids for a while, removing the batteries completely will help prevent corrosion from trapped moisture within the hearing aid.
8. Wash your hands before changing the batteries
You should 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 crucial to wash your hands before replacing the batteries.
