Prolonging 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 good amount saved through the course of a year.

Luckily, there are several things you can do to enhance your hearing aid battery life. If you can turn these eight guidelines into habits, you should observe a difference right away.

Listed below are eight ways to optimize the lifespan of your hearing aid batteries.

1. Purchase new hearing aid batteries

Hearing aid batteries unopened in the package can last for years. However, just like all batteries, power is reduced as each year passes by, so it’s always more effective to purchase the newer package.

2. Don’t remove the tab until you’re ready to use them

Hearing aids take a specialized kind of battery called a zinc-air battery. Each one has a plastic tab covering tiny holes on the top of the battery. As soon as the tab is removed, air enters the holes and stimulates the zinc.

Once this occurs, the battery is active and the power will start depleting (reapplying the tab has no effect). That’s why you should remove the tab only if you anticipate using the battery immediately.

3. Employ the five-minute rule

Once removing the tab, don’t place the battery into the hearing aid immediately. Instead, wait around 5-7 minutes. This will allow the air to completely activate the battery, expanding its life by as much as three days.

4. Store at room temperature

You may have read that you can extend the life of your batteries by keeping them in your refrigerator. The colder temperature reduces the discharge of power, or so the reasoning goes.

The issue is that the opposite happens. Zinc-air batteries and moisture do not mix, and the condensation that occurs from the refrigerator causes corrosion and a heightened risk of premature failure.

Simply store your batteries at room temperature for the best 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 minimizes drain and blocks corrosion. But remember, don’t store your hearing aids in the bathroom; moisture and temperature changes are harmful 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. Every night, place your hearing aids in the dehumidifier to remove moisture and to provide a secure place for storage.

7. Take out the batteries if you won’t be using your hearing aids for prolonged periods

If you don’t anticipate using your hearing aids for some time, taking out the batteries completely will help prevent corrosion from collected moisture within the hearing aid.

8. Clean your hands before changing the batteries

You should always keep in mind that dirt, grime, and moisture are bad for both the hearing aid batteries and the hearing aids themselves. That’s why it’s crucial to wash your hands before changing the batteries.
