Stretching out the lifespan of your hearing aid batteries can save you both time and money. If you can attain a few extra days out of each battery, that’s a decent amount saved over the course of 12 months.

Fortunately, there are a number of things you can do to optimize your hearing aid battery life. If you can convert these eight tips into habits, you should see a difference right away.

Here are eight ways to maximize 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, 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 them

Hearing aids take a specialized kind of battery referred to as a zinc-air battery. Each one has a plastic tab covering small holes on the top of the battery. Right after the tab is removed, air enters the holes and stimulates the zinc.

As soon as this occurs, the battery is active and the power will begin draining (reapplying the tab has no effect). That’s why you should remove the tab only if you plan on using the battery immediately.

3. Use the five-minute rule

Once removing the tab, don’t insert the battery into the hearing aid immediately. Rather, wait approximately 5-7 minutes. This will permit the air to thoroughly activate the battery, increasing its life by as long as three days.

4. Store at room temperature

You may have heard that you can extend the life of your batteries by storing them in your refrigerator. The cold temperature decreases the discharge of power, or so the thinking goes.

The issue is that the exact opposite takes place. Zinc-air batteries and moisture do not mix, and the condensation that occurs from the refrigerator causes corrosion and an enhanced 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 minimizes drain and blocks corrosion. But remember, don’t store your hearing aids in the bathroom; temperature changes and dampness are hazardous to the batteries. Your bedroom side-table is probably the safest place.

6. Purchase 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, place your hearing aids in the dehumidifier to expel 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 plan on using your hearing aids for some time, removing the batteries completely will help prevent corrosion from collected moisture within the hearing aid.

8. Wash 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 the reason it’s important to wash your hands before changing the batteries.
