Lengthening the life of your hearing aid batteries can save you both time and money. If you can get a couple of extra days out of each battery, that’s a decent amount saved over the course of a year.

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

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

1. Purchase new hearing aid batteries

Hearing aid batteries unopened in the packaging can last for years. Unfortunately, like all batteries, power is reduced as each year passes, 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 unique 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. As soon as the tab is removed, air enters the holes and activates the zinc.

After this happens, the battery is active and the power starts depleting (reapplying the tab has no effect). That’s why you should pull the tab only if you plan on using the battery right away.

3. Employ the five-minute rule

Immediately after you remove the tab, don’t insert the battery into the hearing aid right away. Instead, wait approximately 5-7 minutes. This will permit the air to properly activate the battery, extending its life by as much as three days.

4. Store at room temperature

You may have read that you can prolong the life of your batteries by keeping them in your refrigerator. The colder temperature decreases the release of power, or so the thinking goes.

The issue is that the exact opposite occurs. Zinc-air batteries and moisture do not mix, and the condensation that occurs from the refrigerator leads to corrosion and an enhanced risk of premature 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 prevents corrosion. But remember, don’t store your hearing aids in the bathroom; temperature changes and moisture are harmful to the batteries. Your bedroom side table is probably the best place.

6. Purchase a hearing aid dehumidifier

With a hearing aid dehumidifier, you won’t have to worry about where to keep your hearing aids. Each night, put your hearing aids in the dehumidifier to eliminate 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, taking out the batteries completely will help prevent corrosion from trapped moisture within the hearing aid.

8. Clean your hands before changing the batteries

Always remember that dirt, grime, and moisture are bad 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.
