Lengthening the lifespan of your hearing aid batteries can 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 a year.

Luckily, there are actually several things you can do to optimize your hearing aid battery life. If you can convert these eight tips into habits, you should notice a difference right away.

The following are eight ways to maximize the life of your hearing aid batteries.

1. Buy new hearing aid batteries

Hearing aid batteries unopened in the packaging can last for many years. Unfortunately, like all batteries, power is reduced as each year passes by, so it’s always better to purchase the newer package.

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

Hearing aids take a special type of battery called a zinc-air battery. Each one has a plastic tab covering tiny holes on the top of the battery. Once the tab is removed, air enters the holes and activates the zinc.

The moment 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 intend on using the battery immediately.

3. Use the five-minute rule

Just after you remove the tab, don’t place the battery into the hearing aid right away. Rather, wait around 5-7 minutes. This will permit the air to thoroughly activate the battery, extending its life by as long as three days.

4. Store at room temperature

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

The problem is that the exact opposite takes place. Zinc-air batteries and moisture do not mix, and the condensation that develops from the refrigerator causes corrosion and an increased risk of early failure.

Simply store your batteries at room temperature for the greatest outcome.

5. Leave the hearing aid battery door open when not in use

If you’re not using your hearing aid, turn it off and open the battery door. This reduces drain and prevents corrosion. But keep in mind, don’t store your hearing aids in the bathroom; moisture and temperature changes are hazardous to the batteries. Your bedroom side table is probably the safest 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. In the evenings, put your hearing aids in the dehumidifier to remove 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 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

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.
