Increasing 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 good amount saved over the course of a year.

Fortunately, there are actually several things you can do to maximize your hearing aid battery life. If you can turn these eight tips into habits, you should observe a difference right away.

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

1. Buy new hearing aid batteries

Hearing aid batteries unopened in the package can last for many years. However, just like all batteries, power is diminished as each year passes by, so it’s always better to buy the newer package.

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

Hearing aids use a special type of battery known as a zinc-air battery. Each one has a plastic tab covering tiny 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 live 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. Employ the five-minute rule

Once you remove the tab, don’t insert the battery into the hearing aid immediately. Rather, wait around 5-7 minutes. This will enable the air to completely activate the battery, enhancing its life by up to three days.

4. Store at room temperature

You might have heard that you can prolong the life of your batteries by storing them in your refrigerator. The colder 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 leads to corrosion and an enhanced risk of premature failure.

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

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 decreases drain and prevents corrosion. But remember, 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 safest place.

6. Purchase a hearing aid dehumidifier

With a hearing aid dehumidifier, you won’t have to worry about where to store your hearing aids. Each night, put 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 intend on using your hearing aids for a while, removing the batteries entirely will help prevent corrosion from collected moisture within the hearing aid.

8. Clean 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 changing the batteries.
