Expanding the life 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 good amount saved during the course of 12 months.

Fortunately, there are actually a number of things you can do to maximize the life of your hearing aid batteries. If you can convert these eight tips into habits, you should see a difference immediately.

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 several years. Unfortunately, like all batteries, power is diminished as each year passes, so it’s always more advantageous to buy the newer package.

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

Hearing aids use 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. Immediately after the tab is removed, air enters the holes and stimulates the zinc.

As soon as 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 anticipate using the battery immediately.

3. Utilize the five-minute rule

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

4. Store at room temperature

You may have heard that you can extend the life of your batteries by keeping them in your refrigerator. The frigid temperature slows the release of power, or so the thinking goes.

The issue is that the opposite occurs. Zinc-air batteries and moisture do not mix, and the condensation that occurs from the refrigerator causes corrosion and an increased 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 in use

When you’re not using your hearing aid, turn it off and open the battery door. This inhibits drain and prevents corrosion. But remember, 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. Purchase 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 extended periods

If you don’t plan 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 keep in mind that dirt, grime, and moisture are harmful for both the hearing aid batteries and the hearing aids themselves. That’s the reason it’s important to wash your hands before replacing the batteries.
