Boosting the lifespan of your hearing aid batteries can save you both time and money. If you can attain a couple of extra days out of each battery, that’s a decent amount saved over the course of 12 months.
Luckily, there are actually several things you can do to maximize your hearing aid battery life. If you can convert these eight tips into habits, you should observe a difference immediately.
Here are eight ways to maximize the life of your hearing aid batteries.
1. Buy new hearing aid batteries
Hearing aid batteries unopened in the package can last for years. Unfortunately, just like all batteries, power is diminished 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 use a specialized type of battery known as 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 stimulates the zinc.
The moment this happens, 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 intend on using the battery right away.
3. Utilize the five-minute rule
Immediately after removing the tab, don’t place the battery into the hearing aid right away. Rather, wait approximately 5-7 minutes. This will permit the air to thoroughly activate the battery, enhancing its life by up to three days.
4. Store at room temperature
You may have heard that you can prolong the life of your batteries by storing them in your refrigerator. The colder temperature slows the discharge of power, or so the thinking goes.
The problem is that the opposite takes place. 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 being used
If you’re not using your hearing aid, turn it off and open the battery door. This reduces drain and blocks 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 best place.
6. Invest in 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 eliminate 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 entirely will help protect against corrosion from trapped moisture within the hearing aid.
8. Wash 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 why it’s crucial to wash your hands before changing the batteries.
