Prolonging the lifespan of your hearing aid batteries could save you both time and money. If you can get a couple of extra days out of each battery, that’s a good amount saved over the course of 12 months.
Luckily, there are actually a number of things you can do to maximize your hearing aid battery life. If you can turn these eight recommendations into habits, you should notice a difference immediately.
Listed below 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 several years. However, like all batteries, power is reduced 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 the batteries
Hearing aids use a specialized type of battery referred to as a zinc-air battery. Each one has a plastic tab covering tiny holes on the top of the battery. As soon as the tab is removed, air enters the holes and stimulates the zinc.
Right after 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. Use the five-minute rule
After removing the tab, don’t insert the battery into the hearing aid immediately. Rather, wait approximately 5-7 minutes. This will permit the air to properly activate the battery, enhancing its life by as much as three days.
4. Store at room temperature
You might have heard that you can extend the life of your batteries by storing them in your refrigerator. The colder temperature decreases the discharge of power, or so the thinking goes.
The issue is that the exact opposite takes place. Zinc-air batteries and moisture do not mix, and the condensation that occurs from the refrigerator leads to corrosion and an elevated 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
If you’re not using your hearing aid, turn it off and open the battery door. This minimizes drain and blocks corrosion. But keep in mind, 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. Invest in a hearing aid dehumidifier
With a hearing aid dehumidifier, you won’t have to worry about where to store your hearing aids. At night, place your hearing aids in the dehumidifier to remove moisture and to provide a safe place for storage.
7. Remove 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 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 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.
