Lengthening the life of your hearing aid batteries could save you both time and money. If you can attain a few extra days out of each battery, that’s a good amount saved over the course of 12 months.
Luckily, there are actually a handful of things you can do to optimize your hearing aid battery life. If you can turn these eight guidelines into habits, you should notice a difference right away.
Here are eight ways to optimize the lifespan of your hearing aid batteries.
1. Purchase new hearing aid batteries
Hearing aid batteries unopened in the packaging can last for many 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 the batteries
Hearing aids take a unique kind 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.
Once this happens, the battery is live and the power will start depleting (reapplying the tab has no effect). That’s why you should remove the tab only if you plan on using the battery right away.
3. Employ the five-minute rule
Immediately after you remove the tab, don’t place the battery into the hearing aid right away. Instead, wait about 5-7 minutes. This will enable the air to fully activate the battery, increasing 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 keeping them in your refrigerator. The colder temperature decreases the release 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 develops from the refrigerator causes corrosion and a greater risk of early failure.
Simply store your batteries at room temperature for the greatest results.
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 inhibits drain and blocks 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
If you have a hearing aid dehumidifier, you won’t have to worry about where to store your hearing aids. At 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 some time, removing the batteries completely 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 bad for both the hearing aid batteries and the hearing aids themselves. That’s why it’s important to wash your hands before replacing the batteries.
