Stretching the lifespan 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 through the course of 12 months.
Luckily, there are actually a number of things you can do to enhance 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. Buy new hearing aid batteries
Hearing aid batteries unopened in the packaging can last for years. Unfortunately, just like all batteries, power is diminished as each year passes by, 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 take a special 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. The moment the tab is removed, air enters the holes and activates the zinc.
The moment this occurs, the battery is active and the power starts draining (reapplying the tab has no effect). That’s why you should remove the tab only if you plan on using the battery immediately.
3. Employ the five-minute rule
Immediately after removing the tab, don’t insert the battery into the hearing aid right away. Instead, wait around 5-7 minutes. This will enable the air to fully activate the battery, increasing its life by as much as three days.
4. Store at room temperature
You may have heard that you can extend the life of your batteries by storing them in your refrigerator. The colder temperature reduces 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 causes corrosion and a heightened risk of premature failure.
Simply store your batteries at room temperature for the best outcome.
5. Leave the hearing aid battery door open when not being used
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 best place.
6. Invest in a hearing aid dehumidifier
If you have a hearing aid dehumidifier, you won’t have to worry about where to keep your hearing aids. Each night, put your hearing aids in the dehumidifier to expel 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 some time, removing the batteries entirely will help protect against 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.
