Increasing the lifespan of your hearing aid batteries can 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 during the course of a year.
Fortunately, there are a handful of things you can do to enhance the life of your hearing aid batteries. If you can convert these eight guidelines into habits, you should observe a difference immediately.
Here 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. However, just like all batteries, power is reduced as each year passes by, so it’s always more effective to buy the newer package.
2. Don’t remove the tab until you’re ready to use them
Hearing aids use a special type of battery called 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.
As soon as this happens, the battery is live and the power will start depleting (reapplying the tab has no effect). That’s why you should pull the tab only if you plan on using the battery right away.
3. Apply the five-minute rule
Once removing the tab, don’t insert the battery into the hearing aid immediately. Instead, wait about 5-7 minutes. This will enable the air to fully activate the battery, enhancing 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 keeping them in your refrigerator. The cold temperature decreases the discharge of power, or so the thinking goes.
The problem is that the exact opposite takes place. Zinc-air batteries and moisture do not mix, and the condensation that develops from the refrigerator leads to corrosion and an increased 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 being used
When you’re not using your hearing aid, turn it off and open the battery door. This minimizes drain and prevents corrosion. But keep in mind, don’t store your hearing aids in the bathroom; temperature changes and dampness are hazardous 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 keep your hearing aids. Each night, put your hearing aids in the dehumidifier to expel moisture and to provide a secure place for storage.
7. Remove 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, taking out the batteries completely will help protect against corrosion from trapped moisture within the hearing aid.
8. Wash your hands before changing the batteries
You should always keep in mind that dirt, grime, and moisture are bad for both the hearing aid batteries and the hearing aids themselves. That’s the reason it’s important to wash your hands before changing the batteries.
