Lengthening 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 decent amount saved over the course of a year.
Fortunately, there are several 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 immediately.
Listed below 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 effective to buy the newer package.
2. Don’t remove the tab until you’re ready to use the batteries
Hearing aids use a specialized kind of battery referred to as a zinc-air battery. Each one has a plastic tab covering tiny holes on the top of the battery. Right after the tab is removed, air enters the holes and activates the zinc.
Once this occurs, 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 intend on using the battery right away.
3. Implement the five-minute rule
Once you remove the tab, don’t place the battery into the hearing aid right away. Rather, wait approximately 5-7 minutes. This will allow the air to completely activate the battery, increasing its life by as much as three days.
4. Store at room temperature
You may have read that you can prolong the life of your batteries by storing them in your refrigerator. The cold temperature reduces the discharge of power, or so the reasoning 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 an elevated risk of premature 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 decreases drain and prevents corrosion. But remember, don’t store your hearing aids in the bathroom; temperature changes and dampness are detrimental to the batteries. Your bedroom side-table is probably the safest place.
6. Purchase a hearing aid dehumidifier
With a hearing aid dehumidifier, you won’t have to worry about where to store your hearing aids. Each night, place 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 extended periods
If you don’t anticipate using your hearing aids for a while, taking out the batteries entirely will help protect against corrosion from collected 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 the reason it’s important to wash your hands before replacing the batteries.
