Prolonging the life 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 a year.
Luckily, there are a number of things you can do to enhance your hearing aid battery life. If you can turn these eight tips into habits, you should observe a difference right away.
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 years. However, like all batteries, power is diminished as each year passes, 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 special kind of battery known as a zinc-air battery. Each one has a plastic tab covering small holes on the top of the battery. Once the tab is removed, air enters the holes and activates the zinc.
Right after this happens, the battery is active and the power will begin depleting (reapplying the tab has no effect). That’s why you should pull the tab only if you anticipate using the battery immediately.
3. Use the five-minute rule
Immediately after removing the tab, don’t place the battery into the hearing aid right away. Rather, wait around 5-7 minutes. This will permit the air to fully activate the battery, extending its life by up to three days.
4. Store at room temperature
You might have heard that you can prolong the life of your batteries by storing them in your refrigerator. The cooler temperature reduces the release of power, or so the reasoning goes.
The problem is that the opposite occurs. 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 best outcome.
5. Leave the hearing aid battery door open when not in use
When you’re not using your hearing aid, turn it off and open the battery door. This reduces drain and prevents corrosion. But remember, 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 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 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. Remove the batteries if you won’t be using your hearing aids for extended periods
If you don’t intend on using your hearing aids for some time, taking out the batteries completely will help protect against corrosion from collected moisture within the hearing aid.
8. Wash your hands before changing the batteries
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 crucial to wash your hands before replacing the batteries.
