Boosting the life of your hearing aid batteries can save you both time and money. If you can attain a couple of extra days out of each battery, that’s a decent amount saved during the course of 12 months.
Luckily, there are a handful of things you can do to maximize your hearing aid battery life. If you can turn these eight tips into habits, you should see a difference immediately.
Listed below are eight ways to maximize the lifespan of your hearing aid batteries.
1. Purchase new hearing aid batteries
Hearing aid batteries unopened in the packaging can last for years. Unfortunately, like all batteries, power is reduced 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 them
Hearing aids take a specialized type of battery called a zinc-air battery. Each one has a plastic tab covering tiny holes on the top of the battery. Immediately after the tab is removed, air enters the holes and stimulates the zinc.
After this occurs, the battery is live and the power starts draining (reapplying the tab has no effect). That’s why you should remove the tab only if you intend on using the battery immediately.
3. Employ the five-minute rule
After you remove the tab, don’t place the battery into the hearing aid immediately. Rather, wait approximately 5-7 minutes. This will allow the air to properly activate the battery, expanding its life by up to three days.
4. Store at room temperature
You may have read that you can prolong the life of your batteries by keeping them in your refrigerator. The cold temperature slows the release 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 causes corrosion and an enhanced risk of early failure.
Simply store your batteries at room temperature for the best results.
5. Leave the hearing aid battery door open when not being used
If you’re not using your hearing aid, turn it off and open the battery door. This decreases drain and prevents corrosion. But keep in mind, don’t store your hearing aids in the bathroom; temperature changes and moisture are hazardous 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. Every night, put your hearing aids in the dehumidifier to remove moisture and to provide a safe place for storage.
7. Take out 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 some time, 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 bad 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.
