Getting the most from Hearing Aid Batteries
Technology is advancing faster than ever, including something as simple as a hearing aid battery. Thankfully, these changes have been monitored and regulated closely, reducing the level of technical expertise and variables that could prevent those who are not technically savvy from accessing better care. The hearing aid industry has even introduced a system that allows users to easily find the correct battery for their hearing aids in the form of color-coded tabs.
These quality of life improvements make owning a hearing aid more convenient than it was decades ago. It is important to review all pertinent information on owning a hearing aid if you are someone who has just starting wearing one or if you feel as though you might be requiring a new one in the future.
Here are some more tips you should know about hearing aid batteries:
How long will a battery last?
The old train of thought was that you should replace your hearing aid battery about once per week. This would be highly inaccurate today, as hearing aids can vary widely on their power draw and longevity of the battery. Environmental factors, such as humidity and temperature can also play a role in how long your battery will last. Even altitude has been measured to have an impact on battery life.
Newer hearing aids are more precise and therefor need more power than older analog devices. When you buy a new hearing aid, you are given a more precise measure of how much you should expect to get out of a battery, typically between 5-8 days. If your battery dies well short of that estimate, you might need to get your hearing air repaired or replaced.
If you notice that your hearing aids start to dip in volume or take on a noisy or distorted background, then this means your batteries are starting to fail. Modern hearing aids will actually give you a warning beep before your hearing starts to be affected, which is very critical for those who rely on their hearing for work, operating machinery, and driving, for example.
It’s a good idea to carry a back-up pair of batteries wherever you go, but be sure not to store them near any metal objects or any place (like the glovebox) if has the potential to get extremely hot.
What are “Zinc Air” batteries?
These are the standard for most hearing aids—Zinc Air batteries are activated by the air, a chemical reaction starts when the tab is pulled to expose the zinc to the oxygen in the air and continues until the battery is depleted. These batteries last for up to three years as long as the tabs remain on. They are more environmentally friendly and they are cheaper than traditional batteries. This is mostly due to the fact that they have much larger capacity than standard batteries.
If you’re going to use a Zinc Air battery, remember to let the battery “breathe” for five minutes after removing its tab. This is necessary to allow the chemical process to initiate and fully power up the battery. It has to be at least five minutes, too little and you won’t have enough surface area of the battery activated, which can decrease the life of your battery by as much as half of its overall lifespan.
Good Battery Care Tips
- Every time you take out your hearing aids, remember to turn it off or remove the battery.
- Never store your battery in a hot, humid, or extremely cold place.
- Dispose of batteries immediately to avoid mixing new and old ones together.
- Make sure your hands are clean before changing batteries. Any dirt or oils from your hands can cause poor contact points and/or corrode them over time.
- Before going to sleep, remove the battery from your hearing aid and leave the compartment open to avoid moisture build-up.
- You can buy your batteries online in bulk to save money, but be careful not to accidently buy cheap knock-offs. These could damage your hearing aid device.
- Dry storage boxes and hearing aid dehumidifiers can protect both your hearing aid and its batteries. They also provide a safe place to store them when you remove them.
