According to VARTA Microbattery, it has developed the power one EVOLUTION in response to the needs of consumers who require reliable batteries with longer operating times. The power one EVOLUTION zinc-air battery is based on the Thin Foil Technology (TFT) and is said to be characterized by a “very high energy density.” Moreover, its capacity is said to be even higher than that of the tried-and-tested hearing aid batteries by VARTA Microbattery, resulting in a longer service life. The service life of the type 312 is reportedly up to 15% longer. The company says that field tests have shown that “nine out of ten customers would recommend the battery because of the significantly longer operating times.”

Q & As: This Week’s Top Selections
Q: How long should the battery last after a full charge? How much does Bluetooth activity affect this? —Brent Spehar
A: This is a great and very important question. Battery life is dependent on several factors including the amount of capacity of the battery, how fast the hearing aid drains the current, and the wear behaviors and habits of the user.
Much like how a car’s mileage range depends on its gas tank, the driving conditions, and the owner’s driving habits, a hearing aid’s battery life depends on the capacity of the battery, the wearer’s listening environments, and use of the various hearing aid functions, including audio streaming.
I like to use the example of an automobile. How many gallons of gas does the fuel tank hold or, for hearing aid batteries, how many mAh capacity is in the battery? How many miles per gallon does the car use or how many mA does the battery drain both when streaming and not streaming? And, finally, is the car driven on the highway or in the city and is the air conditioner on or off? Or, for hearing aids, how many hours per day does the hearing aid stream? Does the hearing aid use 2.4 GHz streaming or does it is use NFMI with an intermediate device that has its own battery? And, what features are turned on or off on the hearing aid?

Once you answer these questions, you can figure out “how long the battery will last after a full charge.” I gave some example calculations in the HRarticle: The Changing Landscape of Hearing Aid Batteries (Hearing Review, October 31, 2017).
Please note a factor we have learned in our electronics’ lab. Not all hearing aids are the same. Some 2.4 GHz products have current drains averaging 4.8-5.0 mA when streaming while other 2.4 GHz products using lower power Bluetooth will drain the battery at 3.0-3.4 mA while streaming. Some 2.4 GHz products when not streaming may have battery drains of 1.8-2.0 mA, while some of the newer products with bilateral beam-forming may drain the battery at 2.3-2.5 mA when not streaming.
The key is to know your products and know your patient’s listening habits. This is critical to good counseling.
Q: Is the life of the hearing aid circuit reduced as a result of using the rechargeable system? It did happen when [a previous model of hearing aid] were rechargeable. —Anjan Muhury
A: The ZPower Rechargeable System has been thoroughly evaluated by the hearing aid manufacturers and there is no indication that the system will have a negative effect on the life of the hearing aid circuit. The ZPower silver-zinc battery is designed to mimic the performance of traditional zinc-air batteries and is transparent to the DSP of the hearing aids. Extensive studies of hearing aids using the ZPower System also show the system including the ZPower silver-zinc batteries have no impact on the electrophysiologic performance of the hearing aids. Therefore, the ZPower System will not have a negative impact on the hearing aid circuitry or performance.
Previous Q & A’s
Q: What’s a realistic time frame for a rechargeable hearing aid battery to last?
A: Rechargeable silver-zinc batteries last about a year. They are removeable and therefore easily replaced. It is recommended that rechargeable silver-zinc batteries are replaced once a year by a hearing care professional.
Li-ion batteries are sealed within the hearing aid, and are usually removable only by the hearing aid manufacturer. They last approximately 4 to 5 years.
Q: What would happen if my patient accidentally places their hearing aids in the charger while they have zinc air batteries in them?
A: When the hearing aids are put on the charger, the charger will check to see what type of battery is in the hearing aid. If the charger detects a disposable zinc air battery, the lights on the charger will turn red. If the charger detects a silver-zinc battery, the lights on the charger will start blinking green; once the battery is fully charged, the lights will turn solid green.
Q: Can my patients overcharge a ZPower battery if they leave it in the charger for too long?
A: The batteries will not overcharge if left in the charger. It is a best practice to put the hearing aids back on the charger when the hearing aids are not being worn during the day. This will keep the hearing aids turned off and the batteries charged. For long-term storage, if batteries will not be used for over 2 weeks, the rechargeable batteries should be removed from the hearing aids and stored in a location where they will not touch each other or other metal objects.
Q: What happens when the silver-zinc rechargeable battery is getting low on power?
A: The hearing aid wearer will hear the low battery warning. Once the low-battery warning occurs or once a hearing aid shuts off due to a low battery condition, the battery door should not be opened and closed to reboot the hearing aid. Rebooting after the low battery warning can override the smart circuitry in the battery door into believing it has a traditional disposable battery installed and, although the hearing aid will continue to work for a short period, it may over-discharge the battery. If a low-battery warning from the hearing aids is received, the hearing aids should be placed in the charging base for charging or the batteries should be replaced with non-rechargeable batteries. The rechargeable batteries should not be stored with metal objects such as keys or coins.
Q: How often should the batteries be charged?
A: The batteries should be fully charged every night. Once the hearing aids are finished charging, the indicator lights turn from blinking green to solid green. A full charge may take up to 7 hours—the charge time varies based on how much the battery was depleted during the day. Do not try to extend battery life by charging every other day, as this increases the chances of depleting the battery. A fully depleted battery will take longer to charge and may not fully charge in time for next use.
Q: What happens if the hearing aid wearer forgets to charge the battery at night?
A: They can use a disposable zinc-air battery until it is convenient to re-charge the batteries—ideally the rechargeable batteries should be charged the next night. The rechargeable silver-zinc batteries are a gold color, so they will not be mixed up with zinc-air disposable batteries. The rechargeable batteries should be stored in a safe place and should not be stored with metal objects such as keys or coins.
Why do hearing aids sometimes use up batteries so quickly and how can they be more effIcient? It's a conversation I have often with my patients.
It’s no secret that battery life is a common complaint amongst hearing aid users. According to research from a 2010 MarkeTrak survey, battery lifetime is the challenge that receives the most negative ratings from users. Battery usage is a complicated factor and measuring it can be even more difficult. As hearing aid technology allows for stronger and more powerful devices, bigger and better batteries are required. This is difficult in a time when clients are demanding smaller and more discreet devices.
Environmental factors like temperature, humidity, air quality, and noise pollution can also have bad effects on batteries. Measuring battery life in hearing aids is a lot like measuring fuel efficiency in a car. But with a car, drivers can turn off certain features such as seat warmers, air condition, and radio sound to improve fuel efficiency. This isn’t possible with hearing aids, which are running and processing sound at all times using all their features. The only exception to this rule are functions that allow for streaming of sound from one device to another and can be turned off when not in use. Luckily there are a few ways to make hearing aid batteries work more efficiently.
So I suggest following these tips to get the most out of your batteries:
Turn it off: Don’t keep your hearing aid running at night or when it isn’t in use. Open the battery drawer and remove the battery.
Use fresh produce: The fresher the batteries are the better, so pay attention to the expiry date. Do not keep large quantities of batteries in stock. And be advised that mercury free batteries have shorter lifespan than traditional batteries.
Keep it dry: Humidity can greatly decrease battery efficiency. Keep hearing aids away from water and as dry as possible when in humid environments.
Don’t keep it too dry: An environment that is too dry can also damage the batteries. The ideal relative air humidity is somewhere around 50 – 60 percent. This is why it is not a good idea to store batteries in the fridge, where the air humidity is generally low. Make sure the battery is removed when using a dry aid kit.
Keep it cool: Batteries like cool environments so keep them away from the heat – but do not store them in the fridge, where they may be damaged.
Keep them unopened: Don’t remove the batteries from the original packaging before you need to use them.
Customers asking for a precise answer to how long their batteries will be running are likely to be disappointed. While manufacturers give estimates on expected battery life, the real-life usage is dependent on each individual case. “There is no easy way to tell how long hearing aid batteries will last in a given hearing aid, so providing your customers with a precise answer is not always possible,” says battery expert Ole Toft from Widex. “
I therefore think it is worthwhile to ask our users to report back on their experiences with products from different manufacturers to obtain a general overview of real life current consumption. If you have further questions about the battery life of your hearing aid or you need hearing aid batteries then please call us on 01494 765144.
