Varta to Unveil Power One Evolution at 2019 AAA Show
The significance of the quality of a tailor-made power supply is emphasized by Stiftung Warentest, a German consumer test organization. In the current test, VARTA Microbattery GmbH—a company supplying retail and OEM batteries for electronics companies—announced that it came out on top among the 14 hearing aid batteries tested in the “most important types,” 312 and 10.
“The test winner rating has motivated us to intensify our research efforts to develop an even better product,” said Torsten Schmerer, general manager, healthcare, at VARTA Microbattery GmbH.
The result of these efforts is the power one EVOLUTION. The newly developed product as well as the test-winning batteries and the full range of batteries and rechargeable batteries were showcased on March 22-23, 2019 at the 41st Congrès des Audioprothésistes in the Palais des Congrès de Paris (UNSAF). They will also be showcased on March 27-29, 2019 at the Congress of the American Academy of Audiology (AAA) in Columbus, USA, Stand 630.

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.”

“The limited space in hearing aids is the reason why the power supply can only be increased by improving the technology of the hearing aid. Our expertise is based on the synergy of extensive material research, many years of experience in cell development, and our own production equipment technology,” said Schmerer.

Hearing aid batteries last how long?
How long will a fully charged hearing aid last
How long should the hearing aid battery last after a full charge, and how does Bluetooth affect this?
The Chalfont hearing centre is a premier independent hearing company based in Chalfont Buckinghamshire. We supply all manufacturers hearing aid batteries and conduct hearing tests. Microsuction ear wax removal is our speciality here and we also still use the traditional technique of water ear irrigation if you prefer. Hearing aid batteries can be bought over the counter or we can post them to you if this is easier.
This Weeks blog is about the hearing aid battery and how long these should last from a full charge.

How long should the hearing aid battery last after a full charge, and how does Bluetooth affect this
Q: How long should the battery last after a full charge? How much does Bluetooth activity affect this?
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.
Hearing aid batteries last how long?
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?

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.
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.
