The Benefits of Rechargeable Hearing Aids

Rechargeable Hearing Aids

Contained within a tiny hearing aid is an impressive feat of technology, research and design, which has taken years of development, funding and progress. The advancement of hearing devices has largely benefitted users, with features ranging from direct streaming of music and phone conversations to automatic pre-set preferences through the use of GPS systems.

One element of hearing instruments that is still taking time to catch up, however, is the batteries upon which those hearing devices rely.

Traditional hearing aid batteries

Although new technology that has been built into hearing instruments can be hugely beneficial for people who experience hearing loss, the cost of these batteries can really add up – both in terms of your wallet and the environment at large.

The huge majority of hearing instruments on the market rely on traditional hearing aid batteries. Hearing devices without the bells and whistles (in other words, without the advances in wireless and digital technology such as GPS and Bluetooth) can function on zinc air hearing aid batteries for up to one to two weeks. Considering you may use your hearing devices for 12 hours a day – sometimes even longer! – that is pretty remarkable. The reason that these batteries last such a long time, however, is because they are lacking in these extra features.

Why rechargeable batteries may be most beneficial for you

With traditional hearing aids, there is a trade-off: either less features with greater battery life or more features with less battery life. Some zinc air batteries will last only one or two days with certain high-performing hearing devices.

This extensive use of hearing aid batteries translates to an average 150 billion zinc hearing aid batteries being disposed of every year and can cost some users of hearing devices approximately $150 annually! In addition, these batteries are not environmentally friendly as they are not recyclable and, like any battery, run the risk of leakages spreading into water supplies.

All in all, we at Greentree Audiology wanted to find an alternative for our clients to ensure that the waste and expense produced by traditional batteries could be a nuisance of the past.

How did we do it? We offer our clients in St. Louis a range of rechargeable hearing aid options to choose from for your hearing devices.

Rechargeable batteries for your hearing devices: The options

The eCharger: Compatible with Siemens and Signia

Instead of replacing old batteries every 1-2 days, the Signia and Siemens rechargeable hearing instruments only need one pair of rechargeable batteries each year.

The eCharger is offered by Sivantos Group, which is the parent company of Siemens and Signia. That means this rechargeable battery device is compatible with several hearing aids, including Motion (behind-the-ear) as well as Carat and Pure (receiver-in-canal devices).

The eCharger comes with a chamber, which you place your batteries into overnight (at least 6 hours), and it acts as both a charging portal as well as a dehumidifier!

Phonak Audeo B-R

Representing the first built-in lithium-ion rechargeable battery, the Audeo B-R is Phonak’s first hearing aid that comes equipped with a rechargeable battery system. As the battery is actually built-in, it lasts the lifetime of the hearing instrument, so users of this receiver-in-canal hearing device will no longer have any need for new batteries!

The Audeo B-R also boasts new features such as the Belong Processing Platform and the Phonak Charger Case (for more on these features, click here.

The batteries used by the Phonak Audeo B-R only need 30 minutes of charging, and then they are immediately good to go for up to 6 hours.

Starkey VFusion

The VFusion Rechargeable Battery System, produced by Starkey Hearing Technologies, will make you completely rethink the purpose of a USB stick.

Two VFusion batteries can be placed into a USB thumb drive, which can then be inserted into your computer – yes, your computer! – to produce hearing power of 18+ hours. It is truly revolutionary!

The VFusion Rechargeable Battery System costs $130 upfront, but considering Starkey hearing aid users will only need to purchase two rechargeable batteries annually, it is a great investment – not to mention incredibly convenient. The long-lasting nature of the batteries also provides confidence in wearing your hearing devices throughout the day. For more on Starkey hearing aids generally, visit our site.


Last but definitely not least, the zPower is an independent battery company, which means that it does not have an affiliation with any specific hearing aid manufacturer.

Although it requires that a new battery door is custom-fitted to your existing hearing instruments, these batteries last up to 24 hours on a single charge! zPower silver-zinc (AgZn) rechargeable batteries only need to be replaced once a year.
