According to a May 2020 survey, ownership of rechargeable hearing aids rose to 30% from 11% four years ago. As the sound quality, battery efficiency and interchangeability, and cosmetic appeal continue to improve, rechargeable hearing aids are becoming an inevitable trend for the future. However, users of disposable hearing aids are currently more concerned about rechargeable battery life and the ease of charging. So what batteries are used in rechargeable hearing aids? Today Grepow will tell the battery which used in rechargeable hearing aids and its advantanges.

What batteries are used in rechargeable hearing aids?

Rechargeable hearing aid battery shape is mostly button type. The battery material of it can be divided into nickel-hydrogen rechargeable batteries, silver-zinc rechargeable batteries, and lithium-ion rechargeable batteries (Li-ion rechargeable batteries) three categories which are built-in batteries and almost non-removable.

The first hearing aid with a built-in lithium-ion rechargeable battery was launched in 2016. In the context of the improvement of lithium-ion battery technology and energy density, lithium battery technology has become the first choice in almost all consumer electronics with many advantages. Since steel-cased button batteries can more perfectly fit the space size and structure of the rechargeable hearing aid charging compartment, they are now the battery of choice for rechargeable hearing aid batteries. So what are the advantages of using steel-cased button batteries for rechargeable hearing aids?

Advantages of using steel-cased button batteries for rechargeable hearing aids

1. Super battery life

Compared with non-rechargeable hearing aid batteries can only be used for a few days, rechargeable hearing aid super battery life in daily use should not be underestimated, a full charge can support 61 hours, enough for 4 days even more. Though in a complex environment, the use of Bluetooth connection and tracking, etc., users do not have to worry about the power.

2. Fast full charge

High capacity, fast charging! A completely dead hearing aid can regain full power after about 4 hours of charging. When you go to bed every night, you can charge your hearing aid to ensure a full charge for the next day.

3. Fast charging technology

Fast charging capability, support 3C fast charging, fast charging function is the savior of the unexpected situation. It takes only 15 minutes to charge 75%, 17 min to 80% power, 20 min to 85%. Don’t need to replace the battery, easy to deal with emergencies.

4. Long service life

Compared with a few days or half a month to worry about the dead disposable batteries, rechargeable lithium-ion batteries have a longer service life, generally speaking, can be used for 4-5 years.

5. Portable charging technology

Portable charger technology makes charging more hassle-free. Just like TWS headphones charging, rechargeable hearing aids can get additional runtime with the charging case. What we need to do is just to put the hearing aids into the charging box and keep the case at full power. After a full charge for hearing aids range of power, enough to cope with a say-go short trip around.

6. Energy saving and environmental protection

Ordinary zinc-air batteries need to be separated from garbage and are difficult to recycle, while rechargeable lithium batteries last longer and can be recharged repeatedly, which is energy-saving and environmental protection.

7. No need to replace batteries frequently

Replacing the button battery of a disposable hearing aid

For the elderly with inflexible hands or a visual impairment, frequent battery replacement is undoubtedly one of the obstacles to using hearing aids. Hearing aids using rechargeable button cells can avoid the trouble of frequent battery replacement, making the use of hearing aids more convenient.

8. Avoid children from swallowing the battery by mistake

The battery of the rechargeable hearing aid remains sealed, even if the whole hearing aid is swallowed by children or pets by mistake, the hearing aid shell can well prevent it from contacting human tissue.

In short, with the continuous progress and development of science, the future of rechargeable hearing aids will be more exciting with the support of a more powerful range, long service life, and fast charging steel-cased buckle lithium-ion batteries!
