Although rechargeable hearing aids have been available for more than 30 years, these products have had only sporadic success. This is a result of charging stations that are challenging to use. Old rechargeable hearing aids Singapore would only function for a limited amount of time if the device was positioned in a very certain way, which was problematic for users with dexterity challenges.
Previous versions of the rechargeable hearing aid also had limits in terms of perceived reliability, size, and circuitry. Most consumers have passed over rechargeable hearing aid batteries in favour of the conventional zinc-air batteries due to all of these possible limitations.
Modern technology, however, has fundamentally changed the sector and the way people with hearing loss perceive the world. Learn more about the development of rechargeable hearing aids and their batteries as well as their advantages by reading on.
The Evolution of the Rechargeable Hearing Aid Batteries
Rechargeable hearing aid batteries have significantly advanced over the past ten years. The nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) cell are two of the main possibilities.
Batteries with nickel-cadmium atoms
It has been established that NiCd cell batteries are less eco-friendly. Additionally, the batteries have what is known as a “memory effect.” The memory effect describes how batteries develop a “memory” of earlier periods of time before they are charged.
Batteries that exhibit this characteristic may eventually function worse. The battery may lose its ability to fully charge when recharged at half capacity. The ideal method for charging NiCd cell batteries is to totally discharge them before recharging them.
Batteries using nickel-metal hydride technology
The NiMH battery, according to the majority of experts, is a superior option for rechargeable hearing aids. The power offered by these batteries is almost two times that of NiCd batteries. These batteries are also free of cadmium, lead, mercury, and other harmful elements. NiMH cell batteries are hence far more environmentally friendly.
Benefits of the Rechargeable Hearing Aid Batteries
Digital hearing aids of today are more feature-rich and loaded with technology than ever before, including connection with mobile phones. These new features will, however, drastically reduce battery life and need frequent battery replacement for users.
The batteries need to be convenient, powerful, and user-friendly to provide hearing aid users with hearing loss with the best possible experience. These cutting-edge components are propelled by cutting-edge batteries that provide a number of startling advantages.
Superior Comfort & Ease of Use
There is no longer a need to deal with replacing tiny batteries thanks to the numerous technical advancements in hearing aids. This aspect is particularly beneficial for people with age-related health difficulties like Parkinson’s disease, dementia, dexterity problems, and arthritis.
Instead, you may simply charge the smartphone while you sleep by placing it on the charger. You will awaken in the morning with a recharged and revitalised tool for daily use.
Peace of Mind
The fear that the battery would run out at the worst time is a real one for many people who wear hearing aids. A faulty battery’s approaching possibility can be both upsetting and embarrassing.
You won’t have to worry about the device dying in the middle of the day if you charge your battery overnight. The best part is that users of rechargeable hearing aids won’t ever have to worry about where to install the battery.
Extended Shelf Life
Today’s rechargeable hearing aid batteries are almost universally supported by a sturdy, high-quality shield. This extra precaution prevents the battery from prematurely drying up or depleting.
The older versions of zinc-air batteries had a lot of issues like this. Rechargeable batteries also fare far better in tests that show how well they can survive adverse weather and harsh situations.
Lots of Flexibility
The restriction of only utilising rechargeable batteries is too great for some people. If you fit this description, many hearing aids come with zinc-air and rechargeable batteries. This improved adaptability provides essential backup power in situations where you might neglect to replenish the battery.
Environmentally friendly and green
Rechargeable hearing aid batteries are far more environmentally friendly than disposable ones when it comes to green, eco-friendly options. Any time a battery is disposed of, lead and acid that could be dangerous are released into the environment and into water supplies.
Two digital hearing aids can use up to 300 hearing aid batteries over the course of three years. However, throughout the same time period, two rechargeable hearing aids will only require an average of six rechargeable batteries.
