Modern hearing aids come in different styles designed to address a wide variety of needs. Some hearing aids do not require batteries. If you are concerned about moving around with spare batteries and the cost of replacing batteries now and then, you should try rechargeable hearing aids.
Instead of replacing the batteries, you only have to recharge the batteries for a few minutes. The batteries can last for several hours without a recharge. Here are some top benefits of rechargeable hearing aids.
They Don't Get Drained Easily
Most hearing aids are powered by zinc-air batteries. These batteries are activated with oxygen. Therefore, when the sticker is removed, the battery starts to drain even when the batteries are not being used. This means in a few days; the battery will be completely drained.
Rechargeable hearing aids use lithium-ion batteries. These batteries do not lose their charge like zinc-air batteries. Lithium-ion batteries can provide enough power for a whole day of continuous use.
You Don't Have to Compromise on Features
The ability to stream movies, music and to respond to calls wirelessly through Bluetooth has significantly transformed hearing aid technology. However, Bluetooth can take a toll on the batteries of your hearing aids. For example, zinc-air batteries can last through the week if you use hearing aids that do not support Bluetooth. However, for hearing aids with Bluetooth features, your hearing aids will last a few days.
This means you are faced with the decision of using aids that do not have Bluetooth to save on battery consumption or using Bluetooth-enabled hearing aids and budget for changing batteries often. With rechargeable hearing aid batteries, you do not have to compromise on features such as Bluetooth. You can stream music and movies and still use the hearing aids for several hours.
Better Performance in Cold Weather
The chemical reaction required for batteries to operate is slowed down in cool temperatures. This means a battery used in cold conditions emits less current compared to when working at higher temperatures. Zinc-air batteries do not do well in cold weather. Low temperature and lack of moisture drain the batteries quickly, which, as a result, drains your hearing aids and affects sound quality.
Rechargeable hearing aids work better in cold weather. With rechargeable hearing aids, there is minimal loss of battery power. Rechargeable hearing aids are becoming popular in areas with extreme winter conditions because they are easier to use and cost-effective.
