How Long Do Hearing Aid Batteries Last?
Nowadays, people with disabilities no longer have to worry about the inconveniences that come along with their conditions. Aside from the fact that they are strongly supported and respected by the community, they now can invest in things that can help them. It is amazing to know how the deaf can hear using hearing aids. However, these devices need a battery to work. The question is: “How long do hearing aid batteries last?”
How Do Hearing Aids Function?
A hearing aid is a small electronic device that is worn inside or behind your ears. They are not so visible, making it nearly impossible when worn. This device receives sound through a microphone converting the sound waves to electrical signals and sends them to an amplifier. The amplifier then sends them to the ear through a speaker. The most popular hearing aid style comes in the form of behind-the-ear hearing aid with receiver-in-canal (RIC). This device is classified as a medical device in most countries as it improves hearing by making a sound audible to a person with hearing ability is not normal.
The most basic and vital component of any hearing aid is its battery. Hearing aids won’t work without it. Some hearing aids use zinc-air cells, which are powered by oxygen, but a few use mercury batteries. Most commonly, the size of the hearing aid dictates how long a battery will last. On average, smaller batteries work for three to five days, while larger hearing aids have bigger batteries, which can last for two weeks.
Hearing aids, which are dependent on batteries, should serve its purpose and work well if you know how long do hearing aid batteries last. Now, how long do hearing aid batteries last? It differs from its brands and sizes.
Manufacturers of hearing aid have been providing information about their products’ battery usage that covers the technical specifications of each hearing aid product.
Estimated Battery Life Of Hearing Aids
The battery life of hearing aid typically lasts between 3-7 days. How long do hearing aid batteries last depends on different factors such as the type and size of the hearing device, the type and size of its battery, and even on how you use it.
Usually, it should be easy to estimate the anticipated battery life of the hearing aid. Most commonly, a size 312 battery has a capacity of 145 milli-Amp-hours (mAh), an estimated battery life of 111.5 hours.
Surveys show that the average receiver-in-canal (RIC) hearing aid user accounts for a total of 76 hours of the total time use per battery. Considering that the average hearing aid user reports using their hearing aids at about 13 hours per day, this would give an expected battery life of 5.8 days.
Estimating your battery life of hearing aids is not so easy. But hearing aid manufacturers provide estimates as to how long do hearing aid batteries last along with their products.
But users must also be aware that manufacturers often overestimate the battery life of their hearing aids because of some factors to consider, such as the user’s lifestyle, hearing aid’s configuration, and whether wireless streaming is used. It is sometimes hard to estimate battery life on your own until you try the hearing aids yourself.
Manufacturer estimates are also not standardized in some instances. Some hearing aid manufacturers use a higher capacity (mAh) battery, leading to an overstated estimate compared to a manufacturer that uses a standard capacity battery of the same size.
The size of the battery also matters. The most popular and commonly used hearing aid battery by far is the size 312 battery because it offers the right balance between size and battery life. It provides a relatively small size with more battery life compared to a size 10 battery.
In most surveys, hearing aid batteries last the longest in power behind-the-ear (BTE-P) hearing aids and the shortest in invisible-in-canal (IIC) hearing aids. This information is apparently because smaller hearing aids like the IIC use smaller batteries, which carry lower mAh capacity.
How you use your hearing aid on a typical day is also an essential factor to consider. Habitually, a regular user is wearing and using his hearing aids around 13 hours per day and receives just almost six days' worth of power before having to change their batteries.
Even streaming audio to hearing aids from your phone, television, or any other device affects the battery life of your hearing aid. Those who reported using wireless streaming have received eight hours less than those who are not streaming, on the average.
Hearing aids can be life-changing. They are beneficial to people who rely on hearing assistance to participate in social interaction. This small electronic device that amplifies sound can help bring back many of the sounds that hearing-impaired people are missing. This is a tool for survival, and you need to take note of how long do hearing aid batteries last to make full use of it.
