The lifespan of a hearing aid battery can vary depending on a number of factors, including the type of battery, the size of the battery, and the amount of use the hearing aid receives.
On average, a zinc-air hearing aid battery can last anywhere from 3 to 14 days depending on usage. Rechargeable batteries last longer, depending on the battery capacity, usage and charging method.
It’s also important to note that manufacturers will provide the estimate of battery life in hours of usage, which can be helpful when comparing the battery life of different hearing aids.
It’s also important to keep in mind that some hearing aids have a power-saving feature that automatically turns off the hearing aid when it is not in use, which can help extend the battery life.
It’s important to check the manufacturer’s instructions for your specific hearing aid to get an accurate estimate of battery life.
