How long do hearing aid batteries last?
The lifespan of hearing aid batteries depends on factors such as the type of hearing aid, the size of the battery, and how frequently the device is used. Generally, disposable zinc-air batteries, commonly used in hearing aids, last between 5 to 14 days. Larger batteries tend to have a longer lifespan than smaller ones. Factors such as the power demands of the hearing aid, environmental conditions, and the individual's hearing loss profile can influence battery life. Rechargeable hearing aids, on the other hand, typically last a full day on a single charge, with variations depending on usage patterns and technology features. It's essential to monitor battery levels regularly, follow the manufacturer's recommendations, and carry spare batteries if using disposable ones to ensure uninterrupted use of your hearing aids.
