Hearing aids need a quality steady power supply from quality hearing aid batteries in order to work correctly. Usually a standard battery will last between 5-21 days.

The life of a disposable battery depends on hearing aid type, battery capacity, and how much the hearing aid is used.

There are also rechargeable hearing aids. They come with their own charger, and a 3 hour charge will give you 24 hours of hearing performance. For many patients with visual problems or arthritis, handling small batteries can be difficult. Rechargeable hearing aids are a great option for them. They are easy to manage. At night-time all you do is plug your hearing aids in your charger, and they will be charged and ready for you in the morning.
