Hearing aid batteries last anywhere between five and 14 days depending on the above factors. You will know it's time to replace your hearing aid batteries when the aids start beeping. One solution to save money and make batteries last longer is to purchase rechargeable batteries.
With built-in power there is no battery to handle or replace. With no charging contacts to alignâ just drop the hearing aid in and let the charger do the rest. The built-in power cell lasts for 24 hours on a single charge so that you can hear a better day, all day long.
