Hearing aids contain a microphone, a receiver, and an amplifier. Many hearing aid models require the use of disposable, zinc-coated batteries. Newer hearing aid products are lightweight, possess a streamlined design, and rely upon batteries that can be recharged. If you are going to have your ears checked and there is a possibility that hearing aids will be prescribed, compare disposable and rechargeable hearing aid batteries.
Hearing Aids That Require Zinc-Coated Batteries
Round zinc-coated batteries are air-activated and contain a colored pull tab. The colored tab is dependent upon the battery size and shelf life. Once the tab is pulled from a battery, it will be activated. This battery style may last anywhere from a few days to a week.
Because it will take a wearer some time to get adjusted to changing out batteries and determining the average amount of time that one pair will last, it is a good idea to bring fresh batteries during occasions when time will be spent away from home. A small pouch or case can be used to transport spare batteries. Many hearing aids that require the use of disposable batteries are water-resistant, but not all models will be waterproof.
Hearing Aids That Require A Rechargeable Battery
A rechargeable battery will be enclosed in each hearing aid that is part of a set. The batteries will not need to be removed from the aids. Each recharging session will result in a pair of aids being operable for a full day. A charging station will need to be purchased separately and the aids can be docked on it at the end of each day.
A recharge will take a few hours to complete. Even if a battery is not fully drained, it can be placed on the charging station. This will ensure that the batteries are powered up completely. A recharging station will need to be plugged into a standard wall outlet. If a hearing aid wearer will be staying away from their home overnight, they will need to bring their charging station with them.
A charging station may come with a zippered bag or a special carrying case that will keep the electrical cords and charger dry. Just like models that require the use of disposable batteries, hearing aids that require rechargeable batteries may be water-resistant, but not waterproof. Many rechargeable models are small in size and need to be pressed all of the way into the ear canal.
