Size 13 batteries are most commonly found in behind the ear (BTE) and in the ear (ITE) hearing aids. They are 7.9mm x 5.4mm in size and use an orange colour code. These batteries have a lifespan of approximately 6-14 days.
While there aren’t any foolproof ways to extend non-rechargeable battery life, these tips will ensure the power isn’t being wasted.
Turn the hearing devices off when not in use and leave the battery compartment door open overnight. Not only will this help keep battery power from being wasted, it will allow any moisture that has built up from the day's use to evaporate overnight.
To get optimal performance from your batteries, always store them at room temperature. Heat exposure and humid environments such as a bathroom will shorten battery life. Also, batteries shouldn’t be carried loose in pockets, a purse or a backpack where they might come into contact with other metal objects like coins or keys that can short-circuit the hearing aid batteries.
Common manufacturers of non-rechargeable hearing aid batteries include Rayovac and Energizer. However, many hearing aid manufacturers sell batteries wholesale to hearing care professionals, and the batteries may carry the brand name of that hearing aid manufacturer.
Another common practice is private labeling of batteries. This means the hearing care professional may purchase batteries wholesale and have them labeled with the name, address, phone number and logo associated with their office.
Regardless of the branding, most hearing aid batteries are made by trusted companies that produce other types of batteries for all types of electronics.
According to the National Capital Poison Control Center, more than 3,500 Americans of all ages swallow disposable button batteries every year. If this happens to a person or pet in your home, seek medical attention immediately.
