Hearing Aid Batteries

Flynn Associates knows there are many factors to consider when recommending hearing aids. This includes limits on the patient’s dexterity or vision or an active lifestyle. In these instances, we may recommend devices with rechargeable batteries. In other instances, we may recommend technology powered by replaceable batteries. Either way, we’ve got your battery needs covered.

Disposable battery sizes

Different hearing aids are powered by different size batteries. How long your batteries last will depend on the number of features you use and the size of the battery. Your hearing aid may have an app that lets you monitor your battery level. Some hearing aids make a chirping sound when the battery is reaching the end of its useful life. It’s easy to shop for hearing aid batteries. Each battery has a numeric code and a color to make identification easy. The four most common hearing aid battery sizes are:

  • Orange (#13) for behind the ear and in the ear instruments. They can last up to 240 hours
  • Brown (#312) is the smallest battery available and is used for in-the-canal (ITC) and completely-in-canal (CIC) devices. It can last up to 175 hours
  • Yellow (#10) batteries are used in small hearing aids like ITC and CIC models. However, this battery has a shorter life at about 80 hours
  • Blue (#675) is the largest battery, and it has the longest life. This size is used to power bigger hearing aids like behind-the-ear (BTE) devices. Blue batteries can last as long as 300 hours

Rechargeable batteries

Rechargeable batteries give you freedom from battery changes. This hearing aid option includes a docking station for recharging the battery. How long the battery lasts between charges depends on the functions and features you use. Some hearing aids with rechargeable batteries can also operate with disposable batteries in an emergency.

Even some rechargeable batteries must be replaced every few years. When its time, trust Flynn Associates to have the batteries you need.

Extending hearing aid battery life

Get the longest life from your battery. Follow these guidelines for handling and storing your batteries.

  • Wait at least two minutes after pulling the tab on a new battery before installing in the hearing aid
  • Keep hearing aids dry. Exposure to moisture reduces the life of your batteries
  • Always store your hearing aids with the battery door open

Store your hearing aids and extra batteries in a cool and dry place
