How long do hearing aid batteries last?

Batteries are crucial in ensuring your hearing aids will always be able to perform at their best for you. While you may consider the style, fit, technology level and cost of your hearing aids to be the priority, the quality of your hearing-aid battery is just as important. A good-quality battery that will last a good length of time will ensure your hearing aids work at optimum power and give you the chance to enjoy the benefits of your hearing aids without having to regularly replace or recharge the batteries.

Types of hearing aid batteries

There are two main types of hearing aid batteries:

Rechargeable batteries

Many of the newer hearing aids on the market come with rechargeable batteries. These are usually recharged overnight when you take your hearing aids out before bed. They are generally available for behind-the-ear (BTE) or Receiver in canal (RIC) hearing aids. There are also rechargeable hearing aids that can be placed in a charging cradle or plugged into a USB cable to charge overnight to provide a full day’s use.

Traditional disposable batteries
