There are several ways you can purchase hearing aid batteries. Often, drug stores or grocery stores will carry a small selection of hearing aid batteries. There are also options available for purchasing batteries online. Many people choose to purchase their hearing aid batteries from their local hearing center or audiology clinic. The benefit to purchasing them there is that you can be assured the batteries are fresh, as most hearing aid clinics rotate through their battery stock frequently. Also, if you forget what type you need, the professional staff can help you choose the right battery size. Ask your local clinic if they offer a battery club or other discount program, which can provide significant savings. They may also offer options for conveniently shipping the batteries directly to your home.
