The easiest way to test a hearing aid battery is to use a hearing aid battery tester. Testers are inexpensive accessories that you purchase from your hearing specialist, electronics stores or online. How often do I need to change the batteries in my hearing aids? How often you need to change your hearing aid batteries depends on the size of the hearing aid battery (e.g., size 10 is smaller than size 675) and how often you use your hearing aid. But, generally speaking, you can expect to change your batteries every 5 to 10 days. Does turning off your hearing aid when you're not using it prolong its battery life? Turning off your hearing aid when you're not wearing it will certainly prolong the life of your battery. It is not possible to accurately predict how long a battery will last because there are so many variables. For example, the size of the hearing aid battery and the level of hearing loss one has - mild, moderate, or profound - will affect battery life. Your hearing specialist should be able to give you an indication of the life of the battery using this information.
