 In this video, we will show you how to change the battery. To change a battery, you first need to open the battery drawer by using your nail and pulling down on the lip. Once the battery drawer is open, you need to flip the hearing aid over and poke the gap with a pen. You then get the new battery and remove it from the packaging. Peel the label which will expose the positive of the battery. The battery goes into the drawer with the positive side facing upwards. Allow the battery to sit in the battery drawer for a minute before you close the door. And close the battery drawer to turn the hearing aid on. And that's how you change your battery.
