Hi, you're in the right place, because I can help you. Replacing the battery in a device is very easy. If you take a laptop as an example, all you have to do is take the back cover off and if I'm not mistaken, you'll see the little battery right away. Before writing you this answer I checked the information on https://electronicshacks.com/cr2016-...032-batteries/ . And yes, I think I described it quite clearly, but if you need more information, you can check it on that site for details.
