I once replaced a battery, not by breaking the device (ebook) in two, but by making a battery sized hole in the backplate. I knew approximately where the battery was and there was not much danger drilling in to the dead battery. Now, this idea was better than I thought. I could use bigger and fatter battery just by covering it with adhesive foil. And I could even use AA-shaped lithiums if the device thinness was not important. As regards to electrical connection, you use the connector and controller from the original battery and connect raw battery lines to the new battery of your choice. https://photos.app.goo.gl/YxjgaVVpiPvygHXS8 https://photos.app.goo.gl/YxjgaVVpiPvygHXS8
