Taking the back off is not that difficult. I used a credit card to pry the back off by inserting and working around until it loosens up and off. Identifying the battery is another matter. There are two square plates (appx 31/2”x 5”) covered with white plastic. One showing part number and date, the other blank. The one with part # also shows a + and — which I assume could be the battery. I googled the image of the replacement battery for the tablet and the markings are shown differently than the part I described above. Also there's no visible detachable plug connector. I really can't be certain if what I am seeing is a battery. Maybe somebody reading this can help.
