Use the nylon spudger to pry the battery from the back of the screen. Work your way around the edges, similar to opening the casing. The adhesive used to hold the battery down is very strong. Don't be afraid to use some force. The adhesive used to hold the battery down is very strong. Don't be afraid to use some force.

We're can I get a battery? And I don't think the part should have died in less than a year . The battery lasted less than 6 mos. I bought the tablet for my mom to play cards on and that's it .She doesn't go on line. I put a book on it before I gave it to her and that is it. She doesn't even use it every day . What's the deal?
