My battery had not been holding its charge and would sometimes just die even though it had 11% left and sometimes it would die and then suddenly have 10% battery out of nowhere.
Everything went really well and the instructions were very well detailed and very useful. I only had one glitch and that was when I was inserting the new battery and it wasn't really fitting nicely but thankfully it went in right and the connectors lined right up.
Watch what you do with the camera securing piece it's easy to loose and confusing if you missed what that was and suddenly saw a little metal piece just sitting there. I know it freaked me out but I eventually saw what it was for.
