Thank you for a concise and accurate guide. The pictures were clear and the circles and arrows helped locate all the screws, even that one next to the battery connector. Total time was about half an hour because I also did some cleaning to get rid of about three years worth of gunk.

The battery model number on my original is C31N1602. Rated at 11.55 V 57Wh, min 4800 Ah. Hope that helps anyone. I bought a replacement for about $50.
