This step almost finished me, and I did extensive damage to the battery plug. Fortunately, I later replaced the battery, and the replacement came with a new plug! :) Newbies need to know - 1. The battery plug is like a thin lip on a thicker lip, so you need to pry BETWEEN 2 thin lips to get it off, else you are trying to yank out the socket. 2. Mine was initially VERY tight, and trying to get it out broke the plastic on all sides of plug, even though I was as careful as possible. Luckily, this didn't hurt functionality and I later replaced the battery. AFTER disconnecting once, it was never so tight again,
