Case analyzer just does the thermal properties, which I find helps but imo internal resistance is much more important. I can't check it now bc of the new wires but I remember it was very high. If you end up getting enough dna devices, the little copper plug does come in handy, but you can always short out the 510 and get the same results. For some reason very few of the Chinese companies set internal resistance or run case analyzer. Which irks me... whatever but come on all they had to do was run it on one device, and plug those numbers in every one after that.
Cool thanks that helped a lot, yeah some of my new wiring was keeping me from pushing all the way down. As to your question, I'm pretty sure the screws were it, the 510 assemble has to come loose and then i remember it did take some pulling to get it free though, that bit is in there very tight. Sorry I'm not so good on short term memory... If you can't tell :/
Edit, Btw did you shrink wrap that batt yourself? If so what'd you use? I've been wanting to do that to a few of my Samsungs that've gotten chewed up somehow.
