One thing about the Booster knob and the battery button not lining up - the threads on every battery are different, so you
will find that the orientation is different for each battery. This is why the knob and button don't line up, because its pretty
much impossible to get them to line up for every battery with the difference in the battery threads.
You will find the odd battery that lines up perfectly, though, it is of course completely random. So when you find one that lines
up, enjoy and treasure it!
