I'm trying to find the dimensions of a 9V (PP3?) battery (no specific chemistry). For some reason it's giving me a lot of trouble. I've been able to find most of the information (I checked a bunch of sources and they've all got these same values):
However, I can't figure out the allowable range for the terminal diameters and depths. So my question is, what are the min/max values of these dimensions:
- M = min/max outer diameter of positive male terminal
- F = min/max inner diameter of negative female terminal
- H = min/max depth of negative female terminal
The min/max height of the positive male terminal I assume is linked to the female depth and also the 0.1mm - 2.1mm minimum range implied (A - D) by the first image above.
Also, there's the lip on the terminals to provide the snap action, so, that too.
