Well rebelscum includes pictures of the instruction sheets in their photo reviews of star wars figures, so I don't think it would be too bad if a picture of the battery locations and types were uploaded somewhere. As long as the "save as" function is disabled I would think it would be ok. There was another figure site I found that had crisp scans of Star Wars instruction sheets when I was building an EP3 Anakin from loose parts ( as at the time it was cheaper than trying to buy the figure whole), but it prevented you from saving the scans. I even went into the code and could not get to the full-size image file, just the small thumbnail. 'A thought, not sure if this will breach copyright, but it would be awesome if we had a database of all of the instruction sheets. At the very least, what batteries go with what figures.
Or I guess the simpler thing to do would be to make a thread with lists of each armor and what batteries it takes and where they go on the figure.
