But if anyone has anything to add that might help explain this to this ignorant person, I'd be happy for additional lessons. Thanks again to you, MarkHaysHarris777. I do appreciate your post. It did explain some of the puzzle.
I haven't bought the pine64 battery holder myself, but according to a discussion that was going on over in this thread about the RTC battery holder, it appears that for starters, the battery holder markings are wrong (if they were right, no more instructions would be needed!) In that thread, the guys indicated that the batteries should both be placed in the holder positive (+) side down. There was also mention that if you had dud, or counterfeit batteries, you could get the expected 3v from the battery if you had one + up and one + down.
Unless you can test with a multimeter, it's all just guessing from here in. You could be unlucky and have dud batteries or a mis-wired connector... is the red wire on the same side of both connectors? And is it or the black wire connected to the same place in the two different holders? There is such a thing as positive polarity, and negative polarity (with respect to ground - polarity is only negative or positive with respect to some reference), but you'll encounter mostly positive stuff in everyday electronics. One way you can check the batteries if you have a LED handy is to fit batter between the leads of an led and see if it lights up - if the LED lights up with the long lead on the positive (+) side of the battery, that battery is fine (the polarity is correct and it isn't flat).
