    Battery charging: Minimum voltage differential?

    "Are you expecting some sort of 'threshold' condition for the voltage difference, for current to flow? The simple model we use, with an Internal Resistance would suggest not." Exactly. I don't see how there cannot be some kind of threshold voltage difference, below which charging does not...

    Battery charging: Minimum voltage differential?

    Thanks, but this case is not quite parallel enough, pun intended, to answer what I'm asking. Batteries in parallel are all discharging, and the effect of one battery set up to charge another may result in a more subtle state than two or more batteries that are all discharging. The internal...

    Battery charging: Minimum voltage differential?

    I have a question that I believe requires knowledge on the graduate level, but I can't necessarily express it in terms more complicated than plain English. If this is not so, moderator, please adjust to your taste, and thank you! If it helps to know this, I'm an audio/video systems designer and...

I am an audio/video system designer and installer with a bent toward problem solving and clear expression of ideas, especially when asking technical questions. Maybe that's why my question is picky. Anyway, I think it will be...
