Would this just be a full wave bridge rectifier?
I used to do that (4 diodes) for batteries AND powersupplies when I built my own guitar effects board power source. I was tired of either putting things in the wrong way and either a) not working or b) frying some electrolytic capacitor (if was a high current supply).

Seriously - is it just that or did they find a way to make it have low enough resistance to put in every device ?
- wrs 16y agoIt's purely mechanical (look at the diagram). The contacts are shaped so the battery hits the right part depending on which end it is.
- mhb 16y agoIt would be if you don't RTFA.
- michaelneale 16y agoYes i probably should have. But I am annoyed that I have broken enough electronics that rectifiers weren't always part of it (but that is unrelated to batteries). Fwiw in the apple magic mouse you can only mechanically out them in one way.
- mhb 16y agoBesides the advantage of being passive and cheap, this solution also avoids the voltage drop of diodes.
