Hey everyone,
I am a big fan of AvE.
I watched the video
. He explained the theory of lead acid battery very well, but when said
" A POSITIVE ANODE, NEGATIVE in CATHODE"

that trigged me, because
anode act as negative terminal in a
galvanic cell and
cathode acts as positive terminal.Anode acts as Oxidation electrode where electrons lost by Pb to the circuit, returning to the cathode where they are gained by PbO
2.
He made this mistake by refering to "DON'T PANIC". Which is only right for a
electrolytic cell .
This post is not made to criticize the mistake, but there is a lot of wrong literature in the internet regarding the topic.
