You are wrong. You cannot run current though a battery backwards. You
charge with a charging
source that has higher voltage than the battery and by wiring it so there
exists a complete
circuit.

When I connect my photovoltaic to my 12v battery the battery takes a
charge because the
photovoltaics operate at 16v at ten amps current. The 16v, being higher
than the 12v in the
batteries causes a chemical reaction to occur between the sponge lead and
the solid lead
and the acid electrolyte and electrons are stored The chemical reaction
reverses when the
photovoltaics are removed and a load placed upon the batteries and
electrons are released.
Current never goes backwards in the battery.

This is a common misconception and I'm very surprised so-called engineers
fall prey to it.

Say Capt'n, why don't you hook up an ampere meter in your circuit and tell
me what sign the reading has when charging and discharging. Or are going to
argue the principle of ammeters too?


Like I said in another post elsewhere, I'm not arguing with ammeter readings.
I AM saying, since an ammeter is connected in series external to the battery,
it tells you nothing about there being a circuit inside the battery. It only tells
you whether electrons flow into or out of the battery. There does not have
to be an internal circuit for electrons to flow. Chemical reactions take the place
of a circuit. These self-limiting chemical reactions change the composition of the
positive and negative plates; they do not conduct electricity.
