I'm talking about two 12v batteries in a series circuit meaning one

positive pole connected

to the negative pole of the other battery. The left over positive and

negative poles must be

connected to some sort of circuit and load such as a light bulb or

electronic gadget that will

cause current to flow through the entire circuit.


In such a circuit, neither battery will charge the other, they will
only be
discharged together through the load.
The same current will flow through both batteries, and in both
batteries you
can regard the current as "flowing out" of the positive pole.

To charge a battery, current must be flowing "into" the positive pole,
which
can only happen if you connect two batteries in parallel, where one is
more
discharged than the other.

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.

Let's see, +16v from the solar panel to the +12.7v on the battery. -
from the solar panel connected to - on the battery. 10 amps or current
is flowing. Which way through the battery is the current? If the current
is not flowing through the battery, where is it going?
