no they store power, they don't make their own power.

It's impossible to "store power". Power cannot be stored. Do you mean
store energy?

if a battery isn't
charged it won't do anything but take up space.

If a battery has a chemical potential sufficient enough to generate (ie.
produce) an electrical potential, then it will produce power when a load
is
connected.

semantics but I see your point.

but how can a batt. create it's own power?? the argument was that it can
create it's own power, without an alt, if the alt doesn't charge it up it'll
be some chemicals and plastic.
