The battery on your car has an internal short?

The battery on you car has been discharged too far?

It's was almost as if the second battery lost nearly all its charge
to the flat battery.

Can someone explain what is happening with the battery charge
please.

QUESTION (2) If that's so then, to get the car started, is it
absolutely necessary to put a charger on the flat battery which is
in the car?

A lead-acid battery that has been run completely flat will never be
quite as good as it was before, but if it was in good shape before and
wasn't flat for too long, it should mostly recover.
