Is your claim otherwise?

Connect the negative terminals of the batteries together.

Connect the positive terminals of the batteries together
through an ammeter. For the purposes of this experiment,
the batteries have exactly the same voltage so the ammeter
indicates that no current ever flows between the batteries.

Hi Keith,

You have admitted that energy dissipated in the loads cannot be
identified to its source and you have used the above devices previous
to that statement. Your admission dismisses their applicability.
Separability is not demonstrated.
