Why not just take the battery out of the 2nd one and put it in
parallel with the battery in the first one? It would be more
efficient.

It would be, but there's a catch. When the time comes to recharge the
now much bigger battery, the original charging circuit probably couldn't
handle the extra current. The greater the plate area, the more it starts
looking like a short circuit as far as the circuitry goes.

Most things being now built are made down to a cost instead of up to a
quality standard.
