Batteries

As has been discussed before, the superbatteries in the MT
Referee's Manual are much too expensive for use in anything
larger than a robot.  But we know that, in the real world,
diesel-electric submarines run for long periods on batteries, and
that electric cars, running on batteries, are expected to become
generally available within a few years.

Has anyone a table, for use in Traveller, of price and storage
capacity for large-capacity batteries such as these applications
would require?  If no one has one, can someone generate one?  We
could make the improvement per tech level proportional to the one
for superbatteries, but we need a value to begin with, and I have
no idea what an appropriate value would be.
