a). nuclear
No.  There were batteries long long before we learned
how to use nuclear energy.  Also, there is no danger of
exposure to radioactivity when you're working with a battery.

b). mechanical
No.  A battery has no moving parts.

c). gravitational
No.  No matter how high you take a battery in an airplane, or
how far you lower it into a mine-shaft, its characteristics don't
change.  In fact, batteries even work on things that are in orbit.

d). chemical
Bingo.
