I agree with Ando. The noise would be feedback from the motor brushes. Batteries don't supply a noisy voltage. Regulator circuits usually have caps on the input and output because they are regulating a rectified AC voltage. The caps filter out the ripple effect.

If electricity comes from electrons.. Where does morality come from?
