[time-nuts] Lead acid battery noise levels

[Eric Williams]

I wonder if lithium batteries would have a good noise figure.  The
nano-structure of the electrodes give them very large surface area and low
resistance, but the charge carriers are different than other types of
chemistry and I don't know if that's good or bad.
