You probably meant to say current times time is total charge.

Yeah, probably something like that. ;-) Actually, what I meant to
write was more like:
-- total energy needed = voltage * sum of (each current times the
length
of time that current is drawn.

Lesseee...unit analysis...volts * amps * time. OK, that looks better.

Thanks, Jim.
