The MAGNEVOLT Model 308 battery is a two section
unit containing 7 cells in the main
voltage section and a single cell in the timer
section. The main section operates under
a load of 22.2 ohms at a nominal discharge rate of
approximately 0.477 amps. The timer
cell section operates under a load of 11.1 ohms at
the one hour rate of 30.9 ohms at the
three hour rate. Nominal discharge rates are 0.135
amps and 0.485 amps at the one and
three hour rates respectively.
