This should be proof enough that this is a myth. One AA sized battery is 1.5 volts. Put them in sequence, 32 AA batteries X 1.5V would be 48V. One large lantern battery is only 6 volts. This explains the 4 larger cells. They are 1.5V ea, adding up to the 6V.
I think I have replied correct,But I'll try to search more on this topic.
