Robert,

my understanding is that most Enigma machines used a 4.5 volt battery 
which contained three zinc carbon dry cells connected in series.

The one Naval Enigma I have seen had a pair of terminals which were 
labelled 4 volts (such as would be produced by two lead-acid cells in 
series).  I presume these were used when the Enigma was permanently 
installed on board a ship.

The lamps were nominally rated at 3.5 volts.

Julian.
