It doesn't really apply in this case. The battery is 4 cells, giving 6 volts tapped at 3 for the carbon microphone (it's basically a field telephone with added bells and whistles (well, in this case a keying relay and some extra switchery)).
The 6 volts is used to operate the keying relay at the 'local' (to the set) end, and extra cells can be added if the line circuit has too much resistance for it to operate reliably.
