Heh, heh.  Many years ago when radios had tubes in them and God wore 
tennis shoes, there were different voltage batteries in common form 
factor sizes.

One of them was a 90 volt "B" battery to provide the plate voltage in 
portable radios.  It was the shape of a 9 volt battery but about three 
times as long.

My cousin had seen me lick batteries to see if they were any good.  He 
picked up a 90 volt battery that I had and licked it.

His eyes lit up and he threw it across the room!  Then he screamed at me 
about how could I stand to lick them?  Fortunately they didn't have much 
amperage capacity.

They also came in 45 volt and 67-1/2 volt sizes as well.

Just FYI, A batteries provided filament voltages, B batteries were for 
plate voltages, and C batteries were for grid voltages.

Geez, am I really that old?  Hint:  I starting playing with electronics 
in the mid 1950's. ;-)
