Darren,

  OK, now the 4 volts makes some sense. Presuming three mercury cells at 1.35 volts would yield ~4 volts. No thanks on the replacements. I just like the way this tiny shirtpocket radio displays (and it has the Nipper logo molded onto the back).

I though it was the fish that gave us mercury...
