Hi Peter,

I'm sure that the batteries should be 2 x 1.5V = 3V.
First, the memory is fed with whichever is higher out of the battery and the
5V power rail - if the battery was 6V then it would supply the memory ALL
the time, until the battery was discharged!
Secondly, the battery low indicator has a threshold of 1.9V - far too low
for a 6V pack.

Hope this helps!
