more straightforward circuit without needing to be either
placed opposite each other or have an extra bit of wiring
to loop the current round. It would mean they were less
likely to become dislodged, make a simpler circuit,
meaning less wiring, and easier to remove and insert
without disturbing the other batteries one has just

batteries forming the sides and conductive terminals at the
