the magic of mass production

 

could be true but am surprised they are not hard soldered together

 

those 6v lantern batteries are not that common or cheap in nz

 

so don't be surprised if you cut 1 open, even the same type, and find it's made of a bundle of other sized batteries hard soldered together....

They _are_ constructed of smaller cells; 4 big 1.5v units.

Ideally, there'd just be one big cell, but there need to be 4 because the electrochemistry dictates that each cell will produce 1.5V.

To get 6V you must string 4 in series.

If you think about it, using 32 AAs would be extremely wasteful as the ratio of electrolyte to packaging drops with the diameter of the cell...
