Having viewed the idiot piece on Youtube "32 AA cells" in a
lantern battery. I took apart a couple lantern batteries.
The Rayovac carbon had four D-like cells, and the Duracell
had literally four D cells (just like the D cells you'd buy
in the stores). With a cardboard spacer, and contacts.

Supposedly Energizer alkalines contain the F cells, not
Duracell. I havn't opened one of them. Also no clue what
happened to B, or E cells.
A simple 9 volt radio battery is all that is required for the memory
keep alive. Connect one to a cig ligther plug, with a diode to keep
the 12 volts from hitting the 9 volt battery, plug it into the lighter
socket, close the door, and change the battery. 7 volts is more than
enough to maintain the memory.
