THE BEST batteries?

Ditto on the Eneloops......

For a while someone was selling a kit of one battery, and a fake
battery for the other slot. I can't find that now. You can make
one yourself from a piece of wood about .5 inch diameter, 2 copper
screws, a piece of wire and some electrical tape.

Or take a very dead battery and solder a wire around the ends.
(may leak acid over a very long time period)

This is not the one i was thinking of, but works
Battery Adapter Kit - Convert AA & AAA to C & D size
take the smallest one, open it, solder a wire to each of the
terminals...

Heheh, I have a Sanyo Eneloop set I bought from Costco that has those C and D adapters. They actually work in a pinch. They hardly last at all that way of course when they work.

I use dummy cells and spacers for my Pila IBS charger for my RCR123 cells. And an adapter made from a delrin rod with brass screws at the ends wired to a C cell battery carrier to charge my C sized Li-Ion batteries.

I would definitely avoid putting any lithium chemisty cells in series that are not close to equal level of capacity. Parasitic charging can occur and cause one to go off like a road flare. Pretty much how battery packs like the laptop batteries that have gone poof, flash.

A dummy cell out of metal is a better plan.
