Thanks. I think I found a good option.

These are flat heads. Both batteries come with the metal tab already soldered to negative. I would bend the tab out on one (they have a picture of the folded metal tab in the 5th photo). I could leave it bent out and it would still insert into the charger. So would not have to keep bending it back and forth.

Inserting it into the 34c would work fine as the tight fit would cause the other battery to contact.

So insertion would be

Top battery. Negative (leave tab bent in or remove) ———-positive
Bottom battery. Positive——————————————————negative (bend tab out)
