Then there were the pocket lamp batteries 4.5 v with brass strips

and the 3v cycle lamp batteries with one on top and one on the side

People seem to be making lash-ups for those, so probably obsolete.

and the lantern batteries with the springs on the top often used by
schoolchildren with wire wool to start a fire. grin.

I have a moderately new torch that uses one of those. They are readily
available. You can also get rechargeable ones, and my torch has a hole
(filled with a rubber plug) so that it can be charged in situ.

Do you remember those big 1.5 cells used for lighting the gas?

Yes. I think it's all piezo these days.
