Thanks Rob that explains some of my anger in my youth.
The expensive NiFe dry cells I purchased were no better than Nicad's with the same bad habits.
I've read up on Nickel Iron Batteries and it's a shame they seem to be all but lost to history.
It is indeed a bit difficult to find I will change that in future to be more easy.
It is a pdf file to be downloaded, but the link is somewhere in the text and only visible because it is blue.
This should help https://www.wdnorton.nl/Electrical_equipment_page/Article%20Nife%20C105%20issue%202.pdf
But be aware, this still is the old version in which I made the incorrect remark that Lucas C105 Nife was a Nickel Iron battery instead of a Nickel Cadmium battery.
I will send you the correction I wrote for the VMCC by mail.
