Question: is it fun making batteries

I don’t do batteries myself, what I do is study them to better understand how they work. I find it quite fun, but that’s quite a personal thing and not only related to batteries. I would say that, in general, I find fun to study things and processes to understand how they work and how to improve them. For example, last week I went to a workshop were we used mathematics to better understand how contact lenses are made.
