Small Storage Batteries?

I’m told that there’s a recipe for it in the book “What’s a Transistor?” and I’ve read the entire thing, gotten all the recipes, and not only can I not discover the solar panel recipe - despite having 7 fabrication and 6 electronics - there is no small storage battery recipe at all.

What do? :frowning:

You can no longer make them because they are considered too complex to make by hand.

I swear I googled the issue a million different ways. Thank you so much ; w;
