Hello,
I've recently seen episode 1371 (yeh, I've been a bit busy and missed a few) and I learned about Lithium Thionyl Chloride batteries, which are perfect for a project I had in mind and I did not know about them.
Unfortunately I really wouldn't know how or where to find out about all of the battery chemistry and how to choose the perfect battery for a project.
This is not only to guarantee the best performance or the most economically advantageous solution for a single project, but it can also mean less waste, and less pollution.
I think this could be an awesome topic and I hope mighty Dave agrees.
Otherwise I'll post in beginners or some other board to see where to find documents to learn by myself.
Cheers
