> Did anyone really read the title thinking that the article was about alkaline batteries? I think not. Lithium-Ion were not in widespread use 30 years ago. So if we are just considering the price of Lithium-Ion, that would be the price from the first commercial product, which I expect was expensive for the time (it dropped in price around 30% in just a few years). I read the title and thought it was battery capacity/$, not Lithium-Ion specifically.
