I Tested 3 AA Batteries So You Don't Have To

In this video, I compare zinc-carbon, alkaline and lithium AA batteries using real measurements. I test: • open-circuit voltage • voltage under load • internal resistance • capacity (Ah) • delivered energy (Wh) • energy per dollar All batteries were tested using the same methodology and discharge conditions.
