For example, I came across this YouTube video in which the author tests a whole bunch of batteries and displays a series of bar charts showing each battery's performance in various categories. How do content creators capture and log battery output like that? Is there a specific tool that plugs into a PC or records to a MicroSD card or something?

"Data Logging Battery Tester" is the phrase to search for. I don't see anything off the shelf, but I see other discussions about the topic on the internet in general.
