How do people log battery performance data for those scientific looking charts in reviews and YouTube videos?
2026-03-20 00:53 UTC
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.

Yes you need a specific battery tester. Here is a Video explaining how to test batteries: [How to Properly Test New and Used Li-Ion Batteries (Including Cool Testers)](https://youtu.be/Dwpb5N0Ov5w)(15:12) by Andreas Spiess At 6:14 he recommends a few testers. The more expensive ones list connection options via cable and Bluetooth.
