The basics of Automotive Battery Load Testers.
We've talked about testing the voltage of your car's battery (Multimeters Part 3 -- vehicle battery and alternator voltage: th-cam.com/video/yeGm5Kj6sE0/w-d-xo.html), but sometimes the battery's voltage seems fine but it still won't start or is very slow to turn over -- this load tester will help identify when it's a battery problem (versus a problem with the starter or other car electronics.)
Super simple to use, just clip it onto your car's (or truck's or motorcycle's or golf kart's or whatever's) battery and click the button to see where the needle lands. That's it.
