I checked the 13 batteries I have using this battery tester.  It registers the 12ish volts as in the picture but then you press the load button for 10 seconds which puts a “cranking load” on the battery.  Not sure what the load is, but the machine gets very hot so its really pulling some current.  Anyway, if the needle stays in the green, the battery is ok.  They all checked out apart from one which i had not charged properly so was a bit flat.  I charged it, tested it again and it was ok.  I picked 8 that seemed to hold the needle up the highest for the 10 second load.
