Unless a battery has an internal short almost all batteries will show full
voltage without a load. The open circuit voltage tells almost nothing
unless the battery is totally bad or dead.

I agree that, unless one or more cells are shorted, or if the battery
will no longer take any charge whatsoever, an open circuit no-load voltage
test with a DMM won't tell you much.

That is exactly why I brought it to them, to test under load for
at least 10 or 15 minutes.

It tested GOOD. They would have failed it if it tested bad, as they
printed a copy of the test report, so, it clearly was in the lower
range of good.
