Before shipping this one off to the "happy charger
grounds in the sky", I opened it up to see how "smart"
it really was.

As external examination of performance suggested, this is a current
limited, voltage limited power supply set for 13.4 volts at about 0.6
amps.
Fine for long term storage of charged batteries but not up to the
task of topping off a dead battery.

Hi Bob,
Notice on the last picture with the heat sink removed there is an area labeled VR1. The earlier versions had a pot there that one could adjust for the optimum maintainer voltage. [13.8 is what I use] The circuit board is still drilled for a pot on the ones I've purchased recently.
I purchased a handful of 100 pots that I install to maintain that flexibility. I have a dozen or so of the earlier versions and I'd guess 80% had to be touched up..some were low some were high.
I've had 2-3 fail and at least two of them failed at the transformer to 110VAC plug connection. I was able to repair those. One failed for some other reason and I just kept it for parts. Further investigation wasn't worth the $time$.
I fully agree that they are OK for long term storage but not charging.
Thanks for taking the time to run the tests! Earl
