Sorry Naio, did not mean to confuse. This was just a different observation of battery charging compared to what I have observed a hundred or more times now with my adjustable voltage Meanwell and its attached watt/volt/amp meter/counter.
I had the Meanwell set to 14.45v when I plugged it into the over depleted starting battery which had measured 9.23v on my multimeter when the owner dropped it off to me.
I am used to seeing a 50% depleted battery just slowly climb toward 14.X at a solid 40 amps until battery voltage approached the my desired 14.x set voltage of the meanwell, and then amps would taper.
This over discharged 3 year old starting battery instantly rose to 14.45V and it only required 23 amps to get there. But after 30 seconds to a minute of slapping this battery upside its head, the voltage had dropped as the battery decided to stop resisting the meanwell's full available current. It was like removing all the hair and junk obscuring the drain on a sink.
I had heard about this behavior on an over discharged battery, I had just never witnessed it, and it was neat having the tools to watch it occur in real time.
I did notice the battery getting hot at 40 amps, and I wound up dialing the MW voltage all the way down( 13.12v) in an attempt to lessen the amperage. It worked, and the rapidly climbing battery temperature levelled off and began to drop, with a fan on it. I just came back every 15 to 20 minutes and kept bumping up the voltage little by little trying to keep it under 25 amps. Soon it was at 14.45v and I just held that Constant voltage, Absorption stage, for about 6 hours, unmonitored as Friday night occurred. It was only taking 1.23 amps after those 6 hours at 14.45v.
And I will stand by my opinion that one desires constant current limiting on overload, rather than automatic shut down until overload is removed, or hiccup mode on current overload.
But if one is only starting this Meanwell after another charging source has gotten the battery to absorption voltage for a while, then that works too.
I personally wanted an All in one charger, equalizer, and float voltage converter. I got sick of weighing the compromises when comparing/researching other charging sources. I love the MeanWell's freakish ability to bend any LA battery to my will. It cost me 127$ delivered, but I put another ~30$ into it with quieter additional fans, and 1K ohm 10 turn potentiometer, and solder and the Wattmeter inline on 8awg with 45 amp powerpole, was another 25$ or so.

Thanks Mex, for turning me onto the possibility of a Powersupply as an adjustable voltage, Kick burro manual charger.
