'Smart' charger fail.
Neighbor's group 27 truck starting battery was drained dead inadvertently. It's on its final stages anyway as it was jumped 2x in the last month, mostly short trip driven, never plugged in, and is li...

I was not trying to equalize the battery. I had not removed the ground cable. 15.79v at 14 amps is extremely abusive to a 100Ah battery.
If I were trying to EQ the battery I would raise voltage to 16V only after the battery spent a lot of time at 14.8v and amps tapered to a low level, about 1. If it took more than 5 amps to reach 16V I would give it more time at 14.8v before tryng again
So blasting right past 14.8v at high amperage is a FAIL.
Later on the schumacher trying to maintain my own AGM battery's prescribed float voltage of 13.6v failed, at one point when my compressor fridge shut of, voltage skyrocked past 15 and I pulled its plug. I knew of this behavior from when I used to use it in my rig, and it only made me appreciate the meanwell's rock steady chosen voltage even more.
I'd left meanwell attached to truck 27 battery until amps tapered to .98 at 10PM then removed it. Wattmeter claimed to have stuffed another 22Ah into it. 22Ah after the schumacher refused to do anything but float the battery.
Heard the truck fire up really quickly a few moments ago.
