Vehicle: 2015 Legacy 2.5i, 33k miles (new to me as of a month or so ago)
Battery: Group 25 (pretty small, compared to the size of the tray)
-----Previous owner says it's stock and that she doesn't recall it ever dying
Battery Died: car was being worked on - had to be jumped when I picked it up 3 hrs later
-----Immediately drove home 25 minutes and pulled the battery for charging
Charger: Solar Pro-Logix PL2520 - Will charge at full amperage, then go into desulphate mode (~13.3VDC) then turns off
-----Read 12.8VDC when I hooked it up and 90% charged (yeah, right; surface charge)
-----Still charging at 14.5+VDC on 10A setting 3.5 hrs later, when I went to bed
-----Fully charged (charger turned off) and indicating 13.0VDC when I woke up the next morning
-----Between then and now I've tricked the charger into continuing by turning it off and then restarting it 3 times --> each time, the charger would indicate full within 10 minutes and switch to desulphation mode, which it would operate on for hours (I did not measure the exact time.)
Specific Gravity: while still on the charger @ 13.2VDC I checked the specific gravity with my cheapo hydrometer and found the following:
1. 1.237 (the hydrometer has a big gap between 1.225 and 1.250, so, by eyeball it was nearly halfway between the two)
2-5. ~ 1.265
6. 1.237 (by eyeball, it was closer to 1.250 than 1.225, but still in the unmarked space)
I also load-tested it:
