MightyMax 18Ah AGM battery

[TWIH]

SW, I did hook up the 10/2 charger, set it to the 2 amp side and left it on for 12 hours.  Case of the jump pack was still cold to the touch and the meter on the charger was all the way over, so perhaps that 14.4 to 14.6 it can put out helped some. I just charged it clamp to clamp with the switch “on”, thats about the only way I have to override the internal ac charger its built with.  I have no idea of the electronics in the “smart” charger and when it goes to float, but it was worth a try.

Thanks for the reminder to try and elevate the voltage.
