Brought home a new International 28 friday night and left it in driveway disconnected from shore power but with battery switch in "Use" position (clicked up last). Lights, furnace, fridge and everything were turned off.
In morning, battery was so dead that interior lights would not come on. Surprised me actually. Guessed that dealer must have given it to me with very little charge on battery. Not sure what would have discharged it over night. But regardless, saturday morning I plugged into shore power.
Tonight, Sunday (so 35 hours later) I went to check state of charge. Battery V indicates 13.4V (but while on shore power). But when I unplug it it says only 12.2V. Batteries should have more charge than that. There has been nothing on to consume any power.
So how long should it take to charge batteries to 100%? Over one night should be plenty. Feels like something is wrong.
