Does the 12V battery not charge when the truck is plugged into a L2 charger at home?? I'm asking because of the recommendation to put it on a 12V charger when you get it home. Would you have to disconnect the 12V prior to plugging it in or with the truck off it is safe to trickle charge the 12V
It does, but the maintenance is on a schedule instead of being reactive to the level of charge in the battery. There's probably some module that occasionally doesn't go to sleep when it's supposed to, or some issue with the DC-DC converter not turning on when it's supposed to. And all those trucks sitting in the lot, if they don't have their 12V batteries disconnected, they are going to run them down when not being used for months. Once a lead acid battery has had deep discharges, it doesn't work properly anymore.
