"jump packs" don't charge anything - not in a battery-friendly way anyhow.I had my truck at the dealership for some work about 3-weeks ago. It sat there for about 5-days and when I got it back the secondary battery was too low for ESS to work.
Thing is, with ongoing COVID stuff (I just don’t drive much) and the fact I have a parking mode hardwired dashcam always running, that secondary battery has only once had enough charging time to re-enable the ESS system—and even then, just for a short time before sitting and draining again.
Prior to the dealership visit, the truck could sit equally as unused and still always have the ESS battery work just fine.
I just wish I had a better way to charge the batteries than driving around for hours (I have a 1500amp jump pack, but that seems to be insufficient to fully charge the batteries).
Get a battery tender (battery minder, whatever the trade name is) you can plug in when close to an outlet and not driving it.
Mine has a connector so I can leave the cord connected to the battery and dangling behind the grill and simply plug the battery tender to it and not even open the hood. I use one for my classics that sit a lot.
My wife's GC sits sometimes for a week or two at a time, now my JT will be sitting as I have no place to go and the way Iowa is going, I'd rather not go out and about with sick people at every turn.
