Not really, low around 50's and high around 70s. I've also been driving more than usual. Unless there's a drain somewhere I'm not aware of.

not cold and not sitting. Since you swapped batteries guess you will see if it is a drain

It's a drain. The agm is struggling now. I'm having to charge it almost nightly. I believe it's coming from the behind the uconnect. After everything shuts down and if you listen real close, it sounds like a cd in a cd-player loading and it does this on and off while everything should be in sleep mode. I've checked most the other obvious stuff. Anyway, I'll update once I find out more.

That is normal shut down of vent system you are hearing, should be quiet after 10 minutes.

I'm really thinking its the uconnect or radio causing the draw. So the faint cd player/electrical sound coming from the screen continued longer than 10 min after shutdown. The only way I could get it to stop without disconnecting the battery was to pull the radio fuse. I updated to the latest uconnect, shut down, and then it only made the sound a split second and stopped (so far). Hopefully all is good now.

Not sure if this has been said. You need to store the ignition key away from the car. Otherwise the car keeps "waking up". Also this mey be intermittent making it hard to diagnose.

Fooling with the RC cars I learned you have to be careful with the LiON stuff. If they catch fire things get interesting real quick. I was spooked to try to jump start as I'd read reports of that frying the LiON batts.

I ended up getting the NOCO 5 charger. Amazingly it said if I ordered today I'd get it today and sure enough I did. It's charging the battery now although I think it's gonna take about 5 hours to get it full. Pretty happy with the little unit. Super compact and nice connectors, but I do wish it had the readout on it for voltage, temp, etc. 13,000 amazon reviews said it was great though.

Got this one: https://amzn.to/3WFIuBu
More amazed at same day delivery than the charger. You must be near the warehouse.

It was actually not the battery... Parasitic draw with the Uconnect. Fixed (so far) with the latest update.
