For anyone interested or trying to troubleshoot battery drain problems, I measured the battery power drain on my (healthy) JLUR 392 with the vehicle parked/off. The drain was 0.090 Amps (a pretty typical modern vehicle drain value).
This means the battery gets drained at about 2.2 Amp-hours per day / 15.4 Amp-hours per week / ~66 Amp-hours per month.
For reference, the standard H6 battery (when new) has a capacity of about 70 Amp-hours. The capacity decreases with age.
Sometimes a bunch of days go by without firing up the Jeep and I'd wondered how much the battery is getting run down. It always starts instantly, but knowing that partially discharged batteries tend to fail early means I didn't want to let it go too long either.
Confirming what many on the forum have pointed out, it looks like I should up my game and get a battery maintainer connected when the vehicle is going to sit for more than a few days.
