Yes, you can charge from the jump posts under the hood. Or easiest and best is the hook a female dongle end to the battery and then just connect the male section whenever you want to charge it up. Unless you do lots of hwy driving, it is always good precaution to plug it into a tender/charger every few weeks or so. This will maintain a very healthy and strong battery for many years.

 

happy to have found this. In this last few weeks I've received two emails from "the truck" alerting me that the battery is low and I need to go drive it.
On my car, I've been able to hardwire a pigtail that allows me to plug in a CTEK trickle charger as needed, and I'd love to do the same with this '22 D5.
but not clear where the optimal place to do that on it would be. In my car I was able to do it in the truck by some power modules
with ring spades. Not sure if this is an option here.
