2019 JLU 2.0t, mild hybrid.

No idea why but when it sits for more than a couple of days (and I am on the road 10-15 days a month), both batteries are dead.

Jump starting doesn't work the normal way, but another JL forum had a thread about using the N5 post to charge the ESS battery which is actually what starts it.

1. who is the genius that designs a "mild hybrid" with two batteries, and leaves so much equipment running when the vehicle sits that it kills both batteries. Definitely not a vehicle to go out in the back country with!

2. HEY JEEP! PUT THAT $41T is the owners manual. The manual describes in painful detail how we all learned to jump start our first cars when we were 15 trying to get a license. No mention of the ESS being the battery that starts it or the N5 post. Jumpstarting did not work, my battery booster did not work so here I sit with a trickle charger on the battery currently reading 3.5 Volts.

3. Could someone please post a picture of where this mystery N5 post is?

This is Painful, especially after the JK issues.

Thank you
Brain aka CoolToys guy.

OK took off the fuse box cover under the hood, and found the N5 Post that many reference in other forums for faster jump starting.

I wonder if you could hook up two trickle chargers? One to main battery, one to N5 to speed up the recovery process. This really is stupid.
