Charging battery while in the jeep

[Jeepfueledbydiesel]

I searched but didn't find what I was looking for. I have a CTECK 7002 and I have hooked it up to my other vehicles to charge the battery at times to keep them topped since we do a lot of short trips.

Can I hook it up to my 2022 Wrangler with the Ecodiesel and will it charge both batteries? Thanks

Yes. The CR[an]K and AUX (ESS) batteries are connected in parallel when the JL ignition is in the "OFF" position, so if you're charging one battery, you're charging both.

Be sure the Intelligent Battery Sensor (IBS) is between the charger's negative terminal ring/clamp and the negative battery post - that is, "blind charging" the JL CR[an]K battery is not recommended.
