Recommended Charger for 2018 Jeep Wrangler JLU With Main and Aux Battery

Question:

I have a 2018 Wrangler JLU Rubicon V6 with a Tow package which comes with a larger 12V 700 CCA AGM Main battery and a smaller 12V Auxiliary battery. I currently have a NOCO G3500 which I am attempting to charge the two batteries in parallel and is taking a very long time. Will this unit work better? Would the force and repair feature of this unit be okay to use with these two batteries in parallel?

The NOCO Genius Smart Battery Charger - AC to DC - 6V/12V - 10 Amp # 329-GENIUS10 is a great option for charging your batteries. The way your batteries are connected would be good to know. If they are in true parallel this will work well. If there is a solenoid involved, then your second battery won't receive power unless the ignition is on, so if that is the case you would need to have a second bank connection for a multiple battery charger like # NOC94FR or a complete separate charger.
