Hello everyone, I’m trying to locate my auxiliary battery in the suggested places, I think it’s in the engine compartment but not positive if what I’m looking at is it. I took two pictures to post on here and if anyone can verify that it is the auxiliary battery I would appreciate it very much.

Please help identify this part and confirm if it’s the auxiliary battery.

No. If you have ESS ( eco start stop) it’s in the trunk next to the spare tire well. Dig down there

Rapid Oxidation is correct in your other thread, it's in the dash.
