2nd Battery anyone?

[Nabbz]

Has anyone added a second battery to the 2015+ Yukon's? Looks like there is a dedicated spot for one but it's empty... and not wired of course.

Yep! It looks like it would hold a battery but it doesn't you need a new tray and battery holder. Then you just need wires and a 2nd battery.

Why not! It's cheap and you don't have to worry about your battery dying. The battery's also last way longer. The 2007 I traded in for my 2015 last December had the original battery and the 2nd battery I added a month after I bought it new.

If you use the Tahoe for any excursions 2nd battery is awesome. Running my fridge off it right now. Don't have to worry about starting battery dying.

This is a great idea. Anyone want to post a wire diagram?

On my 2008 the pos. went down to the pos. lug on the starter. Then the neg. over to the head.

just make sure the batterys are wired in parallel not in series and you add an isolator for like he said so the starting battery doesnt die

Does GM still make the wiring kit to add the 2nd battery?
