2020 Silverado Crew Cab Custom Add 2nd Battery

Recommended Posts

I need to add a second battery to my 2020 Silverado CC. In previous years, it was simple. There was even a place. I don't see a single option or place to fit one. I called my local dealer multiple times to ask, but they never call back. Anyone else figured out a way to do this? Where is a good spot?

Yes when they moved the battery to the firewall on the left with the previous gen trucks there was the old spot on the front right for one. Now with the redesign they have removed that space. Supposedly the 2500 diesels still have the 2nd battery. Maybe trade up? LOL

Yeah my 2015 had the extra hole, and even instructions in the book. Having a extra battery is a "gotta have" for lots of folks. That was pretty stoopid.  Especially the way these over board  sensors  nanny noses eat batteries!
