Silverado 1500 Crew Cab - Dual Battery Options

[JButtress]

Hey, does anyone have any tips on what battery to go with for my dual battery set up? I already have a 2nd tray under the hood ready to go. The area is about 12" x 8" and roughly 7 1/4" tall and i'm having a hard time finding a battery that will fit. Has anyone already added a dual battery to their Silverado? Thanks

I hooked up a red top Optima. Here is a video series I made and links to the parts I used.

I went with a Yellow Top (Part No. D34-78) and a battery isolator kit for my 02 2500hd.

Based on this quick search it's the right height that you posted - Optima Batteries YELLOWTOP Battery Group D34/78 750 CCA Side/Top Post - 8014-045

When I switch it up to a dual battery setup I will go with Optima Yellow tops

I ended up deciding against it, and running a northstar AGM as primary, until I find ill need 2nd battery. I'm eyeballing the 2nd tray for a location for my viaair compressor though!

When my primary Optima Red is done, I'll probably switch out to the Northstart as well. Seems like a lot of people in OB recommends it as well as the positive reviews I've briefly read...

What year is your Silverado? I have two group 48 AGM batteries in my 2011 Tahoe.

Ah the gmt 2k or some such chassis. I’m sure someone else here has already run that trap.

Umm, yeah me. lol
I had the extra red top Optima because it was in my last Silverado and I kept it. I figured why not add it to this one for additional power for my emergency lights. I don't use emergency lights anymore so I will be using it for my camper or possibly s backup start battery.

Thanks for your video above as well. I think I ordered a few things off your list that I didn't have
