Help with new battery

Texas_Edition · August 21, 2017

Anyone figure out for sure what group size it is for an XS Battery? My friend has a 2015 Z-71 and he's wanting to add a battery in the 2nd battery tray.

But I'm trying to convince him to just replace it with an XS battery.

I made sure to explain to him that you cannot mix a lead acid battery with an ATM battery.

I have no idea what an H7 or Group 94 (94R) battery translates to with XS. Their website & even their app, only goes up to 2012. They seriously need to update their Battery Application section. With 2018 models already out, that's 6 years now that it's out of date.

Wish my 2011 Titan Pro-4X had a 2nd battery trey. I bought me a large lead acid deep cycle battery from Atwoods (depending on where you live, you probably never heard of the place) on sale for $66 with a battery large box so I can mount it under the bed of my truck and then do "The Big 3 to help the stock, for now, alternator. I plan on upgrading to a Mechman G-Series 270a alternator exactly like the brand new Mechman G-Series 270a alternator I have sitting in the box, that was only test fitted, for my 2008 GMC Sierra SLT Crew Cab Texas Edition with an XS D3400. Had to sell the D3400, because I need a D3400R. Stupid reverse Polarity terminals. Never figured out a way to make my positive wires/harness longer.

So if anyone is interested in in a new new in the box Mechman G-Series 270a PCM alternator, let me know. Ran me $449, but I bought the $60 polished billet aluminum underdrive pulley for lighter unsprung weight, rust free, last forever & remain shiny forever too. So it ended up totalling over $500. Selling it for considerably less than that.

But anyway. Sorry. Wasn't planning on advertising my own stuff.

You can go to Batteries Plus website and find the correct XS battery. Thats where I got both of mine. I run a dual battery setup.If I can find my receipt I will post the number, its been a while and I dont remember off the top of my head.
