When doing mine one at a time I place a rubber glove over the loose positive cable clamp just for ins. It's still hot from the other battery.

Good point.. Noted. But yeah, hopefully that goes without saying. I should've said it though.

I just replaced both of my batteries in my 2015 2 weeks ago. I replaced them one at a time so as to not loose any settings.
I used a bungee cord hooked to the hood to hold up the positive cable. The bungee was approx 15" long and held the positive cable up and out of the way on both sides. Took about 5-6 minutes per side to replace them which included cleaning the cable terminals.

Larry, did you use anything to keep the cables free from acid build up? How did you know they needed to be replaced? My '13 has the original batteries in it. What batteries did you go with? Sorry for all the questions. I'm starting to get a bit nervous about my truck still having original batteries in it. Driving to Florida from Connecticut and back in September, the last thing I want to do is get stranded by something as easy to replace as a battery.

I would pro-actively change those 6 year old battery out. 95 bucks each at Costco. Cheap ins. I use NOCO corrosion preventive spray sold at Napa My old 05 truck at 10 years old still had the original cables in excellent condition.

My 2013 has the orginal batteries too. I am not bothering with changing them until I see signs of needing a change.

These 6.7's seem pretty forgiving when it comes to batteries, my 2014 spent months at a time sitting and I just recently had to change them, if it was below 20 degrees and it sat for more than 2 days it wouldn't start. The only reason they went bad though was because I accidentally drained them (wifi-router for some LED's in the headlights) and it got well below zero and truck was in a storage unit for over a month without being started. It killed the batteries and they never were the same after that. Replaced them with X2 powers by Northstar, roughly $550 for the set, but man it starts like a champ every time now.

I did use the spray battery acid neutralizer on each side prior to installing the battery. I did clean and repaint the hold down bars. I put the red/green rings under each terminal. Some of the rings are now gray in color for both. I sprayed the area good with WD-40.

Fluid film works good on battery connections.
I have even better luck with a product called WHIP. I use it on all of my lawn mower batteries. Warning do not get this stuff on you its like tar but only thinner and will not come off easily. I've ruined a few shirts with this stuff.
Whip Carosion Remover
Your local auto parts store should have it.

I ordered a can of Whip from the website posted above on the 15th. Haven't received it yet. Sent the folks a message this morning to see where it is / if it has shipped yet. Way too used to getting stuff from Amazon in 2 days. Odd that I haven't received at least shipping notification.
