I had a powerstroke . I put everstart in they failled. I put two optima yellow top they failed . $400 dollars waisted . thought something was wrong with chargin system changed altenator . glo plug relay thinkin it might be that draining them wasnt those things either. Finally went with interstate workaholic cured all ills made the battery gauge go even higher than when the truck was new and I sold the truck a year ago and they are still good after six years . When I purchased my first cummins used batteries went out bought insterstate they are doing great too.I also have 2 Red Top's https://mechanicguides.com/best-batteries-for-diesel-trucks/ in my truck they are 2 years old. We get very cold weather here I have never had a problem with them. In fact, my wait to start light has always been faster and it cranks faster than the original batteries. I gave a 9 year old red top to my friend with a old Cougar, its still works like new. One of the biggest problems people have with batteries is they don't replace both at the same time. You need matching batteries otherwise one will be pulling more current all the time. I have heard of the people having issues with red tops but it is a misconception, most of those problems were related to poor cables and or grounds. You need at least a 650 cca at low temps, most batteries are rated around 40 degrees.On YouTube there are a lot of interesting videos on this topic,check out this, I hope its help you.Good Luck
