Trevor said "The only suggestion I’d make that hasn’t been mentioned yet is to consider if a battery is made from new or recycled materials. My experience is that the ones made from recycled materials don’t last nearly as long.
I’ve got one in my truck currently, and it’s only 2 years old. Once the cold temps hit it failed. I took it out of the truck, fully charged it, and put it back in. Next day it failed again, so I took it to the retailer. They tested it, said it’s fine. I gave them the benefit of the doubt and put it back in my truck again yesterday. 5 hours later it wouldn’t start. Last recycled battery I ever buy. And I feel like I won’t get warranty either, despite it having another 10 months of free replacement. "
If it were me I'd suggest they put tit in there own vehicle and see how well it works.
