These guys are awesome! Read the data online, you can’t beat interstate. I have an F250 Diesel that takes two big MegaTron batteries. Last ones made it 5 years and they prorated me a deal toward the purchase of two new ones. I go up north in the winter and need heavy cranking power in below zero winter temps. Really friendly, fast and easy to work with. I pulled the truck up and they had both batteries swapped out in no time. Worth the drive out of town. Will definitely be buying all my batteries here.
