Truck Year/Model/Engine: 2016 Freightliner Cascadia Detroit DD15
The batteries on my Freightliner Cascadia kept going low and I didn’t know why. I have had already had to get jump started a few times by some noble truck drivers! Shout out to those guys! So I knew I had to go to a dealership or a place that sells CMV batteries to get them replaced. Check out how fast and easy I swapped one of them in this video!
