If you own a 2007-newer Tahoe/Suburban/Escalade and your lights are flickering and your radio won’t hold the time? Chances are your battery cables are shot. Can’t tell by looking at them. My new (3 month old) battery drained down for no reason. Found out the ground was bad where it connects to the frame. So went ahead and replaced both the ground and positive cables with these brand new factory replacements. Haven’t had a problem since. These cables are a life saver!
