Greater than one weekExcellent battery/cable ends. The quality of these cable ends is obvious. Worth every cent. They also crimp extremely well. Spend the extra few cents and get the WindyNation brand, you wont regret it.

> 3 dayThe WNI 1/0ga x 5/16 lugs are great...as long as youre NOT using Sky High Car Audio 1/0 wire. It wont fit without cutting strands. If youre using GP Car Audio, Knukonceptz or most any of the other brands of 1/0 car audio wire you should be good. The fit is snug on the wire. No issues using the hydraulic crimper.
