You guys are just trying too hard.Â* I'll try to explain how I do it.Â* Once I figured it out its a piece of cake.Â*

Remove: Stick a few fingers under the strap in the middle of the battery, next pull up and towards the side that has the tapered clip, then once you have it stretched a little bit, with your other hand press down on the strap and pinch it on the battery.Â* Hold tension and slide your fingers to the clip and remove.Â* You should have slack now.Â*

Install: Pull (stretch) strap up and over battery with one hand and pinch it down on top of the battery again which should hold it in place while you slide the clip on.

If it is cold out be careful because it is easier to tear.. heat gun can help here.Â*

If you just fight the end with the clip it is a pain.. just pre stretch and hold for a good result..Â*
