This is a basic plastic strap that works by putting the metal ends over the terminals (no way to 'short' the battery through the plastic) and when the heavy battery is picked up by the terminals the metal is wedged to them. Mine is red and this shows black; Color does not matter. Make sure the metal ends are all of the way seated or it can drop, make sure that the terminals are secure, and maybe have a hand under it in case the terminals come loose from the battery. The dropping of the battery could easily break a foot bone, the battery, and/or spill the contents of hydrochloric acid or splash it. It still requires some strength to pick up and some time and skill to position it, but it works well when used right. I would probably have gotten the metal type with a handle if I did this a lot, but all of my other batteries, except one, come with a built-in strap. Trust all straps like a grocery bag.This was for an OEM, AGM, heavy (more lead), replacement for a defective battery within the warranty period. I recommend this, would buy again, and I hope this helps.
