Never seen this before. Interesting concept. Sort of like quick hubs or seat release on bicycles. Might work on marine batteries where they are on/off often. Then again, marine batteries generally have two posts for such reason. Maybe in a car with slow drain? But, I think I'd rather find the drain and fix it. Maybe for swapping batteries between multiple vehicles? Say you have a stable full of classic cars and one battery for half a dozen vehicles. I guess you could disconnect and leave in the vehicle for trickle charge over the winter as well but I usually don't disconnect for this. Help me figure out "why" you would need these. I mean, they are a cool idea. Just not sure the application or necessity.
