Disconnect battery when parked?

A simple disconnect is a cam-loc welding cable disconnect on the battery negative ground wire. Used it in my 69 Charger for years and years. Simple quick twist and your safely unplugged. Simple quick twist and your plugged back in.

Moroso makes a really slick one, it a battery terminal, with a knob on the top, just rotate the knob, no power.
