This is a ducky solution. There is less chance that your battery will leak acid and corrode anything. The battery sits up high where it should be, but has a sort of wooden diaper to prevent it from misbehaving.

It's as elegant as a solution could be.

Battery quick release gizmos have a plastic knob (mine has a green knob) and you can disconnect the battery without a tool.

There is another type that has a knife switch.

Remember that your MBZ radio will not work if you disconnect the battery unless you punch in the code. I am sure you are aware of this.
