Thanks for this but you are not correct on a few things. You did not mention how to get from boarding gate to airplane. If it is a walkway from gate to plane door you cannot ride scooter on it. If it is a bus to plane plane then you cannot literally drive across tarmac to plane and and so require scooter to be placed on a bus ect. On arrival it would be the same to get from plane to departure. On some airlines they do not tell you to take batteries of but to just disconnect them on tmhen scooter.
