you'd think there was some kind of ISO or UNECE standard about not letting a car die in the middle of the road by design.

you never know
even BMW has a specific procedure to change their battery

and never ever trust the shop staff too, their knowledge is worse than the owner or normal people
i order a battery change for my saga and that dude also didn't know the correct procedure to change it

he really thought he can just unplug whichever terminal is easier and put it back on whichever way/order he wants
