Some people suggested to take both positive and the negative terminal off the battery. Is this not necessary?

Thanks for watching and commenting, no you don’t have to take both of, the most secure is to take off only the negative side, however the computer wouldn’t know the difference. If you take off both you are definitely sure no creeping current is left in the system. Hope that helps Drive safely best regards Rene
