When charging a dead battery in a car -- do I need to disconnect the positive and negative terminals and then connect the charging clamps to the battery? I have been doing that so there would be no chance of harming the cars computer -- but maybe that's not necessary? Also, on a car with a computer, would any harm be done to the computer if connecting the charger to it and then using the "start" function selection which would put a much larger charge into the battery for a shorter period of just the starting time? What general precautions are there when jumping or charging a battery so as to not damage the car's computer? Thanks Gene
