Since I like to drive short distances, I think about whether I should recharge the battery on the charger from time to time. I am now unsure if I should disconnect the battery from the car, because I have read in forums of several people that they have the battery connected, but a well-known car specialist said that you should not do this because the control unit could then take damage. I really hate to take out the battery, because this is because The answer depends also on the type of charger and the charging voltage (which I could measure before with a charge in the developed state), or is it basically the same with all chargers? PS: Would it be possible to permanently attach a cable to the battery (in the trunk) with an adapter to which it is easier to connect the charger, or if it were not possible to connect the charger to the battery (in the trunk) or if it was not possible to connect the charger. Is this a safety-relevant part that should not be changed in this way?
