I hear everyone saying 'Don't connect a charger with battery disconnected' - but no-one seems to know WHY you can't do that....?

Because the battery itself pulls the charger voltage down to something reasonable, many older chargers supply 15-17 volts unloaded, they are also often only half wave rectified - again not something the car's electronics would "notice" when a battery is connected supplying voltage during the "dead" inverted phase. In essence, the power supplied by many battery chargers is far too dirty for modern cars, the battery acts as a damper cleaning the power supply up.

Yeah it's to set the anti trap. Personally with the drivers window in particular, i would prefer, if anyone tried to reach in to do harm, to be able cut their bloody hands off at the wrists.:D:D:D
