<strong> You can charge the battery as much as you like without removing any connectors. The average home charger can not compete with the alternator. Some chargers however are so powerfull they create an elctronic disturbance, fooking up the electronics, so starting the car with these units connected can hinder correct operation of the ECU, and set the airbag warning light.

I have a heavy duty start charger and have had to use it a couple of times on the Selespeed (if ignition is left on it seems to run the battery down really quick, I guess the selespeed pupmp takes power).
Anyway this has a 200Amp boost function, I've always connected it at a basic trickle charge to the battery then turned starter motor and only then kicked in the boost. Its done the trick for me every time.
Maybe I've just been lucky.
