From time to time I would like to trickle-charge the A3 battery. Is it OK to do this by just simply connecting the mains charger (+ to + of course)? I have heard several opinions on this, and some people say that one must remove the battery from the car, or risk damaging the alternator (or something else). What would be the advice of members please? Thanks in advance.
