For a bike battery you ideally want a charger around the 1 or 2 amp output mark.
A car charger will be higher than that i'd imagine (i don't drive?) so it'll be okay for an hour or two just to give it a quick boost. If it's a reasonably new charger it'll go on to a trickle charge anyway when it's sorted, if there isn't any light on it displaying a trickle charge then i wouldn't do more than two hours to be on the safe side. Saying that, if for instance it's a 10amp charger and a 5amp battery then no more than 30 minutes, you just need a bit of juice in it then the bike can do the rest!
Generally a charger should be 4 times less ampage than the battery it's charging, in an ideal world.
I deal with film equipment batteries and chargers daily at work, for my sins. :\
