It depends if your charger is likely to sent voltage spikes through the system, I have an Optimate (getting quite old now actually) that I have no problem sticking straight on the battery but I don't think I'd trust the cheapy I got from Lidl on there.

I follow this procedure viewtopic.php?f=10&t=13431

before disconnecting the quick-release clamp on the battery positive terminal, then connect your charger to the battery.
(I always do it this way on the 807 as it's a major ball-ache removing and refitting the battery).

It's perfectly safe to charge the battery with it still connected to the car as long as you follow some simple rules....

Be sure there is plenty of ventilation around the battery/car.
Don't switch the charger on until all connections are good.
Switch the charger off after charging and before taking the leads off the battery terminals.
Take care there are no possible sparks anywhere near the battery whilst it is charging.
