Can I charge the battery with it still in the car?

Or do I have to disconnect it first?
Haynes manual says you have to remove it to charge?
Just noticed that as I was looking through it...

I think you would be perfectly fine to leave it hooked up. I have never had a problem. Just make sure if the charger does multiple volts that its on the 12V setting.
