How to charge a car battery correctly is a question we are often asked unfortunately this is often when attending an assistance call where battery problems have led to a breakdown. My old charger I used to use in situ. Personally I would only do this for trickle charging 2 amps otherwise I think the general advice is to disconnect.
To charge you simply plug the cable end into the corresponding cable on the charger and switch it on.
Then disconnect the red cable which is connected to the positive terminal. Always disconnect the negative usually black lead first and reconnect it last otherwise you could end up getting a nasty shock when you touch the positive terminal. As soon as additional charging becomes necessary whatever age the battery then its not long before a new battery is needed assuming the car is in regular use. My old charger I used to use in situ.
