When a person didn't own a charger they would drop the car into the garage for a day and have them do it. On this occasion a Beetle was dropped in and I was given the job. I removed the battery caps(3 of as they were six volts) and connected the charger. Came back later that day to disconnect. I did this by leaning through the open window, leaning over the battery and proceeded to disconnect(probably with mains power still on) and BANG, it exploded in my face. Luckily with a large water flush there was no permanent facial or eye damage..
Technology can be amazing at times. I recently purchased a CTEK charger and I don't know how they do it, but it is safe to disconnect with mains connected as they produce no spark.
