I left my key turned in the ignition for several hours yesterday, so I wanted to charge up the battery a little, but when I examined the battery a bit closer I noticed that it's probably not a maintenance free battery that I thought it was - see the cap in the photo that I have removed... Last time I saw a battery like that was back in Europe 25 years ago where I used to live.

So the question is: should I remove the battery out of the car and place it in a dry spot outside, then pop all the caps off and THEN hook it up to the charger? I remember way back when my dad was recharging a battery like that the acid in it was boiling pretty vigorously...

Thanks in advance -
James
