Testing charging car & mower batteries?

In the basement I have over 1 dozen car and mower batteries on the cement floor along a wall. I need to test them to see which ones are good, bad or chargeable. I have an automatic charger and an electronic voltage tester. Should I just test each one as they sit or charge first or? Some have been in storage for over 5 years. Where they sit on the floor is on one side of the landing of the stairs. On the opposite side of the stairs on this same basement floor are the water heaters which were new about 3-5 years ago. I'm concerned about vapors creeping over to the pilots on the water heaters. Maybe I could have a fan blowing on the batteries as they charge to dissapate the vapors?

I would not charge them near the pilot lites. Move them somewere to charge. And I would charge them first, then let them sit a bit, or put a little load on them to settle the voltedge, then test.

People will say not to leave a battery on cement. I dont know if thats true or not, just throwing that out there.
They say that storing them on cement is an old wives tale....But I still can't bring myself to do it.
LOL!! Yup. I hear ya. Well I go as far as LOOK for a board to put them on... if I cant find one, it goes on the floor. :D
