Oh, and glass,wood and hard rubber are VERY good insulators of electric current. How in the world could you expect 12 volts to be able to cause current to flow thru several inches of air (or glass) and then wood, and then into the concrete?

Now maybe if the wooden cased ones were so tight as to swell then they got wet from the moist concrete would cause them to break, but it is not going to cause discharge from just sitting. I mean glass has an insulating value of thousands of volts per inch.

Those glass cases were inside wooden boxes when used in cars or as storage batteries for homes and they did discharge from sitting on damp surfaces. The primary offenders were the early hard rubber/plastic cases which were porous and held enough moisture to conduct.

With correct fluid levels, fully charged, it needs a load test. Then, you will have your answer.
As for where I sit my batteries, I never sit mine down on bare ground or concrete - mainly because I don't want to be confronted with "DON'T YOU KNOW YOU AINT NEVER SUPPOSED TO...".
I remember back in school they said "A man convinced against His will, is of the same opinion still". In other words, when you "Straighten them out" they might go "Oh, OK", but in reality they are probably thinking "What a fool, everybody knows better than that".

Hello: A multi meter is worthless to test a battery. Get a new battery tester that will tell you how much battery life is left and voltage and test starting system . I think the tester I bought was around $50.00. It is a Konnwei kw 600. My buddy had trouble with his car starting reliably. Would not start every time. He told me he checked it with his multi meter and it always read over 12 volts. I told him it was his battery and bring your car over and I would test it for him. Tested it with my electronic tester and it read replace. Good Luck. O - R

Sounds like a current draw to me & not necessarily a bad battery.

The very antique batteries in the pics would discharge but the modern deep cycle trolling motor batteries like Catfan's talking about & the original poster is asking about definitely are not discharging because of being sat on concrete.
