About 3 weeks ago my work truck (a F#%d) wouldn't start. The battery was dead, so I took the battery out of my 53 to get it started. Since my 53 is on jack stands while I'm working on the steering, I set the battery on the garage floor.
Today I decided to start my 53 for a cruise around the block. I put the battery back in it and it was dead. I tried charging it and it won't hold a charge.
Did leaving it on the garage floor for only 3 weeks kill it?
I always thought that was an old wives tale about not setting a battery on a concrete floor. The battery is only 1 year old. Any thought's on this?
