I went in to Autozone with my battery to get it charged and tested. There were two guys at the parts counter, one about 35 yrs old and the other about 25. So the 25 yr old guy says, nope it's bad. It is only showing 6.5 volts. I said; then why is it bad. He said duh, that's way too low for a 12 volt battery. Astonished, I replied....IT IS A 6 VOLT BATTERY. He asked.....This is not for a car then, is it? Yes, I replied. He asked....what kind of car is it? 1955 Ford Fairlane, I replied. It went on and on, but long story short, neither of the parts counter guys knew that cars had 6 volt electrical systems in the past. The 25 yr old guy said...we don't sell 6 volt batteries here. I could see two 6 volt batteries on the battery shelf and I pointed them out to him. These two here ARE 6 volt batteries. I fear for the future of our country.
