car battery with 14.5 volts
Started up the 62 t-bird let it run for about 10 mimutes shut it down and put the probes of my DVM and read about 17 volts while the engine was shut off. About a hour later the DVM reads 15.5 volts. Should I be concern or can some out there explain the happening. Larry Could I fix this my self. I also removed some of the distilled wated in the battery.
