12.6 volts before I turn car on?
I Guess beer does make you dumb. Alright.. I'm learning how to keep a battery alive. 12.6 volts means that the battery is fiuly charged. 12.2 means I'm at 80%. before I start the car , lets say meter says 12.8, , once car is running the meter says 12.4, What is the rule for when I am driving around? When the car is running, what voltage do I stop running off the battery? SC
