What is a normal battery voltage for a 2004 Honda Pilot?

Oh honey, we're talking about a 2004 Honda Pilot, not a vintage wine. The normal battery voltage for that old gal should be around 12.6 to 12.8 volts when the engine is off. Once you start her up, you're looking for a range of 13.7 to 14.7 volts to keep her purring like a kitten.
