[QUOTE="FordTechOne, post: 1713326, member: 35543"] They are correlated, but charging system voltage does not reflect battery voltage. To check battery voltage you’d need to let the truck cold soak and then measure voltage across the terminals. 12.6V is a fully charged battery, 12.0V or less is significantly discharged. The most accurate way to determine battery state of charge is to use an analyzer, which most auto parts stores will do for free (here in the US at least). The analyzer measures the battery’s amperage capacity and compares it with voltage. Low voltage and low amperage means the battery needs to be charged, full voltage (12.6V) and low amperage indicates a worm out/failing battery. [/QUOTE]
