Quick Answer. A fully charged 12V lead-acid battery should read around 12.6V to 12.8V when at rest, while a reading below 12.0V often indicates a discharged battery. For a 24V system, double these values, and for a 6V battery, halve them. Understanding these voltages ensures proper battery maintenance and extends lifespan.
