Correct answer
A voltage of 24 V.
24 V: the nominal voltages add in this series connection, 12 V + 12 V. The result is neither 12 V nor 18 V. Actual measured voltage may differ from the nominal value with charge state and conditions. This result does not authorise connecting the combination to a 12 V system: follow the vehicle’s design and manufacturer’s instructions.
