Correct answer
In parallel, with the same nominal voltage, correct polarity and the manufacturer’s specified points and procedure.
Connect in parallel with the same nominal voltage and correct polarity: positive to the designated positive point and the negative return to the earth or connection point specified by the manufacturer. Follow the manual’s sequence, points and precautions; direct connection to the discharged battery’s negative terminal is not universally required. Never reverse polarity or use a different-voltage source, such as 24 V for a 12 V system. A 24 V system must not be confused with an individual 12 V battery that may form part of it. Seek assistance if compatibility or battery condition is uncertain.
