|Select this option if the car has any of the following: The stock battery has been replaced with a smaller battery. Any of the batteries have been removed completely. The car has any lightweight battery, including any factory-installed optional lightweight battery if it was not standard equipment for the car's series, type and model.|
NOTE: Typical examples are the 1973 and earlier 911s that were equipped with 2 batteries. Removing one battery would require this option to be checked.
NOTE: An exception is the mid 70â€™s 911s which had a single huge battery. It is acceptable to replace this with the smaller of the original batteries that was used during the same period with non-air-conditioned cars.
