1976 club car, the batteries are about five years old. It is only used about four months a year. When put in storage the water level is brought up, they are left fully charged. When taken out of storage they water level is checked and recharged. This fall it didn't have the speed of last spring. Today it would not move forward, but would go back. After moving the forward reverse lever back and forth it would move forward, but not with great speed.
