Had similar issue with new 6v. Optima that wouldn't hold charge. Now with maintainer on it , it's fine. We install good battery cut of switches (Cole Hersey, etc.) in all cars in the interior for convenience as in the Andrews green book for both 6 and 12 volt and shut off the switches after every use.
