Sounds like you only drive it once in a blue moon. When you're ready to drive it more, buy a new 6 volter with the right dimensions from tractor supply, install it and forget it except maybe for removing the ground terminal. You don't need a switch or solar power. Just take the battery home with you and keep it on a tender if you expect the car to set till the next blue moon. Jack E/NJ
