Just realized my grandpa was right about putting a battery tender on the Buick every winter
I used to think pulling the battery out of my 1965 Skylark and sticking it on a shelf in the garage was good enough for winter storage. For three years I did it that way, and every spring I would drag it back out and wonder why it cranked slow or needed a jump from my truck. Then my grandpa, who kept a 1955 Chevy running for 40 years, told me to just leave the battery in the car and clip a tender on it instead. I finally tried it this past November on his advice, and when I turned the key in April the thing fired up like I had parked it the day before. Same battery, same car, same cold garage in Ohio, nothing changed except that little float charger. I think what sold me was checking the voltage with a meter: 12.6 sitting there all winter instead of the 11.8 I used to get after a few months on the shelf. Now I am thinking about whether I should be doing the same thing for the riding mower and my wife's car that sits a lot. Has anyone run into a tender that boiled a battery dry, or do the good ones really shut off on their own?
