great posts. I see that you live in a very cold climate with ice. Do you park your car in the garage or let it sit outside where moisture and condensation could accelerate the corrosion of the terminals?

 

most of time is inside garage but when you go somwhere its park outside .regardless of the weather oxidation on the terminals will be happening all the time.Now new approch we testing is to middle cells put outside and outside we put in the middle .on that way battery got longer life and less corrosion because overheting is less happpening .temperature is more present in the middle and those cells will be giving up but if you rotate them regullary than those cell will last longer .i think once a year rotation will be great and they will balance itself.
this was one more idea for educational purposes only.
