There has been a lot of talk about how to charge the battery to extend the life. I'm not sure the battery can even be extended past 10 years of life since lithium-ion batteries are also prone to degradation just by time. But I'm wondering is it better to charge to the minimum highest state of charge that is required for the daily commute with some buffer of course? Or is it better to charge slightly more to avoid running the battery below 20% state of charge as it does not seem to like it there from what I heard? The commute is 40 miles one way and of course 40 miles back but this can be an extreme weather of almost -45°F. Nobody has any information on this or experience
