I was kind of curious when do you guys replace your battery do you wait for it to absolutely fail and leave you somewhere or do you do it preemptively? The battery in my focus I'm pretty sure is original from 2017 there's no markings on it if a manufacturer which makes me think it's a factory battery. It's state of health is 45% 397 cold cranking amps out of a rated 590. Would you replace it or would you leave it be?
