I'm in northeastern Ontario (usually see roughly -35 degC to 35 degC in a year).

I've been super impressed by the battery in my car. 7 years old and left to die from lack of use (second car plus pandemic). I've boosted it back to life probably half a dozen times now, and it keeps going.

We've all got bets going about when it leaves me stranded. There's no way it's very healthy, and there's no way my alternator hasn't been close to catching fire at some point.

But if I replace them now I'm going to be in the same position before long. Hardly seems like the time.
