Fun fact Friday!
Have you ever wondered why car batteries often seem to die as soon as cold weather hits? There's a lot of chemistry to it, but in simplest terms it's because like everything else, even electrochemicals don't like to move in colder temperatures. Internal resistance is increased in cold temps, which essentially means the chemicals inside the battery have to work even harder just to provide power to the starter.
And this process often begins in the summer months. Extreme heat can cause an accelerated breakdown of a battery's internals, weakening its lifespan. Take a battery that's been beat up by years of hot summers, combine that with a cold snap, and bam; you turn the key and *click click click click click!*
Most batteries seem to have an average lifespan of about five years. If your battery is over three years old, we recommend getting it tested and replaced (if needed) BEFORE you're stuck in your driveway on a cold winter day, late for work while waiting for a jump. 🥶
