Hey there, fellow drivers and winter warriors! Ever wondered why your car seems to groan and protest on those chilly winter mornings, almost as if it's begging for five more minutes under the blankets? Well, it turns out, cold weather does have a significant impact on your car's battery, and here's the lowdown on why this happens and what you can do to keep your ride reliable, no matter how low the mercury dips.


Does Cold Weather Affect Your Lead Acid Batteries?

Absolutely, it does. Lead acid batteries, the traditional powerhouse behind most vehicles, are quite sensitive to the cold. In freezing temperatures, the chemical reaction that generates electricity in these batteries slows down, reducing their capacity to hold a charge. This means that if your car battery dies in cold weather, it might struggle to recharge, especially if it's already nearing the end of its lifespan. Moreover, the increased electrical resistance during cold starts means your engine requires more current than usual, putting additional strain on your battery.


Does Cold Weather Affect Your Lithium Batteries?

Lithium batteries are not immune to winter's chill, either. While they handle cold weather better than their lead acid counterparts, their performance can still take a hit as temperatures drop. The electrolyte solution inside lithium batteries becomes more viscous in cold conditions, hindering the flow of ions and, consequently, the battery's ability to deliver power. However, the effect is somewhat less dramatic than in lead acid batteries, and they recover quickly once warmed up.


What Can I Do to Keep This From Happening?

Fear not, for there are several steps you can take to shield your trusty steed's battery from the cold:

  • Keep it Charged: A fully charged battery has a better chance of fighting off the cold. Consider using a battery charger or maintainer, especially if you park outdoors.
  • Park Smart: Whenever possible, park your car in a garage or another warmer area to protect it from the worst of the cold.
  • Battery Blankets: Yes, they exist! Battery blankets can keep your battery warm, improving its performance in cold weather.
  • Regular Checks: Keep an eye on your battery's health. Regular testing can alert you to potential problems before they leave you stranded.
  • Turn off the headlights: Keeping the headlights on will generate additional power consumption from the battery, leading to faster battery consumption. So we suggest turning off the headlights if possible.
