The short answer is yes, cold weather can absolutely affect and eventually kill a battery. 🧊🪫Cold temperatures slow down the chemical reaction inside, and your engine needs more cranking power to turn over, so the battery works harder when it's weakest. Here's what you can do: 1. Get your battery tested regularly, especially before cold weather hits. 2. Drive longer than 20 minutes in the cold. Startup drains a lot of charge, and short trips don't give your alternator time to put it back. 3. Make sure you have the correct battery for your vehicle. Size and cranking amps matter more than people think. You'd be surprised how many cars are running the wrong one!
