Winter is just around the corner, bringing icy temperatures that can put a significant strain on your vehicle. The car battery, in particular, is sensitive to cold and can quickly lose power. But don’t worry, with our tips and tricks, you can effectively protect your car battery from freezing temperatures and start your day trouble-free.
Car battery being protected in winter
Ever gone to your car in the morning and nothing happened? The starter only turns sluggishly and the only sound is a pathetic clicking? Your car battery is probably weakened by the cold. But why is that? At low temperatures, the chemical reaction within the battery slows down, which significantly reduces the starting power.

Additionally, the engine needs more energy to start in the cold because the engine oil becomes thicker. This double effect can cause your battery to reach its limits faster in winter.
But how can you effectively protect your car battery in winter? First, you should ensure that your battery is in good condition. Have the battery voltage and charge state checked regularly at a workshop. A rule of thumb is that the battery voltage should be at least 12.4 volts when the engine is off.
In addition to regular checks, there are other measures you can take to protect your car battery from the cold:
Practical Tips for Protecting Your Car Battery in Winter
- Park your vehicle in the garage whenever possible. The temperature is usually higher here than outdoors, which spares the battery.
- Ensure good insulation for the battery. A special battery thermal cover or a simple blanket over the battery can already make a difference.
- Avoid short trips. On short drives, the battery doesn’t have enough time to fully recharge. Ideal trips are at least 15 minutes long.
- Turn off unnecessary consumers like seat heating, blower, or rear window defroster before starting the engine. This makes more starting power available to the battery.
- Check your battery terminals for corrosion. Corroded terminals can hinder current flow and reduce the battery’s starting power. Clean the terminals if necessary with a wire brush and some battery acid.

Besides these practical tips, you should also make sure to charge your car battery correctly. In winter, it can be useful to recharge the battery with an external charger, especially if you don’t use your vehicle for extended periods.
