Why Car Batteries Die in Cold Weather, and How to Prevent It

When winter comes and it gets freezing, many people have car problems. This happens a lot, especially in winter. Why does it happen, and what can you do about it? This blog will discuss why car batteries die in the cold and how to ensure your car runs well in the winter.


           Why Do Car Batteries Die in Cold Weather?

To understand why car batteries die in cold weather, let’s look at how they function. Batteries convert chemical energy into electrical energy, providing the power to start your car. However, when temperatures drop, this process slows down significantly. In fact, once the mercury dips below freezing, your car battery loses about 35% of its power, making it less efficient at starting your vehicle. Adding to the challenge, the cold also causes engine oil to thicken, increasing resistance and requiring even more power from the battery to get the engine started.

How To Prevent Car Batteries from Dying in Cold Weather

  1. Get a Battery Checkup: Before winter starts, have a professional inspect your battery with a Renault repair specialist. This checkup can reveal its current condition, lifespan, and whether it can handle cold temperatures.

  2. Keep Your Battery Warm: Car batteries prefer warmer temperatures. Parking your car in a garage or covered area shields it from the biting cold, helping to maintain optimal battery performance.

  3. Turn Off Electrical Accessories: When starting your car in cold weather, minimise the strain on your battery by turning off electrical accessories such as the radio, air conditioning, and headlights. This reduces the load on the battery and improves its chances of successfully starting the engine.

  4. Drive Your Car Regularly: Long periods of inactivity can cause your battery to lose power. Regularly driving your car keeps the battery charged and prevents it from succumbing to the cold.

  5. Invest in a Battery Heater: Consider installing a battery heater to keep your battery warm and cozy, even on the coldest days. This device attaches directly to your battery and helps it maintain optimal operating temperature, ensuring reliable performance when you need it most.
