Store the car properly during winter
When the car’s battery is drained or dead, it is important to take steps to prevent this from happening again, especially during the winter months. Cold weather can further diminish the power of the car’s battery, leaving you stranded with a flat battery when you need to get out and go.
One of the best ways to ensure the longevity of your car’s battery during winter is to properly store your car. If you won’t be using your car for an extended period of time, such as during the cold winter months, it is advisable to take some precautions to keep your battery in good shape.
Clean and disconnect the battery
Start by cleaning the battery terminals and cables to remove any dirt or corrosion. This will help to maintain a good connection when you reconnect the battery later. After cleaning, disconnect the negative terminal first, followed by the positive terminal.
Store the battery separately
If possible, remove the battery from the car and store it in a cool, dry place. Extreme temperatures can adversely affect the battery’s performance, so it is important to store it in a location that is neither too hot nor too cold.
By following these steps, you can help to preserve the life of your car’s battery during winter and prevent it from becoming flat or dead. When you are ready to use your car again, reconnect the battery and ensure it is fully charged before setting out.
