1. The cold weather can thicken the oil in your engine, making it harder for the starter to turn the engine over. This can put a strain on the battery, especially if it is old or weak.
2. The cold weather can also reduce the battery's capacity to hold a charge. This is because the chemical reactions that take place inside a battery are slowed down by cold temperatures.
3. If your car is not driven very often, the battery will not have a chance to recharge fully. This can lead to the battery becoming discharged, especially in cold weather.
If you are having trouble starting your car in cold weather, there are a few things you can do:
1. Try to park your car in a warm place, such as a garage or covered parking.
2. If you cannot park your car in a warm place, try to start it for a few minutes every day to keep the battery charged.
3. You can also try using a battery booster to jump-start your car.
If you continue to have trouble starting your car in cold weather, you should have the battery tested to make sure that it is still good.
