Dealing with cold weather battery problems

When the temperature drops, car problems inevitably rise. In larger terms, this is unavoidable, but there are things that you can do to minimise the chances of your being stuck, unable to start your car.

First of all, why does the cold affect your car so much? The main reason is that lower temperatures have an impact on the chemical process that allows a battery to store and produce electricity. The process is slowed, resulting in reduced charge and if your battery is already ageing and weakened, this might tip the balance so that you can’t start your car.

There are a few things you can do to look after your battery better in cold weather. The first, and most obvious, is to use fewer things that draw on that power. Obviously, you can’t drive without lights or windscreen wipers, but your heater may rely on battery power, as will your in-car stereo. It is also a good idea to switch these things off before you turn off the engine. This results in a lighter load when you come to start the car again.

It might also be worth checking your car’s spark plugs. It may be that they need replacing, in which case you can purchase new ones at a site like but it could also be that they just need cleaning. It is certainly something worth looking into before diagnosing a battery problem.

If your battery is flat, you will need to jump start your car, but there is much you can do to prevent a problem in the first place. When the weather turns cold, be aware that there are two issues conspiring against you. One, your battery will have reduced power due to slower chemical processes in the cold and two, you are likely to be making greater demands on it when driving through using various heaters.
