The horrible feeling of turning the ignition in your car or van and having nothing happen has probably happened to everyone at least once, and in cold weather, this is even more likely to happen.
Why are batteries affected by cold weather
There is a reason why batteries are affected by cold weather and freezing temperatures. Most vehicle batteries use a liquid electrolyte solution to hold their charge, and this solution is affected by temperature changes.
Cold weather can negatively affect the electrolyte solution’s ability to transfer full power, and in extreme freezing conditions, batteries can even freeze completely.
