A dead battery is a common culprit when cars fail to start in severe frosts. A Novosibirsk auto expert named Ruslan explained this to Sib.fm, noting that cold conditions dramatically reduce a battery’s ability to deliver the surge of current needed to start an engine.
To address the issue, Ruslan recommends temporarily borrowing power from another vehicle with a similar battery capacity. A fully charged jumper or a launch charger can also help kick-start a stubborn engine. He also cautions that if the starter is faulty, it requires professional diagnosis and a qualified repair to restore reliable operation.
Another factor that can prevent starting in cold weather is condensation forming inside the exhaust system. In some cases, this moisture needs to be cleared manually, and the vehicle should be kept clear of moisture buildup before attempting a start after extended exposure to freezing temperatures. Drying brake components and ensuring the parking brake is fully released are important steps before leaving the car in the cold. These measures help avoid sticky brakes or other problems that can worsen starting difficulties.
In an earlier discussion, Yuri Parkhomenko, head of a testing laboratory, emphasized that using a booster remains one of the most effective methods to start a vehicle in severe frost. Boosters are starting devices that resemble standard phone chargers but are built with higher power capacity to deliver a rapid, concentrated burst of energy to the car battery when needed. This approach is particularly useful for older batteries or engines that have struggled to turn over in frigid conditions.
Across different markets, including Russia and other regions, car owners often highlight boosters as a practical, on-the-spot solution during winter. The overarching message is clear: in very cold climates, preparing for cold-starts with appropriate equipment and routine maintenance can significantly reduce the risk of a no-start scenario.
