When the cold arrives, drivers in Wrocław more often face problems starting the engine. Most often the culprit is the battery, because it supplies the energy needed to start the car and run the electrical systems. Low temperatures can significantly reduce its capacity and speed up wear. The SerwisUA team has prepared a detailed guide on how to look after the battery in winter so you can avoid unpleasant situations.
Why does cold harm the battery?
When the temperature drops below zero, the chemical processes inside the battery slow down. That leads to:
- lower capacity and voltage;
- a higher load when starting the engine;
- a risk of a complete discharge even in new batteries.
On average, at –20 °C a battery loses up to 40% of its power. If there is also wear of the internals or high humidity, the problem becomes even more serious.
How to prepare the battery for winter?
- Check the charge level Before the winter season it is recommended to test the battery at a specialist workshop. In Wrocław you can go to SerwisUA, where our technicians will diagnose it with professional equipment. The optimal voltage is at least 12.6 V.
- Clean the terminals Oxidised contacts reduce conductivity and increase the load on the battery. Use special brushes or a soda solution to clean them, then protect the terminals with anti-corrosion grease.
- Make sure the alternator works correctly If the alternator does not deliver enough current, even a new battery will quickly lose capacity. That is why it is worth checking the whole charging system.
- Protect the battery from frost To limit the effect of low temperatures, you can use a special thermal cover. It helps retain heat and protects the battery from sudden temperature swings.
How to use the battery in winter?
- Start the engine regularly. If the car sits unused for a long time, the battery gradually discharges. In winter it is worth starting the car at least once every few days.
- Avoid short trips. When the engine runs for less than 10 minutes, the battery does not have time to recharge.
- Switch off unnecessary electrical loads. Heated windows, heated seats and the audio system put a heavy load on the battery.
- Check the electrolyte level. In conventional batteries you should check the quantity and, if needed, top up with distilled water.
When is it worth replacing the battery?
If the car is hard to start, the lights dim during cranking, or the battery discharges even after a full charge — those are the first signs of wear. Average battery life is 4–6 years. In Wrocław you can always replace the battery at SerwisUA — we will match a suitable model to the make and type of your car.
