With the arrival of summer in Spain, air temperatures consistently rise to high levels, affecting not only people’s well-being but also the technical condition of vehicles. Drivers across the country report that in hot weather, their cars start more slowly than in other seasons. This phenomenon is linked to the specifics of how car batteries function under extreme heat.
High temperatures have a significant impact on batteries. In hot weather, chemical processes inside the battery accelerate, leading to increased self-discharge. Additionally, the heat causes the electrolyte to evaporate more quickly, which reduces the efficiency of electricity transfer. As a result, the starter needs more time to start the engine, especially if the battery is already aging.
Spain’s summer climate, especially in July and August, poses additional risks for vehicles. If the battery is worn out or not properly maintained, the likelihood of failure rises. Drivers may find that their cars won’t start at all, which is particularly inconvenient during vacations or long trips.
To avoid unpleasant situations on the road, experts recommend following a few simple rules. First of all, it is not advisable to leave your car in the sun for an extended period. It is better to use shaded parking or special protective covers. It is also important to start the engine regularly, even if the car is not used daily, to prevent the battery from becoming completely discharged.
A preventive battery check before the start of the summer season can help identify potential problems in advance. If you have any doubts about its condition, it’s better to replace the battery before the heat sets in. This will help you avoid unexpected breakdowns and ensure reliable engine starts even on the hottest days.
If, during the summer, the driver notices that the engine is starting more slowly, attention should be paid to the battery’s condition. At the first signs of malfunction, it is recommended to visit a service center or purchase a new battery, especially if you are planning a long trip across Spain.
Thus, the heat becomes a real challenge for car batteries. Following a few simple recommendations will help keep your vehicle running and prevent unpleasant surprises on the road during the height of the Spanish summer.
