With the drop in temperatures, there comes a time when the car battery begins to fail more. Normally the car takes longer to start during the colder months, because the starting battery decreases its capacity at low temperatures, in fact, “the capacity of the battery decreases.” decreases for each degree the temperature drops», point out from ‘Choose quality, choose trust’ (ECEC).
However, this loss of starting capacity is due not to the cold, but to the self-discharge process suffered by the batteries with the high temperatures of summer, which has also been especially hot this year.
“Indeed, batteries fail in winter, but their deterioration occurs in summer”, they affirm from ECEC, and explain that “the battery is an active product that suffers wear over time, whether it is used or not, and therefore a at which point it loses all of its features and stops working. And it is that, despite the fact that the battery is stored in optimal conditions, it is continuously subjected to a self-discharge process by which, when temperatures are high, such as in summer, they cause greater self-discharge of the battery.
«In winter», they continue, «what happens is that the low temperature of the engine and the oil demand greater starting power from the batteries, which is sometimes not achieved given the deterioration they have suffered during the summer. In addition, the low temperatures typical of winter influence the chemical process that takes place inside the battery, which also affects starting and recharging.
Likewise, they point out that, in addition, “all the comfort functions typical of winter, such as seat heating or other heating systems, are also powered by the battery.”
Thus, to combat the effects of temperatures, the manufacturers of this component carry out important R&D work aimed at improving its autonomy and load acceptance above 30 percent, which reduces the risk of breakdown. or battery discharge, improving its performance even in extreme weather conditions.
