Many car owners, when driving in winter, often face situation that battery is discharged and cannot start a fire. So why do car batteries drain easily in winter? How can we avoid battery loss? The editor is here today to talk to you about these battery issues.
There are many reasons why car batteries die in winter. The first of these is a decrease in charging speed. Due to increase in internal resistance of battery at low temperatures, charging speed of battery will be greatly slowed down. If battery is used for a long time and for a short distance, it will cause battery to lose power.
The second reason is that capacity of battery becomes lower. At low temperatures, chemical activity of battery decreases and capacity becomes smaller. Generally, best battery operating temperature is 25°C. Every time temperature drops 1°C, available capacity drops by about 0.8%. In addition, in a cold winter, after starting car, most of energy is spent on warming up engine, and remaining energy for charging battery is reduced, resulting in battery not being fully charged, so battery is often in a state of exhaustion.
So, how can we save ourselves if car battery is dead? If car has an emergency power supply, people use it to charge car. If not, we can ask for help from other vehicles that can start normally around us and charge battery with a charger. However, I would like to remind everyone that when connecting electricity, you cannot swap positive and negative poles, otherwise the battery will easily fail. If you cannot connect to electricity, you can only ask your insurance company or 4S shop for help.
In fact, if you want to avoid losing your battery in winter, most important thing is to stick to good driving habits. First of all, when starting car, you should pay attention to fact that start time of each use does not exceed 5 seconds, and optimal interval between two consecutive starts is 10-15 seconds.
Secondly, when you use your car in winter, try to avoid using powerful electrical appliances such as a powerful audio system, unusual lighting, etc. to reduce load on engine. In addition, when car is off, try not to use electrical appliances in car, and also do not turn on radio, air conditioner and other electrical equipment for a long time. Using electrical appliances with flame off also consumes battery power, which will discharge again after a long time.
In addition to developing good driving habits, you should also pay attention to battery maintenance while driving and check battery fluid level regularly. If there is not enough liquid in battery, timely add distilled water to appropriate level and check density of liquid in battery to keep liquid density within reasonable limits all time.
Generally speaking, life of a car battery is about 3-5 years, so everyone should properly maintain car battery and keep battery fully charged to prolong its service life.
