Why is the car battery easy to break down in cold weather? These three habits hurt the battery!

Autumn and winter are also the high incidence of problems in automobile batteries. Many car owners often fail to catch fire after parking for a few days. Then, why is it easy for car batteries to die when the weather is cold? It is usually replaced every few years. What are the signs before the battery fails? What if the power suddenly goes out and the fire stops?

* Why are car batteries more afraid of cold?

"Afraid of cold" is the * * * of the battery. Not only car batteries, but all batteries will shorten battery life at low temperature, such as your mobile phone.

Generally, the optimum temperature of automobile battery is 25℃, and the available capacity of battery will decrease by about 0.8% every time 1 decreases, and the capacity will recover when the temperature rises. In addition, in the low-temperature environment, the heating functions of seats, rearview mirrors and steering wheels, as well as many high-power devices such as glass defogging, greatly increase the opportunities and pressure of electricity use.

In addition, the temperature will also affect the life of the battery. Related research found that batteries that can be used for 3 years at room temperature can only be reduced to less than 2 years at -20℃.

* Which habits are the most harmful to the battery?

Weather factors are uncontrollable, but these habits are most likely to damage the battery and reduce its service life during daily car use:

1, still using air conditioners and electrical appliances after the flameout.

After the car stops, use air conditioning, listen to music for a long time, or turn on the headlights. It is easy to drain the battery and damage it.

2. Start the car frequently

When the car is started, the starting time shall not exceed 5 seconds each time, and the interval between restarting shall not be less than 15 seconds, otherwise the battery will be damaged by excessive discharge due to uninterrupted use of the starting opportunity.

3. The vehicle is parked for a long time and not used.

The battery will naturally discharge, and it will be dead after two or three weeks of full charge. After more than two months, the battery will completely release the maximum power and its service life will be greatly reduced. So, if you don't use the car for a long time, remember to disconnect the battery cord, or start the car every once in a while and let the generator charge the battery. Daily when the dashboard shows that the battery is low, it is necessary to charge the battery in time.
