According to Battery.com.cn, many people in winter drive often have the feeling that the battery that has just been filled will be out of power in a short while. I feel that the electric image in the battery has been stolen, which is really a headache for many car owners. This is due to the low temperature in winter, and the battery capacity in a low temperature environment is much lower than that at normal temperature. Therefore, in the winter, it is very important to maintain the battery.
Why is the battery dead?
There are also functions and components running after the vehicle is turned off.
Many car owners think that after the switch is closed, the car is in a state of power failure. In fact, many devices are still in operation. The most common is the anti-theft system installed on many models. As soon as the car locks the door, the system begins to work, and the power consumed is much smaller than that of a headlight. However, in a few weeks, when the car does not start charging for a long time and the battery storage state is poor, the battery will be exhausted.
After the flameout, is the car completely still? In the traditional impression, as long as the car key is screwed to the closed state of the door, all the parts of the car are stopped. However, when the engine temperature is too high, even if the car is in a flameout state, the car key is pulled away from the car, and the cooling system will automatically start to cool the engine system. Only when the engine system temperature drops, the cooling system will automatically stop working, usually 3 to 5 minutes.
Forgot to turn off the lights after locking the car
Parking did not turn off the lights, and overnight, the battery was overworked and finally went on strike. Of course, many vehicles now have lock cars to automatically turn off the headlights, but there are still some cars that need to manually turn off the headlights, so be careful.
What are the precautions for using batteries in winter?
1. The battery will not be used for a long time, it will slowly discharge itself until it is scrapped. Therefore, the car should be started once every some time to charge the battery.
2. Avoid parking the car in the open parking lot for a long time. If it is parked for a long time, remove the battery and take it away to prevent the battery from freezing.
3. The storage capacity of the battery can be reflected on the instrument panel. When the ammeter pointer indicates that the storage capacity is insufficient, it should be charged in time.
4. The car engine is not easy to start in winter. The time for starting the car should not exceed 5 seconds, and the interval between restarts should be no less than 15 seconds.
5. When the electrolyte is deficient, it should be supplemented with distilled water or special rehydration solution. It should not be replaced by drinking pure water, because pure water contains many trace elements, which will have adverse effects on the battery.
6. Clean the battery terminals at regular intervals and apply special grease to protect the wiring harness. Always check the accessories and connection lines on the battery.
7. When driving daily, always check whether the small hole on the battery cover is ventilated. If the small hole of the battery cover is blocked, the generated hydrogen and oxygen will not be discharged. When the electrolyte expands, the battery case will be broken and the battery life will be affected.
8. It is forbidden to use automobile electrical appliances after the car is turned off. If the engine is used alone without generating electricity, it will cause damage.
9. Check the presence or absence of aging or short-circuiting in all parts of the circuit to prevent the battery from being decommissioned early due to excessive discharge.
10. Generally speaking, the battery life of a car is about 2 to 3 years, but the modified car equipment will often damage the battery life. In winter, it is necessary to check whether the battery is running normally.
Specific methods of maintaining the battery:
1. Wipe the outside of the battery with a damp cloth, and wipe off the dirt, oil, white powder, etc. on the panel and column head. Frequent scrubbing of the stigma of the battery, not only the white acid-etched powder will not accumulate on it, and the battery life will be longer than expected.
2. Open the water cap of the battery and see if the water level is in the normal position. Generally, there will be upper and lower limit markings on the side of the battery for your reference. If the water level is found to be lower than the subscript line, distilled water must be added. The water should not be added too much. The standard is the most suitable for the middle of the upper and lower marking lines.
