As the temperature drops gradually, many people have to wear long-lost autumn clothes and trousers to keep out the cold, and those friends who don't pay attention to keep warm are easily frozen. So is our car. As the temperature drops, many classic cars are prone to some minor problems, among which the ignition of several batteries is the most common. The following is a little knowledge about battery maintenance to help car owners avoid battery power loss as much as possible.
As we all know, the battery is the energy source for starting all electronic equipment and engines in the car, and it is the core component of the whole power supply system. With the improvement of automobile electronization.
There are more and more electronic devices in the car, and the power supply burden of the battery is getting heavier and heavier. However, no matter what kind of chemical battery, its capacity will be affected by the number of cycles and temperature. With the increase of battery cycle times and the decrease of temperature, the battery capacity will gradually decrease and the discharge capacity will also decrease, so winter is the high incidence period of battery problems. If the vehicle battery is frequently cut off in winter, it is basically caused by battery aging damage.
The service life of the battery is different according to the owner's car habits. Generally speaking, the service life of most car batteries is less than 6 years, and some car owners with excellent electricity habits can extend the service life of batteries to 6-8 years.
What can I do to keep the battery away from power failure or even failure?
Try to avoid using electrical appliances in the car for a long time before the engine starts. Before the engine is started, all the power of the vehicle comes from the electricity stored in the battery. If you use the electric appliances in the car for a long time, the battery will not be enough to start the vehicle.
If you must use electrical appliances in the car for a long time, try to start the engine every once in a while and let the generator charge the battery.
Turn off all electrical appliances of the vehicle before turning off the engine. Some models are not equipped with the function of "automatic power off after flameout", so the vehicle will continue to be powered on after locking. If you forget to turn off the vehicle electrical appliances when you get off the bus, it is easy to cause the battery to be too low to start. Generally speaking, the battery is dead, because the light is not turned off.
In addition, the driving recorder or GPS positioning device may also be the culprit leading to power failure. In order to ensure the parking safety of vehicles, some car owners will choose a driving recorder with parking monitoring function, and this recorder usually uses the way of directly obtaining electric energy from the battery. After the parking monitoring mode is turned on, the recorder will keep working and continue to consume battery power. If the parking time is too long, it will lead to battery loss. The same is true of GPS positioning equipment.
Turn off the air conditioner before turning off the fire. Air conditioning is essential when the weather is hot or cold, but many friends don't turn off the air conditioning when parking. When the vehicle is re-ignited, the air conditioning system will automatically start with the ignition of the vehicle, resulting in an instantaneous high load of the battery, which will aggravate the aging of the battery in the long run.
Avoid starting the vehicle frequently for many times. In cold areas in winter, many vehicles will be difficult to start because of the viscosity of engine oil, and it is usually impossible to ignite successfully at one time, so some car owners will start their vehicles frequently for many times. However, when starting the vehicle, the battery will discharge with huge current to start the vehicle. Frequent high-rate discharge will not only lead to a sudden drop in power, but also lead to a rapid rise in battery temperature, which is very harmful to the battery. (Except for automatic on-off bottle)
Don't park the vehicle for a long time, because the battery has the characteristics of self-discharge, even if all the electrical equipment on the vehicle remains closed, the battery power will be "quietly" reduced. If the vehicle is parked for a long time and the battery is too low, it will not only cause the vehicle to be unable to start again, but also damage the life of the battery. If it is really necessary to park for a long time, the negative connection wire of the battery can be removed to reduce the self-discharge speed of the battery as much as possible.
Do not over-modify the vehicle circuit. Generally speaking, the main modification of vehicle electrical appliances is the modification of sound system. Some music enthusiasts will modify the sound system with high sound resolution for vehicles.
However, the power of this audio system is relatively large, which undoubtedly increases the burden on the battery and accelerates the aging speed of the battery. In addition, modifying the circuit will increase the risk of short-circuit spontaneous combustion of the vehicle.
Check the battery regularly. In order to have a clear understanding of the aging degree of the battery, check the battery as much as possible during maintenance, and the inspection period should be shortened appropriately with the increase of vehicle age. If the battery voltage is found to be abnormal, we should be highly vigilant and take countermeasures to avoid the battery being suddenly hit and affecting the normal use of the car.
It should be noted here that the voltage of the battery is not constant, but changes in an interval. For most 12V batteries, the voltage should be between 13- 14.4V when the engine is started and around 12V when the engine is turned off. As long as the voltage is within this range, it means that the battery is in a normal state. When the battery voltage is obviously lower than the normal value, it will be difficult or even impossible for the vehicle to start.
As a consumable part, battery will inevitably encounter power failure in daily use. If the battery voltage changes abnormally, we can keep an emergency starting power supply in the car at any time to prevent the car from breaking down.
Ensure that the vehicle battery can start normally when the power is off. If the battery of your car has been abnormal, we still suggest going to a professional repair shop to replace the battery as soon as possible to prevent possible power loss.
When choosing a new battery, we don't have to choose the original battery, and it is also very reliable to choose some affordable big brand batteries.
