What s going on with the battery of a newly bought car that starts poorly

Consider the following reasons:

1.Pay attention to the battery: Now the car is commonly used maintenance-free battery, and it is also necessary to regularly look at the power display inside:

Under normal circumstances, green means that the power is normal, white means that the battery needs to be charged and maintained, and red means that the battery is out of power (some indicate this: green means qualified, black means power loss, and white means that the battery is damaged and needs to be replaced). The lifespan of the battery is generally about two years.

If the battery level drops, it should be replaced in time.

2.Pay attention to the throttle.

Valve body, idle valve: throttle valve body, idle valve due to carbon stagnation caused by the difficulty of starting, if the vehicle using the idle valve can lightly step on the accelerator and start again can catch fire, but the oil will be immediately extinguished, so it is best to go to the repair shop in time to do a cleaning and maintenance. In addition, when doing maintenance, be sure to change the air filter frequently.

Northern air dust multi-air filter.

It should be replaced every 10,000 kilometers, and if it is a sandy road, it should be more timely.

3.Fuel pressure: In order to ensure the normal start of the engine, the residual oil pressure of the fuel system after the engine is turned off cannot be lower, otherwise the fuel injector will not be able to inject enough fuel to ensure the start if the pressure is insufficient.

At this point, if the ignition is turned on repeatedly, the fuel pressure will return to normal, and the start will be much easier. But it's best to find a professional maintenance person to check the fuel system and troubleshoot.

There are two possibilities: 1: Your battery may need to be refilled with battery water, or the battery is not working, and the battery needs to be replaced. The main reason for the battery car is the battery.

2: The carbon brush needs to be replaced, or the carbon brush is used up, the controller is generally not so easy to break as long as there is no water, and then it is the reason for contact, because when you run, the shock absorption performance is not good, and the line is loosened.

If you start several times in a row (do not let the car start, the interval time is greater than 15), feel that the force is about the same each time, the battery is no problem, check the contact between the battery pile and the line, if it is hot, you can determine the poor contact. One time is not as good as one time, and the battery is less electric. Charge.

The reasons why the car battery is always out of power are:1. Forget to turn off the lights, air conditioner, and radio.

2. Use high-power electrical appliances when idling, such as high-power audio.

3. Start too often.

4. Battery leakage caused by other reasons.

The battery has a service life, usually pay more attention to whether the battery is healthy when using, if there is leakage and other phenomena, it means that the battery should be repaired or replaced in time.

Car battery maintenance method:

1. When the car's battery is not suitable for a long time, start the car once in a while to charge the battery.

2. Do not leave the car in the open-air parking lot for a long time, if it is parked for a long time, you need to remove the battery and take it away to prevent the battery from being damaged by icing.

3. The storage capacity of the battery can be reflected on the dashboard.

4. When the ammeter pointer shows that the storage capacity is insufficient, it should be charged in time.

Hello, try to take a battery first, generally the battery problem, the use of the car, the most common problem is that the battery is not powered, generally check the battery voltage between 11 volts and 13 volts, if possible, use the battery detector to check whether it needs to be replaced, or charge, in addition, also check whether the generator charging voltage is between 13 and 15 volts after starting, whether it is normal, and then check whether the static power consumption is normal (the negative current after locking the car, can not be greater than 40 mAh) If it is exceeded, it is necessary to check whether there is a leakage [there is a problem with the car, ask.

Car Master. 4S shop professional technician, 10 minutes to solve. 】

If the first type of battery is damaged, the only way to replace it is to replace it with a new one. For the second type of battery, first check whether the water level of the battery meets the standard, and if it does not meet the standard, it will also cause the battery to not store power. Just add it.

I suggest that you don't blindly go to the battery replacement and go to the repair shop to find an electrician to check whether your generator is well charged.

2. Check whether your car appliances are running out.

Charge in a timely manner.

1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

2. Emergency power supply: This is a new type of power bank like a thing, there are two kinds of lead-acid and polymer lithium battery, which can help the vehicle with a loss of power to start, and can also have lighting, charging mobile phones and multi-functional supplies used with an inflatable pump to inflate the car. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help.

Be sure to charge it in time after use and keep it full of power to deal with emergencies.

3. Positive, first connect positive: first turn off all the electrical equipment on the car, so that the key is in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red number is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp the positive pole of the battery of the non-tram, and the other end of the clip clamp to firmly rescue the positive pole of the battery of the car. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

4. Negative connection negative, then negative: After the red positive electrode is connected, take out another wire, first clamp the negative electrode of the electric car battery, the negative electrode is generally black, and then pinch the other end of the clamp, from beginning to end the clamp do not touch other places, to clamp the negative electrode of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the iron conductive place of the whole vehicle is basically the negative electrode, which is commonly known as the tie iron, if the negative electrode is connected first, when the positive electrode is connected, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle first ignition to charge the battery, and then no tram enters the vehicle to open the key, at this time the instrument light will be lit up smoothly, and then try to ignite not more than 5 seconds, if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then no tram is ignited again, if the starter is no problem, there is oil in the car can generally start smoothly in the spike loss, after the family Qin no electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

This is the aging of the starter of the vehicle, and the starter needs to be replaced to solve the silver belt fault, and the aging starter is weak in rotation, so the ignition is not energetic.

Also look at the carsGearsIs it hung in the P gear, if the gear is not in the P gear, the vehicle can not ignite, this is actually the self-protection mechanism of the vehicle, not a mechanical failure, we only need to pull the gear back to the P gear to use normally.

For diesel engines, low body temperature in winter will also make it difficult for the vehicle to start, so we only need to screw the key to the energized position, and the vehicle can start normally after the heating light on the instrument disappears.

Car battery maintenance:

1. The car should be driven regularly:

Especially for new cars, it is recommended that the owner drive it regularly, the vehicle is parked for a long time so that the power in the battery slowly decreases, after a long time, it is easy to lose power, you can drive out for a period of time every few days, let the car battery be charged, try to keep the car battery in a full state, it is best to keep it at more than 20 minutes of driving time.

2. Try not to use electricity after the vehicle is turned off

Listening to songs after turning off is a more common phenomenon in the process of daily car use, especially when waiting for others, many people like to listen to songs, in the state of flameout, the car consumes the power supply of the battery, if it is used for a long time, the power in the battery may be exhausted, and the phenomenon of not being able to start the car is not moving, it is recommended that the owner does not use electrical equipment after the vehicle is turned off.

3. Clean the battery regularly

In the daily driving process, you need to clean the battery of the car, you can use a rag to wipe the dust, oil, white powder and other leakage dirt of the panel, positive and negative poles, do not use a wet cloth, if you do not handle it well, it is recommended that the owner go directly to the 4S shop.

Or a professional repair shop to deal with it.

This is the aging of the starter of the vehicle, the starter needs to be replaced to solve this fault, the aging starter is dull and rotates weakly, so the Sakura is not energetic when it hits the fire, the specific operation steps are as follows:

1. Disconnect the battery electrodes.

2. Unplug the plug that activates the letter Songkuan.

3. Disconnect the battery from the starter connector.

4. Remove the two screws in the picture.

5. Remove the starter.

6. Install the new ones in reverse order and you're done.

Notes:1. The starter should use the same model.

2. Be sure to disconnect the battery during operation.
