Is there a mobile charger that doesn t use power when the car battery is out of power and parked in

With a 12V car battery charger you can, about charged.

In three or five hours, you can start the car. Do not remove the battery, otherwise, all functions on the car will fail, especially the door lock, in case it is locked, it will not be opened if there is no power.

You can remove the battery and charge it yourself. When charging, it needs to be fully charged, because if the battery is not fully charged, the battery feeding may not be able to drive the car.

1. Explanation of battery: Battery, also known as battery, is a device that converts chemical energy into electrical energy. When the vehicle is ready to start, the battery will be discharged to provide power to the starter, and the starter will drive the flywheel and crankshaft to rotate, so as to start the vehicle.

When the engine is underpowered or not started, it provides power to the interior appliances such as the audio system and lighting system, and when the engine starts to supply power normally, the battery collects and stores the electrical energy for use. It uses a lead plate filled with spongy lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 22 28% dilute sulfuric acid as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy.

2. The working principle of the battery: it uses a lead plate filled with spongy lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 22 28% dilute sulfuric acid as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy.

When the battery is discharged, the metal lead is the negative electrode, which undergoes an oxidation reaction and is oxidized to lead sulfate; Lead dioxide is the positive electrode, which undergoes a reduction reaction and is reduced to lead sulfate. When the battery is charged with direct current, lead and lead dioxide are generated at the two poles, respectively. After the power supply is removed, it returns to its pre-discharge state and forms a chemical cell.

No, there is a device called emergency starting power supply, which is actually a battery and two wires. You can borrow a passing car, take a battery, and go to the repair shop for an inspection.

1. When the car battery is empty, it can be charged with a charger.

2. The capacity is printed on the shell of the battery, such as 12V48Ah, which means that the battery voltage is 12A, and the capacity is 48Ah, A means amperage, and H means hour, which can be simply understood as fully charged, it can be discharged at 48A current for 1 small (it is actually impossible to discharge large current for a long time), or ampere current discharge for 10 hours. That's what capacity means. Generally, C is used.

3. Charging with an external charger is generally 14 to 15 hours at a speed, taking the above 48ah battery as an example, after using up the electricity, it can be fully charged for 14 hours with current.

4. It is impossible for the general battery to run out of electricity, the voltage at both ends of the battery can be detected, and the 12V battery is fully charged.

Summary. If you still can't start after two hours of charging, then your battery is out of charge and you need to replace it.

It's been two hours now, and it's still like that.

Can the car battery be charged when it is out of power The car battery is out of power, it can be charged, as follows: 1. As long as the engine starts, the rotten shirt generator can be charged when it works, if the vehicle is not faulty, the battery will be charged after the engine starts, and the power consumed can be filled in about 3-5 minutes; 2. Like our mobile phone, charging takes time, if the vehicle runs for a long time for three or five minutes of collapse short distance, then the generator charge can not make up for the loss of electricity when the vehicle starts, for a long time, the battery has been in a state of power loss, which will lead to the shortening of the battery service life, and often the situation that the vehicle cannot be started; 3. If it is a vehicle that often runs short distances, it is recommended to occasionally run down the long road, or often use a special battery charger to charge. @2019

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 movement of the silver before starting, so the car battery connection line must be bought with 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 to negative, after negative: After the red positive electrode is connected, take out another wire, first clamp the negative electrode of the tram 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 pole 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 dismantle the remaining regret orange 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, then the instrument light will light up smoothly, and then try to ignite not more than 5 seconds, if it fails to start smoothly, lightly step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then no tram is erected again for ignition, if the starter is no problem, there is oil in the car can generally start smoothly, after the non-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.

Yes, car batteries.

When there is no electricity, you can use the charger to charge the battery at home, usually the battery capacity of the family car is about 60ah, and the charging current required is the battery capacity.

of tenths, which is 6a. Charging at this current, it can be fully charged in about 3-5 hours, and if it is charged with low current, it will take about 10 hours to be fully charged.

The car battery, also known as the battery, is a kind of electric Zhengxian Chunchi, and its working principle is to convert chemical energy into electrical energy. Usually, people refer to batteries as lead-acid batteries.

That is, an electrolyte, mainly made of lead and its oxides.

It is a battery with sulfuric acid solution.

Battery maintenance, the battery is most afraid of low temperature, in the low temperature environment, the battery capacity.

It is much lower than the capacitance at room temperature. Therefore, we should check and maintain it in time, and pay attention to it in daily life:

1. Avoid parking the car in the open-air parking lot for a long time, if it is parked for a long time, the battery must be removed and taken away to prevent the battery from being damaged by icing.

2. The car engine is not easy to start in winter, and the time to start the car each time should not exceed 5 seconds, and the interval between starting again should not be less than 15 seconds. In the case that the ignition is still not ignited after multiple starts, it should be taken from the circuit and the ignition coil.

or oil circuits and other aspects to find the reason. Avoid multiple uninterrupted starts, which can cause the battery to burn out due to over-discharge.

3. Automobile batteries.

It should be charged frequently, and the battery will slowly discharge itself until it is scrapped after not being used for a long time, so the car should be started every once in a while to charge the battery.

4. Clean the terminal post of the battery every once in a while, and apply special grease to protect the wiring harness. Always check the accessories and connections on the battery.

5. It is forbidden to use automotive electrical appliances after the car is turned off, and the engine will cause damage to the engine if it does not generate electricity.

There are two ways to charge a car battery: one is fast charging and the other is slow charging.

Fast charging (constant current charging): Many car owners think that fast charging can save time, it only takes 3-5 hours; In fact, fast charging only activates the surface of the battery quickly, but in fact the inside of the battery is not fully charged.

Slow charging (constant voltage charging): There is also a charging method for car batteries, for slow charging, the charging time is 10-15 hours, those deep loss batteries must be charged slowly, otherwise the charging time is not enough, the charging amount is insufficient, which directly affects the driving performance of the car.

Chen Yalan.

Yes, the car battery should be charged in time when it is dead. At home, you can charge the battery with a charger. Typical battery capacity of a family car.

At around 60Ah, the required charging current is one-tenth of the battery's capacity, which is 6A. It generally takes about 3-5 hours to fully charge with this current, but it takes about 10 hours to fully charge with a small current.

A car battery, also known as a storage battery, is a type of battery. It works by converting chemical energy into electrical energy. Usually, people refer to batteries as lead-acid batteries.

That is, batteries mainly made of lead and its oxides, electrolytes.

It is a sulfuric acid solution.

Battery maintenance, the battery is most afraid of low temperatures. At low temperatures, the capacity of the battery is much lower than at room temperature. Therefore, we should inspect and maintain it in a timely manner, and pay attention to:

1.Avoid parking for long periods of time in open parking lots. If parking for an extended period of time, remove the battery and take it away to prevent the battery from freezing and damage.

2.Car engines.

Not easy to start in winter. The time to start the car should not exceed 5 seconds each time, and the interval between starting again should not be less than 15 seconds. If the ignition is not started many times, it should be from the circuit, the ignition coil.

or oil circuits and other aspects to find the cause. Avoid repeated starts without interruption, which can cause the battery to burn out due to over-discharge.

3.Car batteries should be charged frequently. If it is not used for a long time, it will slowly discharge itself until it is scrapped. Therefore, the car should be started every once in a while to recharge the battery.

4.Clean the terminals of the battery regularly.

And apply special grease to protect the wiring harness. Always check the accessories and cables on the battery.

5.It is forbidden to use the car's electrical appliances after the car is turned off. If the engine uses batteries alone and does not generate electricity, it can cause damage.

There are two ways to charge a car's battery: one is fast charging and the other is slow charging.

Fast charging (constant current charging): Many car owners think that fast charging can save time, only 3-5 hours; In fact, fast charging only quickly activates the surface of the battery, but in fact, the inside of the battery is not fully charged.

Slow Charging (Constant Voltage Charging): There is another way to charge car batteries, which is slow charging. The charging time is 10-15 hours. Those batteries that have suffered heavy losses must be recharged slowly. Otherwise, the charging time is insufficient and the charging amount is insufficient, which will directly affect the driving performance of the car.
