How much is the normal power of the car battery

The battery capacity of a car is average It can store up to 1200W of electricity. In fact, it should be judged according to the size of the battery capacity. Generally speaking, the battery of 40~100AH is the most. Take the 100AH battery as an example, theoretically it can store 12V*100AH=1200WH.

The power of the car battery can generally store up to 12,000W. In fact, it should be judged according to the battery capacity. In general, the battery with the most 40~100AH is 1000AH. For example, in theory, it can store 12 power V*100AH=1200WH. According to the voltage judgment, the no-load voltage is 13V. The load voltage is not less than 11V.

The normal value of car battery detection is 12V. When testing, if the vehicle is stationary and not started, the voltage should be 16~18V, which is a normal value.

Normal. The normal range of car battery power is 50 to 75%. When the car battery power reaches 70%, it means that the battery is still supplied with electricity, which can start the vehicle normally and supply electricity to various equipment and systems.

In practice, it should be judged according to the size of the battery capacity. In general, 40~100AH batteries are the most common. Take 100AH as an example, theoretically, it can store 12V*100AH=1200WH. Judging from the voltage: the no-load voltage is about 13V, and the load voltage is not less than 11V, which is normal.

60% of the car's battery is abnormal. Under normal circumstances, the power of the car battery should be 100%. If the battery can only be charged to 60%, it means that there has been a problem with the battery, which is due to the vulcanization of the pole plate or damage to the charger.

What is the car battery power? Look at

There are many ways to check the battery power, such as the color of the electric eye, and it can also be measured with special equipment. All batteries have electric eyes. The function of this electric eye is to allow users to understand the status of the battery by observing the color of the electric eye. The color of the electric eye of different manufacturers' batteries is different, which is explained on the battery shell.

The accurate power of the car battery cannot be seen. We can only judge whether the battery is charged through some phenomena. To be precise, it is to judge what state the battery is in.On the surface of the battery, there is an observation hole (also known as the electric eye), which can judge the current state of the battery by observing the observation hole of the battery.

The battery power indicator is also known as the electric eye. The black display indicates that it needs to be charged, the green indicates that it is good, and the white display indicates that the liquid is insufficient and needs to be replaced.

The way to check the battery power in the car is: check it through the color of the electric eye; let professionals use a multimeter to measure the battery voltage; many cars have a power display, and you can check the remaining battery power on the dashboard of these cars.

The car checks the power of the battery on the dashboard. The way to judge that the car battery is out of power is: check the power indicator of the battery; measure the static voltage of the battery; open the engine cover and check the observation hole of the battery; rotate when the engine is started, and the instrument light on the dashboard flashes.

First of all, we need to open the hood of the car and find the battery. The battery is usually located under the hood, which is a rectangular box with two electrodes on it. Then, we can see a transparent LCD display on the battery, which will show the remaining power of the battery.

How should we look at the power of the car?

1. Green or blue indicates good condition; black or red indicates that it needs to be charged; white indicates that the electrolyte is insufficient and the battery needs to be replaced. The color of the battery observation holes of different manufacturers may be different. Generally speaking, there will be an explanation on the surface of the battery.

2. The engine can't start: The moment the car starts, the battery will have a large current to drive the engine, but if the battery can't reach the battery, the engine won't start.At this time, the battery failure on the dashboard will light up, prompting that the battery is out of power.

3. Check whether the battery is new or refurbished (it is recommended to buy it from a regular place). Check whether the generator is normal. Find a circuit repairman to check the whole line of the car to see if there is any leakage. To prevent the car from suddenly ringing out of power, the best way is to pay more attention to the "help signal" sent by your car.

car under-power sign

If the horn is not as loud as before, it means that the battery is running out. You can also turn on the headlights for inspection. If the light is white, it means that the battery is normal; if the light is red and dark, it means that the battery is low.

There will be a symbol like a battery on the dashboard, with a plus sign on one side and a minus sign on the other.

If the car is not fully charged, a sign similar to a storage battery will light up on the dashboard, and the engine fault light will also light up. Under normal circumstances, the battery status indicator light will automatically turn off when the engine is started. The car is not fully charged enough to start the car. With a little fire, the engine will make a "squeaky" sound.

The white light indicates that the battery is normal. If the light is red and dark, it means that the power is insufficient.

There are the following signs for whether the car battery is out of power: if it can't start once or twice, it means that the voltage may be insufficient; after the battery has been used for more than a year, you can press the horn first when starting the car. If the horn is not as loud as before, it means that the battery is almost out of power; you can also turn on the headlights for inspection. Check.

How to check the remaining power of the battery on the car

1. There are many ways to check the battery power, such as looking at the color of the electric eye, which can also be measured with special equipment. All batteries have electric eyes. The function of this electric eye is to allow users to understand the status of the battery by observing the color of the electric eye. The color of the electric eye of different manufacturers' batteries is different, which is explained on the battery shell.

2. The way to check the battery power in the car is: check it through the color of the electric eye; let professionals use a multimeter to measure the voltage of the battery; many cars have a power display, and the remaining power of the battery can be checked on the dashboard of these cars.

3. Introduce a few simple methods: press the horn directly. If the horn does not sound before, it means that the battery is low.You can also turn on the headlights for inspection. If the light is white, it means that the battery is normal. If the light is red and dark, it means that the power is insufficient.

4. First of all, we need to open the hood of the car and find the battery. The battery is usually located under the hood, which is a rectangular box with two electrodes on it. Then, we can see a transparent LCD display on the battery, which will show the remaining power of the battery.

5. For example, 12V60Ah charging method: use constant voltage current limit method for charging, constant voltage 18V current limit 15A to charge for 16 hours, and then charge with 3A constant current for 4 hours, a total of 20 hours.

6. Another method is to use a voltmeter to detect the battery voltage. The voltage is 16V, and the power is more than 95%; below 18V, the battery is out of power;If it is below 6V, the battery will be scrapped.
