How to measure the battery life How to test the life of the car battery

1. Voltage measurement, measure the voltage of the battery through the battery measuring instrument or universal meter, under normal circumstances, the no-load voltage of the battery is about 13 volts, the full-load voltage is generally not lower than 12 volts, and the starting voltage should not be lower than volts. If the battery voltage is low, it may be difficult to start or unable to start the vehicle;

2. Press the horn to check, after the battery has been used for more than a year, you can usually press the horn first when starting the car, if the horn is not as loud as before, it means that the battery is about to run out;

3. Headlight check, turn on the headlights for inspection, if the light is white, it means that the battery is normal, if the light is red and dim, it means that the power is insufficient.

Hello! The current technical status of the battery can be judged by the battery detector, and the battery life can be further roughly judged. The life of the lead-acid battery on ordinary fuel vehicles is about 3 years, and the actual life is related to the manufacturing quality of the battery and the usual maintenance level. Thank you!

Hello, the easiest way is to measure the voltage.

1. Measure the voltage of the battery through the battery measuring instrument or multimeter. Under normal circumstances, the no-load voltage of the battery is about 13 volts, the full load voltage is generally not lower than 12 volts, and the starting voltage should not be lower than volts. If the battery voltage is low, it may be difficult or impossible to start the vehicle.

2. In addition, after more than a year of use, the battery will be started at ordinary times.

How many years does a car battery last? Teach you a few tricks to check the battery, and replace it in time when these conditions occur.

Generally, the service life of the battery is 2-3 years, and it can be replaced directly when the service is reached.

Ways to check battery life:Tools Raw materials: apples 11,.

1. Tap Settings, go to iPhone, tap Settings, enter Settings, and pull down the screen.

2. Click on the battery option, and find the battery option under the settings to enter, as shown in the figure below.

3. Select Battery Health, and click Battery Health on the Battery interface, as shown in the figure below.

4. Check the life, you can see the percentage of remaining life in the battery health interface, which is generally less than 80% and needs to be replaced, as shown in the figure below.

Car batteries are generally 2 to 3 years old!

At present, there are two kinds of detection of battery life, one has an observation hole, which can be seen through the observation hole, which is divided into green, black and white. Green represents health, black means don't charge due to lack of power, and white means that the battery is about to hang up. The other is a cigarette lighter charger with a voltage display.

As soon as the battery power is low, the cigarette lighter charger starts flashing. Depending on the model, if the battery voltage is lower than 11 volts, the car may not start. Therefore, the health status of the battery can also be judged by the ignition voltage in the car.

The battery condition is relatively good, in the case of power-on, the battery voltage will not drop quickly, and the battery condition is not very good, the voltage will drop quickly. Under normal circumstances, the car without automatic start and stop is slightly better maintained, and it is not a big problem to use 5 or 6 years, and the life of the car with automatic start will be shorter by 3 or 4 years. Therefore, according to the service life, combined with the situation of use at that time, it can basically be judged whether the battery is going to be hung.

If you want to replace the battery, you must pay attention to the above parameters of the battery. First of all, the most important parameters, one is the front voltage parameter, the second rear capacity parameter, ordinary passenger cars are basically 12 volts, this one can never be changed. Then the second rear capacity parameter as long as the battery pit can be put down, the back capacity must be the larger the better, the bigger the more expensive, if the back capacity is smaller than the original battery, it will lead to insufficient battery power supply or battery endurance decrease, the battery is easy to hang up, or burn some other spare parts on the car.

As for the above parameter 6, it represents 6 battery cells, Q represents the car starting battery, W represents the maintenance-free storage battery, and 60 is the capacity corresponding to the following 60. Through Brother Meow's personal experience, if you don't start the engine, you can turn on the headlights to take a look, or press the horn, if the brightness of the headlights is not very bright and the horn is not loud, then it means that the battery may be about to die, it is recommended that you can replace the battery in advance.
