How about the battery? How to determine the quality of the car battery

The length of the service life of the automotive battery, on the one hand, depending on the structure and quality of the battery, and on the other hand, it is closely related to the daily maintenance of the owner. What habits in daily driving will accelerate the damage of the battery? The vehicle does not open for a long time. Since the battery is self-discharge, if the vehicle is not available for a long time, it is possible to cause the battery to consume light, and finally can't start the vehicle or damage the battery.

Get off does not turn off the light or car equipment. The parking forgetting the lanterns will not be more common on the second day, and other vehicles in other vehicles will also lead to battery depth loss. This has a certain damage to the battery.

Do not turn off the air conditioner before the vehicle is turned off. This will enable the car to turn on the next startup, which will cause too high in the instantaneous power of the vehicle, the battery load is too large, and the battery is a loss for the battery. Do not fire listening to the song open air conditioner.

Many people stop the car, listen to the song and blow air conditioner, but in order to save oil, it will often turn out the engine, so that it is very likely that the battery power consumes light, can't finally start, and long-term easy to scrap the battery in advance. The battery of the car is an important unit of the automotive electrical system. If the battery has failed, the most direct performance is that the vehicle cannot start, especially the automatic block, and when the battery voltage is low, it can only use the over-electricity method.

kind of hard. How to prevent this embarrassing situation outside, then we must learn to properly choose high quality automotive batteries in usual use, while timely understanding your car's battery condition and paying attention to daily maintenance. Battery is good and bad discrimination method: the battery's good decision has a dedicated battery measuring instrument, but the general user has few such instruments, and there is only one multimeter.

In the following maintenance, it is judged that the battery is good and bad. Summary, for reference. Judging from the appearance, there is no deformation, protruding, leakage, cracking, fried, screw connection, etc.

The load measurement If the appearance is not abnormal, the UPS operates in battery mode with a certain amount of load. If the discharge time is significantly shorter than normal discharge time, after 8 hours, it is not necessary to return to normal alternate time, determine the battery aging. Battery discharge mode Measurement: Measure the end voltage in the battery pack, if one or more battery terminal voltage is revealed above or lower than the nominal voltage (nominal voltage 12V / section), determine the battery aging.

Monogram: The charging voltage of each battery end in the battery pack, if the charging voltage of one or more batteries is revealed above or lower than other voltages, the battery aging. The total voltage of the battery pack: The total voltage of the battery pack is significantly lower than the nominal value (the Nomility value of the C1K battery pack is 36V), and the charging is not allowed to return to the normal value, even if it is restored to the normal value, discharge time Do not reach the normal discharge time, determine the aging of the battery. Battery boot measurement: UPS does not boot, do not pick up the market, first measuring the total voltage of the battery pack, at this time, the voltage may be between 36V-40V, which belongs to the normal value, the cliff does not leave, always stare at the instructions of the multimeter, then After connecting the machine, if the battery total voltage is down to 30V or even ten volts, the UPS is automatically shut down, and the voltage is immediately restored to the original value.
