Battery maintenance misunderstanding

Date:Apr 29, 2019

The battery is the energy source of the car, and its performance directly affects the normal operation of the car. Because some owners and maintenance personnel do not pay attention to the use and maintenance of the battery, they do not understand, resulting in shortened battery life and even damage other electrical equipment.


Here are some misunderstandings encountered in daily work:


One: the new battery is not charged for the first time


The first charge of the battery is called the first charge, and the initial charge has a great impact on the battery life. If it is not charged, that is, if the water is used directly, the battery capacity is not high and the life is very short; if it is directly charged, the life will be shortened. Usually, the initial charge of the battery is installed after the filling of the electrolyte, and charging with a small current for about 1 hour.


Second: ignore the vent of the battery


The vent hole on the new battery cover is generally sealed. The adhesive paper must be removed during use. Otherwise, the gas hole cannot remove the gas during the chemical reaction, and the explosion may occur due to excessive pressure.


Third: the battery is too free to add distilled water


Usually, after the battery is filled with water, the vehicle must be operated for a period of time, and the battery is charged by the generator to fully mix the distilled water with the electrolyte, and the performance of the battery is not affected. On the other hand, if distilled water is not used, the distilled water and the electrolyte cannot be sufficiently mixed, which may cause self-discharge of the battery or damage the polarity of the battery.


Fourth: the battery charge capacity does not match the engine


The current to start the engine is typically 150-200A, and even at low temperatures up to 300A. If the charge capacity does not match the engine and the charge of the battery is small, the resistance will increase when starting, and the battery will discharge severely, which will accelerate the reaction of the active material with sulfuric acid per unit time, so that the battery temperature is too high, and the plate causes the load to deform and bend. , causing the active material to fall off, the early damage of the plate, so that the battery life is greatly reduced. If the car uses a large-capacity battery, the active material cannot be fully utilized, resulting in a decrease in economy. When the battery is loaded, it is determined according to the power, voltage and load of the power equipment. Therefore, when swapping, it must be noted that the charge capacity matches the engine.


The battery is the nerve center of the car circuit, and its performance directly affects the normal operation of the vehicle. However, some owners and maintenance personnel do not understand or pay attention to the use and maintenance of the battery, resulting in early damage to the battery and even damage to other electrical equipment.
