Do not overcharge the car battery when charging

It is normal for the car battery to lose power, but does everyone know how to charge the battery correctly? Today, the high-power emergency starter Xiaobian leads everyone to look at the battery charging precautions and the correct charging method. . The specific gravity of electrolyte drops below 1.2; in winter discharge exceeds 25%; summer discharge exceeds 50%; light is dim; when charging is weak, it should be charged. Some owners believe that fast charging can save time and it only takes 3-5 hours. Actually, fast charging just quickly activates the surface of the battery. In fact, the inside of the battery is not fully charged.mobile power plant

In addition to fast charging, there is a slow charging, charging time is 10-15 hours, those who have a deep battery loss must be slow charging, otherwise the charging time is not enough, the charge is insufficient, will directly affect the driving performance of the car. Although charging is a fairly simple operation, there are some considerations:

1. Wear protective clothing when charging lead-acid batteries.

2. When charging, there should be no spark near the battery and smoking is prohibited.

3. When charging one or more batteries in parallel, the charger voltage should not exceed 16V.

Accurate battery charging method

There are more and more electric devices on automobiles today. When the vehicle owners use these electric devices, they should try not to overload the batteries. Overloading the battery will reduce the life of the battery. It is important to have a correct battery charging method.

1. First, connect the positive pole of the battery to the positive pole of the power supply, and the negative pole of the battery to the negative pole of the power supply

2, the initial charge of two phases: first with the initial charge current to the electrolyte discharge bubble, single-cell voltage rose to 2.3 ~ 2.4V so far. Then, the current is reduced to 1/2 of the initial charge current, and the charge is continued to the electrolyte to release violent bubbles, which is stable for 3 hours than the continuous voltage. All charging time is about 45~65h.

3, the charging process should always measure the electrolyte temperature by the current halved, stop charging or cooling method, the temperature is controlled at 35 ~ 40 °C, the initial charge is completed, if the electrolyte specific gravity is not specified, the application of distilled water or specific gravity of 1.4 The electrolyte is adjusted. After adjustment, charge it for 2 hours until the specific gravity meets the regulations.
