12v Battery Maintenance Method
- Jun 22, 2017 -

12v battery the correct use and maintenance of the following seven points:

1, check the 12v battery in the bracket on the fixed bolts are tightened, 12V Standard Battery the installation is not reliable due to driving vibration caused by damage to the shell. Also do not put metal objects on the 12v battery to prevent short circuit.

2, often check the pole and the connection is reliable connection. In order to prevent the oxidation of the terminal can apply Vaseline and other protective agent.

3, can not use direct ignition (short circuit test) method to check the 12v battery power This will cause damage to the 12v battery.

4, ordinary lead acid 12v battery should pay attention to regularly add distilled water. Dry charge 12v battery is best charged before use. As for the water-free maintenance-free 12v battery is not impossible to maintain the appropriate view if necessary to add distilled water to help extend the service life.

5,12v battery cover on the pores should be smooth. 12v battery in the charge will produce a lot of bubbles if the air hole is blocked so that the gas can not escape when the pressure increases to a certain extent will cause 12v battery shell burst.

6, in the 12v battery pole and cover the surrounding often have yellow-white paste, this is because the sulfuric acid corrosion of the column, line card, 12V Standard Battery fixed frame caused by. The resistance of these substances is very large, to be cleared in time.

7, when the need to use two 12v battery in series when using 12v battery capacity is best equal. Otherwise it will affect the 12v battery life.

12v battery is the car's power, mainly for the start to the car starter and power supply equipment, are starting 12v battery. At present, the car is basically used in lead acid 12v battery, 12V Standard Battery that is, using dilute sulfuric acid as the electrolyte, the electrode to participate in the electrochemical reaction of the active material for lead dioxide and lead.

In order to meet the needs of start-up and electrical equipment, the replacement of the new 12v battery, the new 12v battery capacity and rating must not be lower than the original 12v battery, and the replacement of 12v battery size must also be appropriate to install. 12v battery on the market today, a lot of brand, concerned about xsjiaoliu, more full car knowledge had known. Mainly Walter VARTA (formerly Delphi), ACDELCO, Panasonic (Panasonic), sailing, uniform, GS, original imported Korean rocket, 12V Standard Battery soup shallow and so on. The manufacturers of 12v batteries also have different labels.

Automotive lead 12v battery models are in accordance with certain standards to name, in the domestic market, the use of 12v battery models are mainly in accordance with national standards and Japanese standards, the German standard and the US standard named.

National standard 12v battery

To model 6-QAW-54a 12v battery as an example, as follows:

1. 6 that consists of six single cell battery, each single cell battery voltage is 2V, that is, the rated voltage of 12V;

Q for the car with 12v battery, M for the car with 12v battery, J for the ship with 12v battery, HK for the aviation with 12v battery, D for the electric car with 12v battery, F for the valve Control 12v battery;

3. A and W that 12v battery type, A said dry charge type 12v battery, W said maintenance-free 12v battery, if not marked ordinary 12v battery;

4. 54 that 12v battery rated capacity of 54Ah (fully charged 12v battery, at room temperature to 20h rate discharge current discharge 20h12v battery output power);

5. The subscript a indicates the first improvement of the original product, 12V Standard Battery and the name is followed by the second sign, followed by the second improvement.

Note: ① model plus D said low temperature start performance, such as 6-QA-110D.

    ② After adding the model HD said high vibration type.

    ③ after the model said DF low-temperature anti-installed, such as 6-QA-165DF.
