What testing items are generally included in the laboratory of lead acid battery factory!

Laboratory? I guess it's a testing room or a laboratory.

The testing room generally needs to do the testing of the comprehensive performance of the battery, including capacity testing, safety testing, life testing, etc., you can refer to the battery category you do, refer to the relevant national standards, and have detailed testing items.

The laboratory generally needs to do the testing of the chemical analysis and testing items of the materials used in the battery, as well as the testing and analysis items involved in the battery manufacturing process, such as the free lead of the cured green plate, the lead sulfate, and the lead oxide of the lead powder, etc.

National Power Battery Product Quality Supervision and Inspection Center, in Xiangyang, Hubei.

Hubei Provincial Battery Quality Supervision and Inspection Center is the main body. It has cooperated with Wuhan University of Technology, Hubei University of Arts and Sciences, Xiangyang Da'an Automobile Testing Center, and Hubei Provincial Institute of Electronic Information Products Supervision and Inspection in Xiangyang City to achieve complementary advantages and resource sharing, and strive to build a scientific system of production, learning, inspection and research.

The center has built five laboratories, namely power battery testing laboratory, drive motor and controller testing laboratory, charger and DC DC converter testing laboratory, environmental and safety testing laboratory, and power system comprehensive testing laboratory, covering the inspection capacity of 31 types of products such as electric vehicles, electric ships, electric forklifts, electric motorcycles and other equipment and devices powered by electricity.

The testing of various electrical properties shall be carried out according to the national standard of the corresponding battery.

Conventional tests: C10 (10-hour rate capacity), C20 (20-hour rate capacity), 1C (27-minute rate C(7-minute rate)....

Refer to the national standard. gb/t

It can be measured with a multimeter.

Turn the multimeter to the 20V or 50V range, touch one end with a red pen and touch the other end with a black pen. If the displayed number is positive, or if the pointer swings to the right, then the red pen end is positive and the black pen end is negative.

If the pointer swings to the left, or if the number shows a negative number, the black pen is positive at one end and the red pen is negative at the end.

The equipment to be tested has a large power, and it is better to use a battery when the rated voltage is higher, and the equipment to be tested is small and exquisite, with a small power and low voltage, and the dry battery is reasonable. Adjustable regulated power supply can be used for ordinary testing, which is economical and convenient.

It is best to use a CBTL (Guanghu Hezhou Banghe Test is the CBTL of Lai Sui Nuclear Paiyin), but you can also use a Country Accreditation Body such as a CNAS accredited laboratory, or a Singapore Accredited Laboratory (SAC). It should also be noted that the test report IEC 62133 (2012) will be fully accepted, if IEC 62133:2017 requires a supplementary UN or an UN report issued by a qualified laboratory.
