In the production process of lead-acid batteries, the most important link is the factory parameter detection of batteries, including battery internal resistance, open circuit voltage and capacity, etc. Batteries are divided into different grades according to different measured parameters, and unqualified products are identified.

[0003] Among them, the open circuit voltage of the lead-acid battery is the main basis for grouping; during the production process, the batteries with basically the same open circuit voltage of the lead-acid battery are grouped to ensure the consistency of the entire group of lead-acid batteries, but most of them are currently grouped manually, and the retesting is done manually; when measuring the open circuit voltage of the battery, a multimeter is generally used, which not only requires holding the multimeter, but also requires operating the detection column on the multimeter, and recording data, which is inconvenient to operate and has low efficiency; due to the high labor intensity of the operation and possible operating errors, the contact between the detection column and the battery pole is not thorough enough, resulting in detection errors; therefore, there are problems such as low detection efficiency and low detection accuracy caused by the difference in the degree of contact with the pole during detection, which in turn leads to the outflow of unqualified batteries, reducing product quality and market reputation. In view of the above problems of inconvenient operation, low efficiency and low detection accuracy, the utility model designs a voltage detection mechanism for lead-acid batteries.
