How to judge the "reference value" of battery internal resistance tester?

If the internal resistance of the battery is higher than 50% or more of the reference value 100%, the battery should be replaced. When the internal resistance is 25% to 43% higher than the reference value, it is recommended to contact the manufacturer. When it is higher than 43%, load test should be carried out. Some people think that all the data (new batteries or batteries with good performance) are concentrated near the reference value, and the data obtained from the later test can reasonably approximate any trend curve. That is to say, the high-capacity battery has a uniform low internal resistance, while the internal resistance of the low-capacity battery will increase proportionally. But the fact is that these people are disappointed, and even the new batteries produced under strict control can not achieve the above characteristics. ? During the user's own test, it will be found that the internal resistance of some large-capacity batteries is very high. Similarly, ordinary batteries with low resistance characteristics cannot be tested for capacity. Unfortunately, in the current state of technology, without the help of load testing, users cannot completely distinguish these irregular batteries by testing impedance, conductance, admittance and resistance. ? If the user is lucky enough to have a large number of battery capacity and corresponding internal resistance data, a set of reference values can be easily established, thus completing the above work of distinguishing these irregular batteries. When the establishment of this reference value has just begun, or there are only a few special types of batteries, some can be selected as reference values from the guessed approximate data. ZY DN？ Battery internal resistance tester is a digital storage multifunctional portable tester, which can quickly and accurately measure battery running state parameters. The instrument can monitor the voltage and internal resistance of the single battery online, store and process the monitoring data, give an alarm to the battery failure, and accurately and effectively judge the excellent condition of the single battery. The instrument can save, query, delete and export test data. The upper computer software processes the imported data, analyzes and displays the data through various charts, and automatically generates the battery test report.
