what is the best car battery tester

S32-512-3A Energy-Saving Regenerative Formation Cabinet Equipment Function Description  The equipment can accurately measure lithium-ion batteries’ parameters such as voltage and capacity. For both charge and discharge, it is shock-free and stable for each battery due to having independent constant current and constant voltage sources, providing accurate and reliable test data. Batteries can be quickly graded automatically based upon the testing results after the testing process. The equipment is capable of both computer control and keyboard operation. Its powerful software functions can monitor real-time battery status, have many protection functions, and can save data and real-time curves. The equipment design is modular, making maintenance easy, and greatly improves the efficiency and accuracy of the battery testing and grading process.      Product Core Advantages High Measurement Accuracy: The independent constant current and constant voltage source coupled with a high-precisi…
