Electric Battery System Tester,Electric Battery System Tester Multifunctional Battery Internal Resistance Voltage Discharge Current Battery Power Lifesapn Test Meter Digital Display with Voice

About this item 【Kelvin Test Operation】: We give the battery a test signal of a fixed frequency and current (small current), then the voltage is sampled, and after a series of processing such as rectification and filtering, The internal resistance of the battery can be calculated, and almost all batteries can be measured. Low frequency small current, no damage to the battery Suitable for most batteries in the market. 【Digital Display】: The screen is clear and simple, it displays English directly, which is easy to understand and use more convenient. 【Multiple Battery Data Measurement】: It can detect various battery data, including internal resistance, voltage, discharge current, battery power, battery lifesapn, versatile and practical to use. 【Intelligent Voice Broadcasting】: Equipped with intelligent voice broadcasting function, the measurement is automatically broadcast by voice, more intelligent to use. 【Multiple Protections】: Enhanced internal input multiple protections function to prevents polarity reversal and high voltage connection. Added poor contact and other protective measures for testing chuck, making it safer, more convenient, and more accurate.
