Electric Battery System Tester Multifunctional Battery Internal Resistance Test Meter with Voice Broadcasting Supporting Multiple Battery Measurements

Features:
【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.
【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.
【Digital Display】: The screen is clear and simple, it displays English directly, which is easy to understand and use more convenient.
【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.
【Recommended Battery Types】: Test multiple car starts aluminic-acid battery, AGM/EFB Starts or stops the battery, car starter battery, EPS aluminic acid battery, battery for electric vehicle, UPS colloidal battery, colloidal battery. (Note :UOS batteries/motorcycle batteries can only measure internal resistance/electricity/voltage, do not support to test battery lifespan.)
【Battery-free】: Don't worry about running out of power. The product is more convenient to use without installing batteries.
【Wide Applications】: Suitable for 12/24V vehicle, gasoline car, motorcycle, electric motorcycle, electric bicycle, etc.
