Battery Tester, 200 100V Portable Battery Internal Resistance Voltage Tester 3-Digit Display Battery Tester High-Precise True Four-Wire AC Lithium Lead-Acid Lithium Battery Detector

Internal Resistance & Voltage MeasurementThe battery tester can assess internal resistance and voltage simultaneously. This tool employs a four-wire test clamp, which better prevents the influence of contact and wire resistance, enabling more precise readings. Clear & Backlight LCD DisplayThe digital battery tester features a large LCD screen that presents internal resistance, voltage, and battery level of the tested battery for easy reading. Battery level is shown via a bar display, offering clear and accurate status information. Kalman Filter Mathematical AlgorithmThis product uses intelligent control, incorporating a Kalman filter algorithm for efficient operation. It can also test AC resistance of resistors and low-resistance, high-precision resistance. Port Communication & Computer AnalysisThis product is compatible with serial ports. Resistance measurement range is 1~200, and voltage measurement range is 0.0001V~±100V DC. Serial port communication and computer analysis software are included. The serial port must be enabled on the device to communicate with a computer; it is closed by default, with a baud rate of 115200. Light Weight & Energy SavingThis tester features a built-in 1000mAh lithium battery for extended operating time, and can be recharged via USB cable. Its portable size makes it easy to carry, allowing you to bring it wherever needed. Wide ApplicationsThis product is widely applied in battery production, maintenance, testing, scientific research laboratories, and other settings
