Battery Testing Suite

Startup Test:Detects the current starting performance of the battery and helps judge the service life of the battery. Shows CUR, MIN, and MAX voltage with anomaly detection.

Charging Test:Quickly diagnoses whether there is a malfunction in the power generation system. Shows Load Voltage, No-load voltage, and Voltage fluctuation. Ideal for diagnosing: car won't start, battery dies after full charge, or rapid battery loss after replacement.

Load Test:Records the voltage fluctuation of automobile on and off load in real time, and can accurately determine the health status of the battery.
