Electronic Battery Capacity Tester Digital LCD Display High Power Battery Internal Resistance Test Meter Supporting Multiple Battery Measurements

Features:LCD Display: High-power battery tester with LCD digital display, voltage, current, time, capacity, energy, and other parameters are displayed intuitively, more accurate testing.Battery Capacity Internal Resistance Test: Support a variety of battery measurements, it has newly added battery capacity and internal resistance test function in the battery test. Voltage and current channels are separated, with high testing accuracy.Parameter Setting: Powered by 19V-20VDC, 3.5A or above powersupply. Voltage setting ranges from 0.00-30.00V, stepper in charging mode of 0.01V, the maximum voltage of 18V. Discharge current setting ranges from 0.10-20.00A, stepper of 0.01A, power overrun auto adjust the current. Charging current ranges from 0.10-5.00A, stepper of 0.01A (maximum current depends on powersupply current).Manual Mode: Constant Current Discharge: Discharge current remains constant, recommended for battery capacity testing. Constant Power Discharge: Discharge power remains constant, recommended for simulating constant power devices. Constant Voltage Charging: Charging voltage remains constant, recommended for battery and leadacid battery testing.Auto Mode: The tester supports automatic cycle testing of charging and discharging, recommended for capacity testing.Computers Connection: The tester can be connected to computers via the specified USB-TTL cable for more functions such as graphical calibration, and firmware upgrade.
