Features:
<br />The battery tester is for monitoring parameters(voltage, current, capacity, charge and discharge resistance) status when battery is charged or discharged.
<br />Testing Range: load current 0.0~10.0A, load resistance 0 999 Ohm, battery voltage 2.8-29.9V, battery capacity is shown by the grid(total five) on the display.
<br />It need a calibration before testing current and voltage the battery cut-off voltage and full-scale voltage can be set within 2.8V ~ 29.9V.
<br />The checker has to connect a discharge load(not included), with blue backlight, and it can be turned on/off by button, default off.
<br />Very accurate to test phone, mobile power, 18350/18650/26650 batteries and other Li-ion batteries, can avoid ruining your devices by bad Li-ion battery.
