★About 18650 battery

The minimum discharge stop voltage of 18650 battery is generally: 2.75V. Under normal circumstances, when the voltage drops to 0.875 times the rated voltage (3.24V)

It should be charged, and then continue to use, the voltage will drop rapidly, there may be over-discharge and damage, affecting the life. (Recommended discharge termination

(The voltage is set to 3.5V)

The charging voltage is generally: 4.20V-4.3V/4.35V.

★Measurement time calculation

Assuming that the battery capacity is 2000mAH, the discharge current of this tester is about 500mAH, (2000:500=4), and the measurement time is about 4 hours

about.

Product weight: 110g (including packaging); net weight 74g

Safety Tips: The load resistance will release a high temperature of 60~80℃ during discharge. Keep ventilation during use, avoid close to flammable and explosive materials, and notify you to pay attention to safety and avoid burns.

Working mode (need to connect to 5V power supply)

AUTO-TEST automatic mode (boot default mode)

Start → charge (charge current is less than 0.12A, trigger full charge, stop charging) → discharge (load voltage is less than 2.7V, trigger discharge complete) → charge (charge current less than 0.12A trigger full charge, stop charging) → complete stop

①The capacity and energy values are not recorded during charging, only timing.

②Record the capacity and energy value when discharging, the same is timing.

CHARGE (charging mode)

Start → charge (the charging current is less than 0.12A to trigger full charge and stop charging) → complete stop

①Only record the charging time, not the charging capacity and energy

DISCHARGE (discharge mode)

Start → discharge (load voltage is less than 2.7V, trigger discharge is completed → complete stop)

①Record the discharge capacity, energy and time.
