Operation modes
Charge Mode: The rechargeable battery is charged up to its maximum capacity. Accumulated charging capacity is displayed at mAH display mode. For Ni-MH or Ni-Cd batteries, after charging mode is completed, a trickle charge current (around 10mA) will be applied. For Li-ion battery, once charge mode is completed, no trickle charge current will be applied. When Li-ion battery voltage is dropped less than 4.0v, then charging will be activated until battery voltage reaches 4.20v.
Discharge Mode: It is used to reduce the memory effect. The rechargeable battery is discharged to a preset battery voltage (0.9v for Ni-Cd & Ni-Mh, 2.8v for Li-ion batteries). Once discharge is finished, total accumulated discharging capacity is displayed at mAH display mode, showing how much energy is discharged from the battery, which is always referring to the accumulated discharging capacity. Trickle charge current will be applied after discharge cycle is finished, preventing the batteries from discharging any further.
Refresh Mode: The rechargeable battery is charged and discharged repeatedly to optimize to its maximum capacity. Old rechargeable batteries or rechargeable batteries that have not been used for a long period of time can be restored to their rated capacity. Depends on the selected charge current and battery impedance, it can take tens hours or even days time before complete. Refresh mode will make 3 complete discharge-charge working cycles before complete. After charge cycle is complete, the total charged capacity will be displayed in mAH display mode even it is at discharging stage of that cycle.
Test mode: Checks the present capacity of a rechargeable battery. The maximum capacity is determined by discharging the rechargeable battery after it was fully charged. If the maximum capacity is much lower than the rated capacity then it may reach the end of its lifetime.
Quick Test
Quick Test mode: The charger will analyze the dynamic internal battery resistance by applying a load and the current reading is referred to the voltage drop detected on the battery. Within 10s, the tested battery resistance will be displayed in the unit of milliohm.
