Operation Modes and Display
5.1 Charger Operation Modes:
Charge Mode: The rechargeable battery is charged up to its
maximum capacity. Accumulated charging capacity is displayed
at mAH display mode.
Discharge Mode: It is used to reduce the memory effect. The
rechargeable battery is discharged to a preset battery voltage
(0.9v). 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. No trickle charge current will be applied after
discharge cycle is finished.
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
discharge cycle is complete, the total discharged capacity will
be displayed in mAH display mode. When its current working
cycle is in charging state, the mAH display is always referring to
last discharging cycle for its charged capacity..
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.
Impedance Test mode: The charger will analyze the dynamic
internal battery resistance by applying a load current and this
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. For good quality batteries, the
internal resistance is very low: in the range of 20 ~ 80 milliohms.
If battery internal resistance is over 500milliohms, then these
batteries are not good for supplying power to high current loads,
such as digital camera etc. But they can still be used for low
energy loads, such as clock, remote controllers etc. Always
use batteries with close internal resistance range when they
are used in serial to achieve maximum battery life. Alkaline and
any other 1.5v batteries can be tested on this charger as well. If
a completely empty battery is to be tested, it is not possible to
give any correct reading. Please be noted that since the
internal battery resistance can be very small, and contact
resistance can be a major influence factor, thus same battery
tested in different slot or even at the same slot with different
contact condition, the reading can be varied for 10% to 20%.
This is normal.
When a high impedance battery( e.g. Over 2500milli ohm) is
loaded onto the charger, due to its high internal impedance,
real displayed charging current can be much less than your
pre-selected charging current. When this happened, it doesn’t
mean the charger is defective. Eventually it needs longer
charging time until fully charged.
5.2 USB OUTPUT MODE
Press “CURRENT” button to turn on/off USB output. When USB
output is at ON state, press “CURRENT” button to toggle display
between current and AH.
5.3 Display
Charge/Discharge Current: instantaneous current is displayed.
Time Elapsed: The charging/discharging time of the last cycle is
displayed.
Accumulated Capacity: The accumulated battery capacity is
displayed in mAh. For discharge mode, it is referring to the
accumulated energy discharged from that battery. For refresh
mode, previous charging capacity is displayed even when current
working stage is at discharge cycle.
Battery Voltage: The instantaneous battery voltage is displayed.
At IMPEDANCE TEST mode, it shows the internal battery
resistance in mili- ohm(0.001R).
Full: After the rechargeable battery is fully charged in any of the
operation modes, trickle charging will be started automatically.
Trickle charging prevents the rechargeable batteries from being
overcharged and compensates for self-discharging of the batteries
