Operating software
The operating program in this charger is executed with mutual links and communications
with every component to prevent any possible error, so it introduces the maximum safety.
Especially, the charging algorithm is so multifarious that you can select the best program
to suit your requirement. And E6D has a large LCD for showing various information
including charge/discharge graphs during the process.
Dual input power
E6D employs the circuit that can be operated at AC(Alternating Current) or DC( Direct
Current) input power. For AC input, the charger contains a AC-DC switching power
supplier inside, which has maximum output power of 50 watts for charging. But in DC
input, the charger's maximum output power of 90W. The charger can charge up to 15 cells
of NiCd/NiMH and 6 series of Lithium batteries. There may be the limit of feeding current
to a higher voltage of battery by chargers wattage.
Maximum safety
Delta-peak sensitivity: The automatic charge termination program works on the principle of
the Delta-peak voltage detection.(NiCd/NiMH)
Auto-charge current limit: When charging NiCd or NiMH at “AUTO” current mode, you can
set the upper limit of charge current to avoid from feeding high current to the battery. This
is very useful when charging the low impedance and small capacity NiMH battery in
“AUTO” model.
Capacity limit: The charging capacity always calculated by multiple of the charging current
and time. If the charging capacity exceeds the limit the process will be terminated
automatically when you set the maximum value.
Temperature limit: The temperature of the battery on charging or discharging will be raised
by its internal chemical reaction. If you set the limit of temperature the process will be
expired forcibly when the limit has been reached.
Processing time limit: You can also restrain the maximum processing time to prevent any
possible defect.
Cyclic charging /discharging for NiMH/NiCd battery
Perform 1 to 10 cycles of charge ＞discharge or discharge＞ charge continually for battery
refreshing and balancing.

There batteries need to adopt different
charge technique which is termed constant
current(CC) and constant voltage(CV)
method. As the process starts, the CC
phase will be committed first, in which the
charging current is maintained at a constant
level until the battery reaches their final
charge voltage. And then, the CV phase will
be initiated, in which the voltage is
maintained at a constant level. At this point
the battery already has been charged
about 80-90% full. The charging current
will start to decrease until it reached its
1/10 of starting amount. When the
charging current reached 1/10 of initial
amount, the charger will stop the charging
process. The battery is virtually fully
charged at this point.

- End current: Set the final charging current at termination. The end current should be
less than the initial charge current. (Auto, 60-500mA)
Auto : The process will be terminated when the charging current go to 1/10 of its initial
value. Otherwise the charge current will be decreased until the designated value has been
reached.
- Chk time: E6D recognizes the cell-count of Lithium battery automatically. But the battery
which has been discharged deeply can be perceived the cell-count incorrectly. The charger
will work on the cell-count anyway during the check time. But if the charger finds the wrong
cell-count at the end of check time, the process will be terminated with an error message.
Normally, 10 minutes are enough to perceive the cell-count correctly. For the battery of
larger capacity, you may extend the time term. (5-250min)
- CV Hold: The charger will try to keep the final voltage of battery after finishing charge
process, if this sets 'ON'. When you let the battery remain connecting to charger, the
charger will keep working on charging with very small feeding current and the voltage
never drop below the final charge voltage. The balance job also will be kept on, if the
balance plug is connected. How long the battery remains in connection to charger, the job
will last until the battery is pulled out from charge leads (ON/OFF)
Safety programs for all types of battery
- Safety temp: This is a feature using temperature probe contacting the surface of battery,
which can monitor the temperature of battery. The recommended maximum temperatures
are 45-55C(113-130F) for NiCd, 43-52C (110-125F) for NiMH and 32-35C (90-95F) for
Lithium. Once the battery reaches this temperature during the process, the program will be
terminated forcibly to protect the battery. If the battery reaches the temperature during
discharge, the discharge process the will temporarily pause to allow the battery to cool
down to a safe temperature. Then ,discharge process will automatically resume when the
battery's temperature drops about 4℃ below the battery to reach during charge or
discharge process. (20-80C)
- Safety timer: When you start a charge process , the integral safety timer automatic
starts counting. This is programmed to prevent over-charging or deep-discharging the
battery, when the charger or battery is proved to be fault, or the termination circuit cannot
detect the end of process. The value for the safety timer should be generous enough to
allow the full-charging.(10-1380min)
- Max capacity: You can define the maximum capacity which can be charged or
discharged by the form of a percentage of battery capacity set in the top of display. If full-
charge has not been detected for any reason, the charger limits the quantity of feeding
energy by the value and terminates the process as on the value is reached. This is safety
feature programmed to protect the battery from over-charging or deep-discharging
condition.(50-120%)

After setting up all parameter, press and hold 'ENTER' button for more than three seconds
to go for the next step. The display will show you the choice of options which are charge or
discharge.
Press 'UP' or 'DOWN' button to select 'Charge' or 'Discharge', and press 'INC' or 'DEC'
button to choose a sub-program to be performed. To start the process, locate the cursor at
the sub-program to be performed then press and hold 'ENTER' button for three seconds.
- Charge 'Balance': This is for balancing the voltages of each individual cell of battery
pack to be charged. To do this, the battery pack being charged should have the individual
cell connector. And connect it to the individual port at the right side of charger with a
suitable connection adaptor that fits with your battery. And also, you should to connect the
battery ordinary charging mode. The internal processor of the charger will monitor the
voltages of each cell of the battery pack and controls the charging current that is feeding to
each cell to normalize the voltage.
- Charge 'Storage': This is for Lithium battery not to be used for long time. The program
will determine to charge or discharge the battery to a certain voltage depending on the
voltage of the battery at its initial stage. The final voltages are different from type of
batteries, 3.6V for Lilo. 3.7V for LiPo and 3.3V for LiFe per cell. If the voltage of battery at
its initial stage is over the voltage level to storage, the program will start to discharge.
- Charge 'Fast': The charging current is getting smaller as the process goes to the near
end term of Lithium battery charging. To finish charging process earlier, this program
eliminate certain term of CV process. Actually, the charging current will goes to 1/5 from
the initial value to end the process while the normal charging goes to 1/10 during CV term.
The charging capacity may be a bit smaller than normal charging but the charging time will
be reduced.
- Discharge ' Normal': The charger will keep on discharging with the discharge current
continuously until the discharge voltage has been reached.
- Discharger 'CV-mode': The discharging current will be decreased gradually until the end
current which has been set up at 'End current' has been reached, when the voltage has
been dropped to the final discharge voltage. For maximum discharge , use this mode.

It is very important to know the exact type of battery to be charged, nominal voltage and
capacity. Not to know these facts is the reason why batteries are damaged and improperly cared for.
Read the batter's label and instruction sheet carefully, or consult the battery supplier to get those facts.

These programs are for charging, discharging or cycle NiMH (Nickel-Metal-Hydride) or
NiCd (Nickel-Cadmium)battery commonly used for R/C model applications. The charge
current varies according to the battery capacity and performance. The type of battery
which is either NiMH or NiCd must be correct for the battery being charged.
Selct 'CHG/DCHG' program at main menu by pressing 'UP' or 'DOWN' button, and press '
ENTER' to go for the program.
You can choose the type of battery to be charged or discharged at the first section. Select
NiCd or NiMH according to your battery. And then , select the data number which will

- Delta-peak (Delta-peak voltage sensitivity): Set the Delta-peak voltage sensitivity at
termination. (Disable, Delicate, Default, 5-20mV/cell)
Disable: The charger would not detect Delta-peak voltage for termination. To terminate
charging process, the charger will check the parameters set up at other safety parameters
like max. capacity, safety timer or safety temperature. If anyone has been reached at its
limit, the charging process will be terminated.(for NiMH only)
Delicate: The charger will detect a very small variation at delta-peak voltage. Some NiMH
batteries which shows small voltage-drop at peak need to be use this option.
Default: If you do not know much about this function, or for ordinary batteries, select this
mode. 15mV/cell for NiCd or 10mV/cell for NiMH will be used.
- End current: Set the final charging current at termination. The end current should be less
than the initial charge current. (Auto, 60-500mA)
Auto: The process will be terminated when the charging current go to 1/10 of its initial
value. Otherwise ,the charge current will be decreased until the designated value has been
reached.
- Trickle curr: Activate or deactivate the trickle charge after the termination of
process.(Off, 50-300mA)
- Peak delay: This restrains the delta-peak voltage detection until the time has reached.
This prevents a premature cut-off from the battery of high internal resistance. The default
value is one minute.(1-15 minutes)
- No. cycles: The number of cycles in the process. (1-10 times)
- Waste time: To avoid the battery from rising temperature caused by the internal chemical
reactions. There should be a brief cool-off time between cycles.(0-60 minutes)
The most distinctive point on the voltage
curve of a charging battery in response to
a constant current is the voltage peak
that occurs as the cell approaches full
charge. The voltage will slightly drops
after its maximum point. The charger
works with proven 'Delta-peak voltage
termination' to terminate charge process
for NiCd and NiMH batteries. The actual
termination point depends on the
charging characteristics of the particular
battery. Please refer the specification
which is provided by the battery
manufacturer.

seconds to go for the next step. The display will show you the choice of options which are
charge, discharge and cycle.
Press 'UP' or 'DOWN' button to select 'Charge' ,'Discharge' or 'CYCLE', then chose a sub-
program to be performed using 'INC' or 'DEC' button. To start the process, locate the cursor at
the sub-program to be performed then press and hold 'START/ENTER' button for three seconds.
- Charge mode: Set the charge mode which the charger will work with.
Normal: The charger will work with the parameters which were set at the screen. The
feeding current will be zero at every 90 seconds to have 6 seconds of waster-time for
higher charging efficiency.
Auto: The optimum charge current will be set by the charger automatically. The charge
current set at 'Chg current' will be upper limit of charge current.
Linear: The charging current will be fed continuously without hesitating. The battery is
charged with pure 'Direct-Current'.

Normal: The charger will finish discharging at the time when the voltage drops to the final
voltage set at 'Dchg voltage'.
Auto: The charger will discharge the battery until the voltage drops to 0.90V per cell.
CV-mode: When the voltage has been dropped to the final discharge voltage, the discharger
job will continue until the end current which has been set at 'End current' has been reached
with decreasing discharge current gradually. For maximum discharge, use this mode.
- Cycle mode: You can use this function for balancing , refreshing and break-in the
battery. All of charging and discharging parameters will be adopted from the values of
'CHARGE' and 'DISCHARGE' programs. Select the sequence of performing program.
CHG>DCHG: The charger starts with charging process, then the battery will be discharged.
DCHG>CHG: It starts with discharging process, then the battery will be charged.
Cautions for NiMH batteries
-Do not allow NiMH batteries to over-heat. Using the battery cooler will prevent over-heating at
charge and discharge.
-Small size batteries like 'AAA','AA' and 'A' can safely be full charged at currents up to 1.0C.Higher
charge current can easily over-heat batteries and thus damage batteries.
-NiMH batteries have higher self-discharge rate compare to NiCd, so it is necessary to recharge the
battery immediately prior to use.
-Store NiMH batteries with some voltages remaining.

This is programmed for charging Pb(lead-acid) battery with nominal voltage from 2 to 22V
Pb batteries are totally different from NiCd or NiMH batteries, but very similar with Lithium
batteries. They can only deliver relatively lower current compare to their capacity , and
similar restrictions apply to charge. So the optimal charge current will be 1/10 of the
capacity, and Pb batteries must not be charged rapidly. Always follow the instruction which
was supplied by the battery manufacturer.
Select 'CHG/DCHG' program at main menu by pressing 'UP' or 'DOWN' button, and press'

successfully before, you can just start the process after loading the data number. All set up
data will be stored at charger's memory automatically after setting them all.
Input the cell-count and capacity of the battery will be charged at the top line of menu. The
cell-count and capacity need to be matched with the battery.
Use 'UP' or 'DOWN' button to scroll up and down the menu, and change the value by
using 'INC' or 'DEC' button. To start the process, press and hold 'ENTER' button for more
than 3 seconds regardless of cursor position.
- Chg current: Set the charge current.(0.1-6.0A)
