Be very careful to choose the correct voltage for different types of battery otherwise you may cause damage
to the batteries. Incorrect settings could cause the cells to fire or explode.
WARNING AND SAFETY NOTES
During charge process, a specific quantity of electrical energy is fed into the battery. The charge quantity is
calculated by multiplying charge current by charge time. The maximum permissible charge current varies
depending on the battery type or its performance, and can be found in the information by the battery
manufacturer. Only batteries that are expressly stated to be capable of quick-charge are allowed to be
charged at rates higher than the standard charge current.
Charging
Did you select the appropriate program suitable for the type of battery you are charging?
Did you set up adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired in parallel and
in series, i.e. a 2 cell pack can be 3.7V (in parallel) or 7.4V (in series).
Have you checked that all connections are firm and secure?
Make sure there are no intermittent contacts at any point in the circuit.
Please bear in mind the following points before commencing charging:
A battery pack which consists of different types of cells (including different manufacturers)
A battery that is already fully charged or just slightly discharged.
Non-rechargeable batteries (Explosion hazard).
Batteries that are require a different charge technique from NiCd, NiMh, LiPo or Gel cell
(Pb, Lead acid).
A faulty or damaged battery.
A battery fitted with an integral charge circuit or a protection circuit.
Batteries installed in a device or which are electrically linked to other components.
Batteries that are not expressly stated by the manufacturer to be suitable for the currents
the charger delivers during the charge process.
Never attempt to charge or discharge the following types of batteries.

WARNING AND SAFETY NOTES
Connect the battery to the terminal of the charger: red is positive and black is negative. Due to the
difference between resistance of cable and connector, the charger can not detect resistance of the battery
pack, the essential requirement for the charger to work properly is that the charge lead should be of
adequate conductor cross-section, and high quality connectors which are normally gold-plated should be
fitted to both ends.
Always refer to the manual by the battery manufacturer pertaining to charging methods, recommended
charging current and charging time. Especially, the Lithium battery should be charged according the
charging instruction provided by the manufacturer strictly.
Attention should be paid to the connection of Lithium battery especially.
Do not attempt to disassemble the battery pack arbitrarily.
Please get highlighted that Lithium battery packs can be wired in parallel and in series. In the parallel
connection, the battery capacity is calculated by multiplying single battery capacity by the number of cells
with total voltage stay the same. The voltage imbalance may cause fire or explosion. Lithium battery is
recommended to charge in series.
WARNING AND SAFETY NOTES
The main purpose of discharging is to clean residual capacity of the battery, or to reduce the
battery voltage to a defined level. The same attention should be paid to the discharging process as
charging. The final discharge voltage should be set up correctly to avoid deep-discharging. Lithium
battery can not be discharged to lower than the minimum voltage, or it will cause a rapid loss of
capacity or a total failure. Generally, Lithium battery doesn’t need to be discharged. Please pay
attention to the minimum voltage of Lithium battery to protect the battery.
Some rechargeable batteries have a memory effect. If they are partly used and recharged before
the whole charge is accomplished, they remember this and will only use that part of their capacity
next time. This is a memory effect. It is said that NiCd and NiMH batteries are suffering from memory
effect. NiCd has more memory effect than NiMH.
Lithium batteries are recommended to be discharged partially rather than fully discharged. Frequent
full discharging should be avoided if possible. Instead, charge the battery more often or use a
battery of larger capacity. Full capacity cannot be reached until it has been subjected to 10 or more
charge cycles. The cyclic process of charge and discharge will optimize the capacity of battery pack.

The screen displays the nominal voltage of Lithium battery. There are three kinds of
Lithium battery: LiFe(3.3V), Lilo(3.6V) or LiPo(3.7V). This is very important so you
have to check the battery carefully and set it up correctly. If it is different from
correct value the battery may be exploded during charge process.
Ultimate 400W recognize the cell count of Lithium battery automatically at the
beginning of charge or discharge process to avoid from erroneous setting by user.
But deeply discharged battery can be perceived incorrectly. To prevent the error,
you can set the time term to verify the cell count by the processor. Normally, 10
minutes are enough to perceive the cell count correctly. For the battery of larger
capacity, you may extend the time term. But if you set the time term too long for the
battery of smaller capacity, the charge or discharge process can be finished within
the time term with the erroneous cell count. This may cause the fatal result. If the
processor recognizes the cell count incorrectly at the beginning of charge or
discharge process, you may extend the time. Otherwise, you had better use with
the default value.

Termination of NiMH and NiCd battery, the effective value ranges from 5 to 20mV
per cell. If the trigger voltage is set higher, there is a danger of over charging the
battery; if it is set lower, there is a possibility of premature termi nation. Please
refer the technical specification of the battery. (NiCd default: 12mV, NiMH default:
7mV)
An optional feature using temperature probe contacting the surface of battery,
the temperature cut-off can be on or off. If it is on, set the maximum temperature
at which the charger should allow battery to reach during charge. Once a battery
reaches this temperature during charge, the process will be terminated to protect
the battery.
The battery is on the cyclic process of charge and discharge can often become
warm after charge or discharge period. The program can insert a time delay to
occur after each charge and discharge process to allow the battery adequate
time to cool down before being subjected to the next process. The value ranges
from 1 to 60 minutes.
You can set the trickle charge mode on or off. If it is on, the charger will
automatically supply the trickle charge current to achieve the full charge without
overheating the battery after fast charge has been terminated.

When you start a charge process, the integral safety timer automatically starts
running at the same time. This is programmed to prevent overcharge the battery
if it proves to be faulty, or if the termination circuit cannot detect the battery full.
The value for the safety timer should be generous enough to allow a full charge
of the battery.
This program sets the maximum charge capacity that will be supplied to the
battery during charge. If the delta-peak voltage is not detected nor the safety
timer expired by any reason, this feature will automatically stop the process at
the selected capacity value.
The beep sounds at every time pressing the buttons to confirm your action. The
beep or melody sounded at various times during operation to alert different mode
changes. These audible sounds can be turned on or off.
This program monitors the voltage of input battery. If the voltage drops below the
value you set the operation forcibly terminated to protect the input battery.
You can adjust the brightness of LCD screen at the charger.
LITHIUM BATTERY (LILON/LIPO/LIFE) PROGRAM
Lithium battery (LiIon/LiPo/LiFe) program
These programs are only suitable for charging and discharging Lithium batteries with a nominal voltage of
3.3V, 3.6V and 3.7V per cell. These batteries need to adopt different charge technique that is termed
constant current (CC) and a constant voltage (CV) method. The charge current varies according to the
battery capacity and performance.

The Lithium polymer battery is charged at a constant
current until it reaches the final charge voltage of 4.2 V
per cell (B). After this point the voltage is kept at a
constant level, and the residual charge takes the form
of a declining current curve (C) until the cut-off point
(D) is reached. Charge current = C/10. At this point
the battery can be disconnected from the charger, and
is ready for use.
The final voltage of charge process is also very important; it should be precisely matched with the charged
voltage of the battery. They are 4.2V for LiPo, 4.1V for Lilo, and 3.6V for LiFe. The charge current and
nominal voltage as for cell count set on the charge program must always be correct for the battery to be
charged.
When you are willing to alter the parameter value in the program, press start/enter key to make it blink then
change the value with Inc> or <Dec key. The value will be stored by pressing start/enter key once.

（lead-acid）battery is completely different from NiCd/NiMH battery. These batteries can only deliver
current lower in comparison to their capacity. The same restriction applies to the charging process.
Consequently, the optimum charge current can only be 1/10 of the capacity. Pb battery can not be used for
fast-charging, please follow the instructions provided by the battery manufacturer.Due to the chemistry
characteristic of Pb battery, the cut off point may be difficult to detect sometimes. We recommend user to
use CAPACITY CUT OFF feature to protect the battery. You can press START/ENTER key to make it blink
and alter the value of parameters using INC or DEC key, press START/ENTER key to store the value.
