manufacturers)
A battery that is already fully charged or just slightly discharged.
Non-rechargeable batteries (Explosion hazard).
Batteries that 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.
Please bear in mind the following points before commencing 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.
Charging
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.
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.
Never attempt to charge or discharge the following types of batteries.

WARNING AND SAFETY NOTES

Ultimate 200W×2
Discharging
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.
WARNING AND SAFETY NOTES
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 s capacity is calculated by multiplying
single battery capacity by the number of cells with total voltage stay the same. The
voltages imbalance may cause fire or explosion .Lithium battery is recommended to
charge in series.

User set up starting screen.
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 200W×2 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 termination. Please refer the technical
specification of the battery. (NiCd default: 12mV, NiMH default:
7mV)
Ultimate 200W×2 will be operated with the default value of the essential user settings

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.
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.
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.
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.
You can adjust the brightness of LCD screen at the charger.
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.

LITHIUM BATTERY (LIION/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 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.
