WARNING AND SAFETY NOTES

Never attempt to charge or discharge the following types of batteries.

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 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 quick­charge 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 gold­plated 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.

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.

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.

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)

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).

COMMONLY USED TERMS

Commonly used terms

Final charge voltage: the voltage at which the battery's charge limit (capacity limit) is
reached. The charge process switches from a high current to a low maintenance rate
(trickle charge) at this point. From this point on further high current charging would cause
overheating and eventual terminal damage to the pack.

Final discharge voltage: the voltage at which the battery's discharge limit is reached. The
chemical composition of the batteries determines the level of this voltage. Below this
voltage the battery enters the deep discharge zone. Individual cells within the pack may
become reverse in this condition, and this can cause permanent damage.

A, mA: unit of measurement relating to charge or discharge current.1000 mA = 1 A
(A=Ampere,mA=Milliampere)

Ah, mAh: unit of measurement for the capacity of a battery (Amperes x time unit; h = hour).
If a pack is charged for one hour at a current of 2 A, it has been fed 2 Ah of energy. It
receives the same quantity of charge (2 Ah) if it is charged for 4 hours at 0.5 A, or 15
minutes (=1/4 h) at 8 A.

'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers recommend
charge and discharge currents based on the battery 'C' rating. A battery's '1C' current is the
same number as the battery's rated capacity number, but noted in mA or amps. A 600mAh
battery has a 1C current value of 600mA, and a 3C current value of (3 x 600mA) 1800mA or

1.8A. The 1C current value for a 3200mAh battery would be 3200mA (3.2A).

Nominal voltage(V): The nominal voltage of the battery pack can be determined as follows;

-.NiCd or NiMH: multiply the total number of cells in the pack by 1.2. A 8-cell pack will have a
nominal voltage of 9.6 volts (8x1.2).

-.LiPo: multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will
have a nominal voltage of 11.1 volts (3x3.7).

-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in series will have
a nominal voltage of 7.2 volts (2x3.6).

-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiIo wired in series will have
a nominal voltage of 13.2 volts (4x3.3).
If the nominal voltage of the battery is not printed on the battery's label, consult your battery
manufacturer or supplier. Do not guess the rated voltage of battery.

Warranty and service

We guarantee this product to be free of manufacturing and assembly defects for a period
of one year from the time of purchase. The warranty only applies to material or
operational defects, which are present at t he time of purchase. During that period, we will
repair or replace free of service charge for products deemed defective due to those
causes.

You will be required to produce proof of purchase (invoice or receipt). This warranty is not
