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 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 battery manufacturer about 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

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.
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.

NiMH/NiCd Charge Mode:
BEFORE YOU BEGIN CHARGING YOUR BATTERY, MAKE SURE YOU HAVE
READ AND UNDERSTOOD ALL OF THE WARNINGS AND SAFETY
INFORMATION CONTAINED ON PAGES 05-07.
After selecting the correct battery type, if the screen does not read “CHARGE”,
use the DEC or INC buttons to change it to the “CHARGE” mode.
NiMH/NiCd Auto Charge Mode:
In this mode, the charger automatically detects the connected NiMH or NiCD battery
and determines the proper full charge and cut-off thresholds. Setting the upper charge
current limit for safe levels based on your battery specifications will ensure safe
charging of your specific battery. If you are unsure of the maximum allowable charge
rates, set the charger to a maximum of 1C (battery mAh/1000, e.g. 3200mAh = 3.2A).
BEFORE YOU BEGIN CHARGING YOUR BATTERY, MAKE SURE YOU
ARE CHARGING NIMH/NICD BATTERIES. CHARGING LIPO BATTERY
UNDER NIMH/ NICD BATTERY PROGRAM WILL CAUSE FIRE.
