Do not connect more than one battery pack to the charge lead at any one time.
Do not attempt to charge or discharge the following types of battery.
Battery pack, which consists of different types of cell (including different
manufacturers).
-Battery, which is already fully charged or just slightly discharged.
-Non-rechargeable batteries(Explosion hazard).
-Batteries that require a different charge technique from NiCd, NiMH, Lilo,
LiPo, LiFe or Pb.
-Faulty or damaged battery.
-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 of checking the following point before charge operation.
-Did you select the appropriate program, which are suitable for the type of
battery?
-Did you set up adequate current for charging or discharging?
-Lithium battery pack can be composed with parallel and series circuits
mixed. You have to check the composition of the battery pack carefully
before charging.
-Are all connections firm and safe, or is there an intermittent contact at any
point in the circuit?
Charging
A specific quantity of electrical energy is fed into the battery during charge
process. The charge quantity is calculated by multiplying charge current by
charge time. The maximum permissible charge current varies according to
the battery type or its performance, and can be found in the information
provided by the battery manufacturer. It is only allowed to charge batteries
at rates higher than the standard charge current if they are expressly stated
to be capable of quick-charge.
-Connect the battery to charge to output terminal of the charger using
suitable charge lead. They are red, positive(+)and black, negative(-).Since
the charger cannot detect the difference between the internal resistance of
the battery pack, cable resistance and connector transfer resistance, the
first requirement if the charger to work properly is that the charge lead
should be of adequate conductor cross-section. And also high-quality
connectors (normally gold-contact type) must be fitted to both ends.
-Refer to the information provided by the battery manufacturer regarding
charging methods, and verify the recommended charge current and charge
time.Especially for Lithium batteries, you have to follow the charge instruc-
tion provided by the manufacturer strictly.
