- 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 c ircuit.
- 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 c ontact 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, po)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 instruction provided by the manufacturer
strictly.
- Do not attempt to disassemble the battery pack arbitrarily.
- You have to pay attention to verify the capacity and the voltage of the Lithium battery pack. It may be composed of parallel and
series connection mixed. In parallel link the capacity of the battery pack is multiplied by the number of cells but the voltage remains
same. That kind of voltage imbalance causes a
fire or explosion during charge process. We recommend you compose the Lithium
battery pack in series only.
