Did you select the appropriate program suitable for the type of battery you are charging?
Make sure there are no intermittent contacts at any point in the circuit.
During the charge process, a specific quantity of electrical energy is fed into the battery. The charge capacity 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 provided 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 cannot 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 that high quality connectors which are normally gold-plated should be fitted to both ends.
Always refer to the manual by the battery manufacturer about charging methods, recommended charging current and charging time. Especially, the lithium battery should be charged strictly according to the charging instruction provided by the manufacturer.
Special attention should be paid to the connection of lithium battery.
Do not attempt to disassemble the battery pack arbitrarily.
Be aware that lithium battery packs can be wired in parallel or in series. When the battery is connected in parallel, its capacity is calculated by multiplying the single battery capacity by the number of cells with the total voltage staying the same. Voltage imbalance may cause fire or explosion. Lithium battery is recommended for charging in series.
The charger is not suitable for children under 14 years old. People with behavior disturbance, mental disorder or no experience should use it under the supervision and guidance . Children are forbidden to play with it. They are also NOT allowed to clean and maintain the device without the supervision.
If the power cord is damaged, please return it back to the us, supplier or technicians for replacement for fear of danger.
