Warnings and safety notes

Never leave the charge unsupervised when it is connected to its power supply. If any malfunction is observed immediately terminate the process and refer to the operation manual. Keep away the unit from dust, damp, rain, heat direct sunshine and vibration. Do not drop it. The circuit of the unit is designed to be powered by a 12V DC only. This unit and the battery to charge or discharge should be set up on a head-resistant, non-inflammable and non-conductive surface. Never place them on a car seat, carpet or similar. Keep all the inflammable volatile materials well away from operating area. Be sure to understand the information of the battery to be charged or discharged accurately. If the program is set up incorrectly the battery can severely be damaged. Especially Lithium battery can cause a fire or an explosion by over-charging.
NiCd/NiMH voltage level: 1.2V/cell allowable fast charge current: 1C ~ 2C depends on the performance of cell discharge voltage cut off level: 0.9V/cell(NiCd), 1.0V/cell(NiMH) LiIo voltage level: 3.6V/cell max. charge voltage: 4.1V/cell allowable fast charge current: 1C or less min. discharge voltage cut off level: 3.0V/cell or higher voltage level: 3.7V/cell max. charge voltage: 4.2V/cell allowable fast charge current: 1C or less discharge voltage cut off level: 3.0V/cell or higher voltage level: 3.3V/cell max. charge voltage: 3.6V/cell allowable fast charge current: 4C or less (e.g. A123M1) discharge voltage cut off level: 2.0V/cell or higher

To avoid short-circuits between the charge lead, always connect the charge cable to the unit first and only then to the battery to be charged or discharged. Reverse the sequence when disconnecting. 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, LiIo, 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 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. Discharge The typical purpose of discharge is to determine the residual capacity of the battery, or to lower the voltage of battery to a defined level. When you discharge the battery you also have to pay attention on the process same as charging. To avoid the battery becoming deep-discharged, set the final discharge voltage correctly. Lithium batteries should not be deep-discharged to lower than the minimum voltage, as this leads to a rapid loss of capacity or a total failure. Generally, you do not need to discharge Lithium battery voluntarily. - Some rechargeable batteries are said to have a memory effect. If they are partly used and recharged before the whole charge is drawn out, they 'remember' this and next time will only use that part of their capacity. This is a 'memory effect'. NiCd and NiMH batteries are said to suffer from memory effect. They prefer complete cycles; fully charge then use until empty, do not recharge before storage - allow them to self-discharge during storage. NiMH batteries have less memory effect than NiCd. - The Lithium battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided if possible. Instead, charge the battery more often or use a larger battery. - The brand-new NiCd battery pack is partially useful with its capacity until it has been subjected to 10 or more charge cycles in any case. The cyclic process of charge and discharge will lead to optimize the capacity of battery pack. Those warnings and safety notes are particularly important. Please follow the instructions for a maximum safety; otherwise the charger and the battery can be damaged violently. And also it can cause a fire to injure a human body or to lose the property.

The charger recognizes 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.

You can set the maximum temperature at which the charger should allow battery to reach during charge. Once a battery reaches this temperature during charge, the process will be terminated to protect the battery. When you start a charge process, the integral safety timer automatically starts running at the same time. This is programmed to prevent overcharge the battery if it proves to be faulty, or if the termination circuit cannot detect the battery full. The value for the safety timer should be generous enough to allow a full charge of the battery. This program sets the maximum charge capacity that will be supplied to the battery during charge. If the delta-peak voltage is not detected nor the safety timer expired by any reason, this feature will automatically stop the process at the selected capacity value.

Glossary of terms
Amps(A): The unit of measure for charge or discharge electric current. The program of the charger will show most of the current in amps(A) at its LCD screen. Milli-amps(mA): The electric current, being amps(A) multiplied by 1000 and noted as 'mA'. So 2.0A is the same as 2000mA (2.0x1000). Or, to convert mA to amps, divide the mA number by 1000. So 200mA is the same as 0.2A. If a current value is below 1.0A, the LCD screen of the charger will still show the current in amps, not milli-amps. For example, a current of 600mA will be displayed as 0.6A, and a current of 100mA will actually be shown as 0.1A. Capacity,milli-amp hours (mAh), and amp-hours (Ah): Charge energy stored by a battery is called capacity, which is defined as how much current a battery can supply constantly over one hour of time. Most hobby batteries are rated for capacity in 'mAh' or milliamp hours. A 650mAh battery can deliver 650mA of current for one hour (650mAx1hr = 650mAh). The batteries of very large capacity, such as lead-acid(Pb) batteries, are usually rated in 'Ah' or amp-hours. A '12V 60Ah' car battery can deliver 60 amps of current for one hour (60Ax1hr = 60Ah). 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. '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).

Maximum circuit power chart

For the voltage of battery is more than 12V, the actual amount of charge current delivered to the battery might automatically be limited, so not to exceed the charger's maximum rated charging power of 50 watts. And also, for the battery having more than 5V, the discharge current delivered to the battery might be limited by the maximum rated discharge power of 5 watts. The actual feeding current will be as follows;
