Constant current mode:
When the voltage of battery is lower than the voltage of the charger ,called constant current charging mode.The charger will provide a constant charging current to the battery . There are Protect the battery and charger function.
Constant mode:
Using pulse width modulation (PWM) technology, charger can precise control the charging current and the output voltage .To ensure that the battery is fully charged, the better to avoid battery overcharge.

Trickle mode:
When the voltage of battery is close to the set voltage value of the charging current gradually reduced to the current setting .The charger automatically shift from trickle charge mode to float mode. Charging is completed, it also can continue to float.
Multiple protection:
Over-heat protection:When the temperature exceeds 105 ºC charger turns off, then no current output .When the temperature dropped to about 80 ºC or closed the power supply ,it can be recoverable continued use after ten minutes.
Short-circuit protection: When the charger output happen short circuit ,the charger automatically turns off output and beep alarm.Excluding short-circuit, the connection is automatically restored after properly charging.
Reverse polarity protection: when the charger output positive and negative contrast, the charger will automatically turn off .The output with the battery and the alarm beeps, properly connected automatically resume charging.
Low-voltage protection: When the battery voltage is lower than 1.5V single cell charger protection does not start, and will beep alarm. Avoid battery and charger voltage does not match the damage to the device.
Warned:
1, The Chargers have a high-voltage, danger, such as failure.Please contact your dealer or manufacturer.
2, Non-humid, high temperature, flammable, explosive gas environments use the charger.
3, Non-blocking machine cooling vents or fan stopped using.
4,It is strictly prohibited rainwater from entering the unit, to avoid damage the charger.
5, Prohibited non-professionals to open or modify the machine, or is at your own risk.
Charging operation:
Step 1: Check the rated voltage of the battery to be charged and the charger output voltage is consistent.
Step 2: The charger and battery charge to be properly connected as required .
Step 3: Check the mains voltage and charger rated input voltage is consistent or not.
Step 4: Check the mains voltage and connect the battery, observe the indicator light,.And the charger cooling fan is still working or not.
Step 5: If the charger does not work, please promptly disconnect the mains and check the mains, battery and all the connections.
Tips:
In order to better safeguard your batteries, please do not let the battery run out the capacity ,then to charge battery , it is not a memory cell lead-acid battery charging and suitable use and charge. If the 12V battery capacity is depleted (10V or less). Firstly ,is great harm to the battery , and we will follow because the charger while prone over current protection, then the user can turn off the power to be to continue to use 10 minutes later .This mean your battery has less than 10V, the serious loss of power status. Next time you use the power you have to pay attention.

Easy to troubleshoot failures :
Charger for the battery charging time is only a few minutes, or even less time, has been shown to full power status.
1 Check if the charger because of over-current, over-temperature protection or voltage protection (there is not a consistent voltage) observed cooling fan is working properly.
2 Mean the battery has no capacity or the original full power (discharge recommendations to be re-tested, or choose another shortage of battery tests)
3 Suggest can try to add replenisher to the battery or distilled water.
4 Check the clip and the battery charger output column contact is good or not.
When charge for the battery,the cover of charger fever or full time working ,the battery still can not be displayed.
1 Check whether the battery has a short circuit, leading to long-term can not reach electrical charging voltage setpoint charger.
2 Battery production technology, and the material does not pass .Suggest use genuine battery.
3 Replace the good battery and retest.
When the charger is connected in normal time,have alarm buzzer or does not work.
1 Check the battery voltage is serious loss of electricity or not, then resulting in charger voltage protection (there is not a consistent voltage).
2 Battery shelved indefinitely so dilapidated (belong to scrap batteries) or big resistance , serious short-circuit the battery.
3 Connect the power and space in the load condition is still beeping alarm.
4 Recommended to replace a good battery test again.
On the long-stalled car battery, motorcycle battery (small capacity battery charge) for charging. The charging indicator maybe not show the charge (because the long-overdue or waste battery internal resistance, the demand for current small). Users can put the car headlight or motorcycle headlights to open two minutes and then let the side lights lit (power) and using the charger at the same time. Chargers can immediately determine whether there are quality problems, then the charger indicator light flashes (usually let off after charging indicator float trickle charger .The charger will accordto the needs of high-current of the battery, charge indicator flashes) .
Special note:
1. 12V charger can charge, but the connection 24V it is still indicates 12V. And 24V is not working. Recognition charger 12V voltage range in 8V-14V, 24V voltage range identification in 18V-29V.
2, When the charger work for the battery ,the cooling fan must be running in normal work.
3, with adjustable charger can be adjusted according to the size of the current user of batteries.To better protect the battery. Work began charging time, such as that found in the current indication pin 30A this number. We recommend adjusting knob to about 25A. 25A proposal instance pointer can be adjusted 20-22A . Meaning that retain twenty percent power, in order to better protect the battery and charger

If not urgent need to use the battery, it is recommended to charge the batteries 10/1, that is 10AH battery charging current than 1A.
With manual, automatic charge mode models Description:
Automatic charge mode ,charging to the 12V battery ,the fully charged voltage is 13.8V-14.3V .The charging mode of phones ,the maximum voltage is around 16V.
Hight Quality 20A Car Battery Charger
Automatic mode advantages:
When use automatic mode ,directly connected the power supply to the battery is ok .Do not artificially adjust the charge .Current will require automatic adjustment based on automatic battery .when charge to a voltage position then automatically shut down . The use was smart and convenient. Strongly recommended to use automatic mode.
Manual mode advantages:
When it is an old battery, low temperature (below 0 ºC environment) of the battery, as well as smaller battery capacity, because such battery have a large internal resistance,and the use of the automatic mode will be a small current trickle float phenomenon. Manual charging mode is great for this type of battery internal resistance characteristics, charging program design, there is an auxiliary battery repair function, so that the battery effect will be better. However, when used in manual mode charging must be manually monitored, a slight temperature in the battery casing, stop charging.
Strongly recommended:
When the battery play badly in winter below 0 ºC environment ,then use the full automatic mode .The manual mode also can add more half an hour to 1 hour can make the play better battery performance.
In order to ensure reliable service to provide you, the charger must be installed and used properly. Before installation, please read the installation and operating instructions. This manual should pay particular attention to the warnings and warnings of instruction book. For certain conditions and practices prudent instructions and reminder could result in damage to the charger . Certain conditions and practices may cause personal injury, explicit warnings. Please read all the tips before using the charger .
Please read this manual in order to be used properly. Especially before use, please remember to read the "Safety Precautions" section, to ensure safe use.After reading the manual, please keep along with the warranty card, in order to keep it for reference purposes in the future.
