INTELLIGENT Mode

Intelligent mode: The default intelligent charging mode at startup, the display shows "INTELLIGENT ", and the current gradually decreases when the charging is nearly completed. The intelligent mode is usually used for the conventional maintenance battery charging mode.

Fast charge Mode

Press the red button modulation switch will come into the fast chareg mode,it will display the real charging status. At this time, the screen displays "fast charge", and the current gradually decreases when the charge is nearly completed. The fast charge mode is usually used for emergency charging.

"Electricity" button

The current can be adjusted by manually turning "Current test"

Prompt

There are two modes to choose, after the battery is connected, no personnel care is needed. 1. Under normal circumstances, it is recommended to use smart mode to charge and maintain the battery. 2. For low-temperature, long-term abandoned battery charging, it is recommended to use fast charging mode for repair charging. 3. This product adopts advanced microcomputer automatic management system in front, no matter whether you choose intelligent mode or fast charge mode, there is no need for personnel care

VII. Charging operation

Step 1, Examine and make sure rated voltage of battery is conforming to output voltage of charger. Step 2, Connect correctly the charger and the battery. Step 3, Examine and make sure mains supply voltage is conforming to input voltage of the charger. Step 4, Connect mains supply and the battery, watch to see if the indicator is on and the cooling fan is working when charging. Step 5, if the charger refuse to work, turn off mains supply immediately and check all the connecting cables between mains supply, the battery and the charger.

5-Stage Mode

No-load Mode when there has no load connected with charger,the LED Screen will show voltage only,the power is about 2W; Constant Current means the battery voltage is lower than the set voltage of charger,then the charger supply constant charging current to maintenance both battery and battery charger; Constant Voltage advanced pulse width modulation (PWM) technology,control the charger's current and output voltage accurate,avoid overcharge; Floating charge when the battery is going to be charged full,the charger will stop charging,but still supply constant floating voltage and small current to battery; Trickle charge when the battery voltage and current is approaching the set voltage and current,it will turn to trickle floating charge from automatic mode,it means charge full,also can be charged with floating mode.

User Manual

I. Summary Intelligent computer chips are adopted for whole process control with advanced technologies of pulse width modulation (PWM).This series of products feature small size, safety and flexibility, high conversion rate, stable output current, large designed volume, long-time duration, etc. Short circuit protection, reverse connection protection, overheat protection as well as low voltage protection is available. Therefore, constant voltage and constant current can be transformed reliably from constant voltage status into floating charge status. Hence, power waste and water loss can be reduced during charging process, and battery overheating and bubbling can be eliminated. As a result, battery life is extended greatly! II. Technical parameters Rated input voltage: AC150V-250V Rated working frequency: 50HZ Full conversion rate: 93%plusmn3% Working temperature range: -30℃ TO +35℃ III. Working modes Constant current mode: when battery voltage is lower than charger preset voltage, the working mode is constant current charging mode, where constant charging current is provided by the charger to battery. In this mode, both battery and charger are under good protection. Constant voltage mode: Adoption of pulse width modulation (PWM) can have precise control of charging current and output voltage so that the battery can be fully charged while at the same time not over-charged. Trickle mode: When battery voltage decreases to preset value, charging current will decrease gradually to preset value, and the charger will go into trickle floating charging mode from either constant current mode or constant voltage mode. Even if charging is completed, battery can still be set in floating charging mode. IV. Multiple protections Overheat protection: The charger will close automatically without current output for protective purpose when its temperature is over 105℃, and when the temperature is decreased below about 80℃ or power supply is shut down for 10 minutes, charging process can be resumed. Short circuit protection: In case of accidental short circuit, the charger will close automatically without current output, and beep for alarming. Once correctly connected, charging process will be resumed. Reverse connection protection: Whenever positive poles and negative poles of the charger and the battery are not connected correctly, the charger will close automatically without current output, and beep for alarming. Once correctly connected, charging process will be resumed. Low voltage protection: When single cell voltage is below 1.5V, the charger can not be started up, and beep for alarming. This mechanism is to avoid possible damages caused up by voltage discrepancy between the battery and the charger. V. Warnings ① Dangerous high voltage is contained inside the charger, so please contact your local dealer or the manufacturer in case of equipment failure. ② Do not use under humidity or high temperature, or where there are flammables or explosives. ③ Do not block cooling hole, or use the charger while cooling fan is stopped. ④ Do prevent rain or water entry into the machine to avoid damages. ⑤ Non-professional technicians are strictly prohibited to open the machine or change its purpose. Otherwise, severe injury may be caused. VI. Charging operation Step 1, Examine and make sure rated voltage of battery is conforming to output voltage of charger. Step 2, Connect correctly the charger and the battery. Step 3, Examine and make sure mains supply voltage is conforming to input voltage of the charger. Step 4, Connect mains supply and the battery, watch to see if the indicator is on and the cooling fan is working when charging. Step 5, if the charger refuse to work, turn off mains supply immediately and check all the connecting cables between mains supply, the battery and the charger. VII. Warm Notice For the purpose of a longer service life, avoid charging your battery after it is completely consumed. And, it is always good to charge and discharge this lead-acid battery frequently. If a 12V battery is consumed up (below 10V), firstly the battery will be damaged greatly, and secondly the charger will also be protected due to over-current. This indicates that your battery is below 10V, which is a severe power insufficiency. Do pay attention next time when you using the battery! After only a few minutes or even shorter time, the battery indicates fully charged. 1. Examine to see if there is overcurrent protection, overheat protection or low voltage protection resulted out of non-conforming voltage, and also examine if cooling fan is working. 2. Maybe the battery is consumed up or already fully charged (better test again after discharging or take other battery for testing purpose). 3. Add battery tune-up treatment or distilled water. 4. Examine and make sure output clips from charger is well connected to battery poles.
