Q1. | What is the different between MU charger and traditional car battery charger?
|
|||||||||
A1. | There are two major types of battery charger:
MU Charger using adaptive charging. Charger automatically adjust charging method and auto-cut operation accounting to the actual battery condition. Make the battery always fully charge and have longer life time. |
|||||||||
Q2. | Traditional battery charger have a voltage meter or a current meter to show the charging
status. MU did not have a meter. How can it identify a battery is fully charge or not. |
|||||||||
A2. |
During a battery is charging to it's 80% capacity, the voltage change and charge current will become very small. This makes a analogy voltage/current meter imposible to identify the battery fully charged condition. MU Charger using Micro-processor to continuous analyze the charging change. You just need to select a matched charging capacity(Ah) and voltage, the processor will control the charging voltage and current in 4 charging mode until the battery full. Therefore, you can see the charger LED toggle through "T-B","B-O","O-F" and finally to "F" LED in a short time. |
|||||||||
Q3. | Why my charger still in standby mode even the battery has been connected ? |
|||||||||
A3. | The charge cannot detect the battery: (1) Check battery polarity,terminal and the cables. (2) Faulty battery. |
|||||||||
Q4. | After battery is connected, T & B LEDs flash in cyclic mode and leave T LED flash immediately or only after about 1 min. |
|||||||||
A4. | Abnormal battery voltage: (1) Check the setting of battery voltage. (2) Faulty battery. |
|||||||||
Q5. | After battery is connected, T & B LEDs flash in cyclic mode only. Or It always jumps back to T LED from O or F repeatly. |
|||||||||
A5. | Aged battery with large leakage current. Need to change the battery. |
|||||||||
Q6. | The charger jumps to float charge( "F" LED) after a discharged battery is connected. |
|||||||||
A6. | (1) The set charging capacity is too high. Lower the charging capacity setting (2) Aged battery with large internal resistance. Need to change the battery. |
|||||||||
Q7. | The "F" LED light-on but it restart the charging sequence after several hours, did the charger have any problem? | |||||||||
A7. | Aged battery with large leakage current. The battery voltage drop to abnormal level after
fully charged. Need to change the battery. |
