Function description

This product has the advantages of small volume, light weight, high efficiency and convenient use. Besides, it also has the following functions:

10 functions to extend battery life

The function of water loss and current limitation of battery discharge

4. Anti-battery reverse charging function

Short circuit protection function vi. Anti-impact delay start function

7. Wide voltage operation to ensure stable charging parameters

9. Multiple timing protection to protect your battery

Directions for use

1. If the battery is installed in the load, the power supply time should be 6-10 hours. When the power supply lamp is red, it indicates the normal power supply state.Note: it is normal for the indicator light to flash in the short time from red to green.

2. When using, please plug in the output end and then plug in the power plug.

3. Please unplug the power plug before unplugging the output end plug.

4. This adapter must be specially used for the car and cannot be transferred for cross-use to avoid damage.

5. The output of this adapter is dc, with "+" and "one" poles. When using, it must pay attention to the same load.

6. Please avoid violent vibration when using and carrying this adapter.

7. This adapter is strictly protected against moisture, liquid and dust. If any liquid enters, please stop using it immediately. It is strictly prohibited to use in high temperature environment.

8. This adapter shall be kept away from explosive gas and shall be careful against fire or spark when used.

9. Heat is generated during the operation of this adapter, which shall ensure good ventilation in its surrounding environment and shall not be covered by articles: it shall not be used on the surface of sofa or other inflammable materials.

10. The output voltage of this adapter is higher than dc42.4v, please pay attention to safe use: non-professionals should not open it by themselves to avoid electric shock or failure.

11. When using, if the battery is found to be overheated, indicating that the battery has been overcharged, the battery should be unplugged and stopped immediately to avoid damaging the battery.

12. The ventilator adopts fan cooling mode. When the red light is on, the fan must be observed to turn fragrant. If the fan does not turn, it should be stopped immediately.It is normal for an adapter with a fan to work with a certain amount of noise (that is, the sound of air flow when the fan is rotating).

13. This adapter should be placed out of reach of children to avoid injury.

14. The adaptor is of car type, and the manufacturer or professional personnel should be consulted to ensure that it meets the technical requirements of the whole car factory before use.

15. The power cord is damaged. In order to avoid danger, it must be replaced by the maintenance department designated by the manufacturer or by professional qualified personnel.

16. Please read the instructions carefully before use. If any abnormality is found during use, please stop using it immediately.

Common faults:

Failure phenomenon: when used normally, the red light is not on (or only on the green light).

1. The output fuse in the fitting diagram is broken, resulting in no output voltage.This phenomenon is often caused by the mismatch between the positive and negative polarity of the charged battery and the adapter.

2. The output line of the adapter may break

3. The charging socket on the battery box is not connected to the battery line or the adapter output plug is not in good contact with the socket. It may also be the opening of the battery pack connection line or the fuse in the box is broken.

4. Severe sulfuric acid salinization of the battery plate can't be charged due to the failure of the battery pack itself

5. The red luminescent tube of the adapter is damaged.

Fault phenomenon: short charging time

1. The capacity of the battery pack decreases and its performance deteriorates.

2. The capacity of a certain battery in the battery pack is significantly reduced and the voltage is too high.

3. The battery pack is not fully used and has a large amount of power.

Failure phenomenon: unable to turn normally when using normally (i.e. red light cannot turn green light)

1. There is a fault in the battery pack itself. If the battery pack is out of order, the voltage of the battery pack is too low.When charging, the battery temperature rises abnormally and cannot turn.

2. After a certain period of use, due to serious water loss within the battery, the battery cannot normally rotate due to increased current at the end of the battery, abnormal heat of the battery, and even the battery may be filled up.

3. The environment temperature is too high when charging, which makes the leakage current in the battery pack increase, and the terminal current cannot be reduced, which will also lead to abnormal rotation.

4. Individual cases may also be caused by functional failure of the adapter.For example, due to severe vibration, the adapter's control loop will have bad contact or open circuit, resulting in a voltage out of control, so that the battery is overcharged, unable to turn.

Fault phenomenon: indicator light is not on.

Adapter damaged or indicator lamp damaged.
