Dear Amazon,
We are sorry that there is a problem with our product (ASIN: ), which caused confusion between the buyer and the platform. Below we will explain in detail why the problem occurred and what we did.
ASIN：
Title：
1. We submitted the following documents:
A. Declaration of Conformity.
-Attachments 1 and 2 are declarations of conformity and certificates of conformity.
b. Images of each side of the product and packaging showing the address, CE marking and brand and model number of the EU manufacturer or importer
-Attachment 3 is an image of various aspects of the product and packaging.
C. Instructions for use
-Attachment 4 is instructions for use.
General questions:
1. Q: Has a similar incident been reported before? If so, when and how often? What corrective actions have you taken to address the root cause?
A: No similar incident has ever happened.
2.Q: Please provide feedback on what might be causing this event. If you believe the incident was caused by abuse, explain the reason and provide a warning label image and instructions for use as a backup.
A: We have not encountered any such complaints during the use and sale of our products. Therefore, we contacted the technical staff of the purchaser and the manufacturer to summarize the possible reasons for the product charge explosion:
(1) The use environment temperature is too high, causing the lithium battery in the product to withstand excessively high temperatures, which may cause a fire.
(2) Expose the product for a long time, causing the battery to swell and possibly explode together.
(3) Disassemble this product without permission.
(4) Exposure to flame during use.
(5) Use more than the rated power, the car style can only be used for cars
3. Q: Do you plan to take corrective action after becoming aware of this incident? If so, describe and indicate when these corrective actions are completed.
Answer: 1. We are willing to contact the buyer to resolve this issue. However, we are unable to confirm the customer information of the complaint at this time, and the after-sales email we sent has not received a response. We promise that for product quality issues, we will definitely take responsibility for product return, replacement and compensation.
- (1) We will strengthen the inspection of products in the following ways.
A. High simulation test: under the condition of pressure ≤ 11.6kpa and temperature 20±5℃, the battery should be stored for more than 6h to detect whether the battery has leakage, no exhaust, no disintegration, no combustion, no explosion, no damage and other phenomena, and the voltage should not be less than 90% before the test.
B. Temperature test: to test whether the high temperature.
C. Vibration test: make the fully charged battery subject to round-trip vibration of different frequencies to test whether there is battery explosion, fire, liquid leakage, problem solving and excessively high temperature.
D. Impact test: the fully charged battery is subjected to impact collision of different extents to prevent the battery from exploding, catching fire, leaking liquid and excessively high temperature after forced discharge.
E. External short circuit: short circuit the fully charged battery, test whether there is battery explosion, fire, liquid leakage, high temperature phenomenon.
F. Heavy impact/extrusion: under heavy impact, to prevent the battery surface temperature is too high.
G. Overcharging: prevent the battery from expanding and exploding
H. Forced discharge: it is mainly to prevent the phenomenon of explosion, fire, liquid leakage and excessively high temperature of the battery after the forced discharge.
(2)We require the supplier to produce the product inspection report upon delivery. The report must include the eight inspection steps described above.
(3) before shipment, we will also conduct boot test to ensure the normal use of the product.
3. We have not listed all the instructions and precautions in the list before (the product description manual describes it in detail). To ensure this, the company asks editors to add all considerations to the list when selling products, as follows:
(1) Do not use this product when the ambient temperature is high.
(2) Do not expose the product to prolonged exposure.
(3) Do not prevent explosive items in the use environment
(4) Do not touch open flames during use.
(5) Do not disassemble this product
4. We will indicate on the product page that if the buyer has any questions before, after or during the use of the product, please contact our customer service staff in time, we will definitely resolve all product-related questions.
5. The company will arrange a special person to be responsible for recording the negative feedback and return reasons of customers every day. Whether it is for the product itself or our service, logistics, etc., we will make improvements as soon as possible.
6. We will maintain close contact and communication with suppliers, and hold meetings twice a month to discuss customer feedback on the product. Improve product shortcomings as soon as possible. At the same time, if the supplier updates the performance and appearance of the product, it must notify us two months in advance and provide detailed performance parameters and design drawings.
4.Q: As far as you know, have any design changes been made to this product recently? If so, when did it change?
A: There have been no recent design changes to the product.
5.Q: is this product included in the recall?
A: the product has not been recalled.
