Using QR codes to identify the authenticity of batteries is a common anti-counterfeiting method, especially for lithium battery products such as 18650 batteries. There are a large number of counterfeit and shoddy products on the market, so it is very important to master the identification method. The following are detailed steps and methods:
I. The basic principle of QR code anti-counterfeiting
1. Uniqueness
Each genuine battery's QR code is unique, containing information such as the product's production batch and serial number.
2. Encryption technology
QR codes are usually bound to a database, and authenticity can be verified by scanning.
3. Anti-counterfeiting query platform
The brand will provide official query channels (such as official websites, WeChat public accounts, APPs, etc.).
II. Steps to identify the authenticity of batteries
1. Check the appearance of the QR code
- Genuine QR codes are clear, with sharp edges, without blur or ghosting.
- Counterfeit QR codes may be printed roughly or even unscannable.
2. Scan the QR code
- Use a mobile phone scanning tool (such as WeChat, Alipay, or a dedicated anti-counterfeiting APP) to scan the QR code.
- Note: Some brands may need to use an official APP.
3. Verification information
- After scanning, the system will display relevant information about the battery (such as production date, batch number, etc.).
- Genuine batteries will prompt "First query" or "Authentic verification passed".
- Counterfeit batteries may prompt "Invalid QR code" or "Has been queried multiple times".
4. Check information consistency
- Check the information displayed on the QR code with the information on the battery packaging (such as model, capacity, production date, etc.).
- If the information is inconsistent, it may be a counterfeit product.
5. Repeat query detection
- If the QR code is queried multiple times (especially in a short period of time), it may be a counterfeit product.
- Genuine QR codes can usually only be queried once or a limited number of times.
III. Precautions
1. Purchase through official channels
Try to choose the brand's official flagship store or authorized dealer to avoid purchasing batteries of unknown origin.
2. Beware of low-price traps
Counterfeit batteries are usually much cheaper than genuine ones, but their performance and safety cannot be guaranteed.
3. Check the packaging and labeling
- Genuine batteries have exquisite packaging, clear labels, and no printing errors.
- Counterfeit batteries may have spelling errors, blurred labels, and other problems.
4. Anti-counterfeiting label integrity
Make sure the QR code anti-counterfeiting label has not been damaged or tampered with.
IV. FAQ
Q1: What should I do if there is no response after scanning the QR code?
It may be a counterfeit QR code, or the network problem cannot connect to the database. It is recommended to change the network environment or use the official APP to rescan.
Q2: Is it necessarily a fake if the QR code shows "has been queried many times"?
Not necessarily, it may be scanned by other users by mistake. But it is recommended to contact the brand customer service for further verification.
Q3: Is the battery without a QR code necessarily a fake?
Not necessarily, some old batteries or low-end brands may not use QR code anti-counterfeiting technology. But it is recommended to give priority to products with anti-counterfeiting labels.
Q4: Can QR codes be forged?
Yes, but forged QR codes usually cannot be connected to the official database, or the information displayed does not match the packaging.
V. Recommended tools and resources
1. Brand official APP
Brands such as Panasonic, Samsung (SDI), LG, etc. usually provide dedicated anti-counterfeiting query tools.
2. Third-party anti-counterfeiting platform
Such as China Anti-Counterfeiting Code Query Center, etc.
3. Battery parameter query tool
Further verify the authenticity through information such as battery model and capacity.
Conclusion
Identifying the authenticity of batteries through QR codes is a simple and effective method, but it needs to be combined with other anti-counterfeiting methods (such as packaging inspection, parameter verification, etc.) for comprehensive judgment. Be sure to choose regular channels when purchasing to avoid buying counterfeit and shoddy products for cheapness, which will affect the performance of the equipment and even cause safety hazards.
