Through careful comparison and observation of genuine and fake Nanfu batteries, several simple and practical identification methods have been summarized for your reference.
1. The production date on the bottom of the genuine battery is made up of dots. The production date of the fake battery is a full printed font, not composed of dots.
2. If there is a slight bulge in the center of the small metal bowl of the negative pole of the battery, it is genuine, and if there is no bulge, it is fake.
3. If the "NanFu" and "NanFu" fonts on the battery packaging are pure white, they are genuine, and if they are dark, they are fake.
4. The white "Thunderbolt" stripe in the middle of the real Nanfu battery has serrations, while the fake ones have no serrations.
5. If the fonts "NanFu" and "NanFu" on the battery packaging are pure white, they are authenticticks, and if they are dark, they are fake.
6. If there are words "2001-05 without mercury" (or "2001-03 without mercury") on the negative electrode of the AA-5 (or AA-7) battery, it means It must be 'a fake Nanfu battery, because from March 2001 (March inclusive), the words "mercury-free alkaline battery" are only marked on the side of Nanfu batteries, not on the negative electrode.
7. The sentence “If the appliance is not used for a long time” in the precautions for Nanfu No. 7 real battery has been replaced with “The electric appliance will not be used for a long time. ".
8. Look at the "energy gathering ring". The scythes are all covered with a plastic ring, which can even fall off when picked up. They are very rough and have irregular edges. The real ones are built into the battery. This is the most obvious and easiest way to tell them apart.ed by the quality of the packaging box and the printed fonts.
9. The authentic battery cell case will have a batch number in the center, which is also printed with a dot-matrix machine and will be different for each batch. However, the casing material of the counterfeit product is relatively matte. and does not have this lot number.
Scan the QR code image via cell phone camera. After scanning the Yiwei lithium battery QR code, the relevant information of the battery can be identified, such as production date, production batch, battery capacity, etc. If this information can be recognized normally and matches the information on the battery label, then the QR code is genuine.
