How to Check the Production Date of Fengfan Battery?
2 Answers
Fengfan Battery's production date can be checked on the surface of the battery, which consists of a series of Arabic numerals and English letters. For example, a Fengfan battery labeled as 4A0735331: 1. 4 indicates production in 2014. 2. A represents January (A is January, B is February... L is December, and so on). 3. 07 stands for the 7th day of the month. 4. In summary, this battery was produced on January 7, 2014. 5. The following 35331 identifier refers to the production unit code and team serial number. Notes for purchasing batteries: It is best to buy batteries from official channels, as there are some small factories in the market that recycle old batteries. The production dates marked on such batteries are basically unreliable, not only lacking good quality assurance (durability) but also lacking overvoltage and overcurrent protection, posing certain safety hazards during charging.
I usually enjoy researching car accessories, and the production date of Fengfan batteries is quite easy to locate. There is a raised code on the top or side of the battery, where the first two digits typically represent the year—for example, 23 stands for 2023. The following letter indicates the month, with A to M corresponding to January to December. For a practical example: if you see a code like 23D12567, it means the battery was produced in April 2023. Some newer batches may include a small triangular arrow symbol next to the date code. A key reminder: if the production date exceeds two years, the battery's activity will significantly decline, especially in summer heat, which can cause electrolyte evaporation. Last time I replaced a battery, I noticed the date was smudged and had to wipe it clean with a damp cloth to read it. I recommend bringing a flashlight when purchasing a battery, as the small print may be hard to see from certain angles.
