How to Check the Production Date of Fengfan Battery?
1 Answers
Fengfan battery production date is composed of a series of Arabic numerals and English letters, located on the surface of the battery, representing the year, month, and day of production. The following is a related introduction: 1. Fengfan battery labeled 4A0735331: For example, a Fengfan battery labeled 4A0735331, where 4 indicates production in 2014, and A represents January (A is January, B is February... L is December, and so on), 07 represents the 7th day of the month. In summary, the battery was produced on January 7, 2014. As for the remaining 35331 label, it refers to the production unit code and team number. 2. Precautions for purchase: It is best to purchase the battery 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 a good guarantee in terms of quality (durability) but also lacking overvoltage and overcurrent protection, posing certain safety hazards during charging.
