Where is the production date located on a Fengfan battery?

The production date of a Fengfan battery is located on the surface of the battery. Here are the specific details about the production date of Fengfan batteries: 1. Purpose of the production date: Although the production date of a car battery is not unique, it plays a decisive role in checking the aging degree of the battery. 2. Production date coding method: The production date of a Fengfan battery consists of a series of Arabic numerals and English letters. For example, a Fengfan battery labeled as 4A0735331 indicates that 4 represents the year 2014, A stands for January, 07 represents the 7th day of the month, and 35331 is the production unit code and team serial number.
The date code of Fengfan batteries is usually engraved on the battery cover, and the position is not fixed, but you can definitely find it if you look carefully. It is commonly located near the edge on the top of the battery or near the positive and negative terminals on the side. The date code is a combination of letters and numbers, such as B20230809, where B represents production in Baoding, and the following eight digits indicate the production date (year, month, and day). If the battery was purchased in the last two years, the date code may have been changed to a QR code plus numbers, with the numeric part still representing the year, month, and day. It's best to bring a flashlight when searching, as many car battery compartments are dimly lit and covered in thick dust. If you really can't find it, remove the battery and check the bottom edge—some models have the date stamped there. Remember to clean the surface before checking the date. Last year, when I helped a neighbor check their battery, a layer of dust almost made an 8 look like a 3.
Checking the production date is actually quite simple. I always look at this first when replacing the battery. For Fengfan batteries, the date code is either in the middle of the top cover or next to the side label. The newer models now use laser engraving, where you need to look for a continuous string of six or eight digits in the long character sequence. For example, if you see '22D01', it means April 1, 2022, with 'D' representing April. For newer models after 2023, simply look for an eight-digit date in the format of year, month, and day, such as '20230415'. For batteries produced a few years earlier, the code might be a combination of letters and numbers, like 'G200318', where 'G' stands for July, followed by the year, month, and date. When checking, be careful not to have the view blocked by the positive terminal cover. Some SUVs have tricky battery placements, so you might need to use your phone to take a photo by reaching inside.
Here's a trick: First locate the raised characters on the battery surface. The production date of Fengfan batteries is usually printed near the handle on the cover plate or around the electrolyte filling port. Yesterday when helping a colleague check his start-stop battery, the date was hidden below the side barcode. New batch batteries directly display the year, month, and day, while older models use a letter plus the last digit of the year followed by month and date codes. For example, F190827 means it was produced on August 27, 2019. If you see a sticker label, pay attention to the small print in the bottom right corner which may also contain production batch information. When you really can't find it, wipe the entire battery surface with a damp cloth - laser-etched codes become particularly visible when wet.
