Hello, I am a lithium battery engineer from Jiangxi Foster New Energy Group. I will answer you from a professional point of view.
Battery cell inkjet coding includes three parts：
Battery cell model + batch number battery + battery sequence code
18650?+ 6J52114?+ 37503
Your capacity is digital 2000, 2014 For batteries shipped on October 21, 2019, you can see if the logo on it is an F. If it is a Foster drum, you can see that it was produced by Factory Five. If you don't understand, you can ask!
How much does 18650 3400 mAh lithium battery weigh?
Hello, I am a technician from Jiangxi Foster New Energy Group, I will tell you from one point from a professional point of view. , it depends on the voltage and capacity it has to determine the price. The higher the voltage, the larger the capacity, the higher the price.Now let's take the most common large-capacity electric vehicle battery as an example. 3.7V 12Ah, this capacity requires 1 series and 6 parallel, that is, 6 18650 batteries with a power of 2000 mah, the unit price is 6.5 yuan, which costs 39 yuan plus handling fee and shipping protection card, the total cost is almost. Ex-factory price of 50 yuan, if the dealer sells it, it should be more than 60. It is purely handmade, I hope it can help you
How many milliamps does the Does lg18650 voltage 4.1v have?
Some 18650 lithium batteries on the market have a false standard phenomenon, 3400 mAh It is difficult to confirm whether it really has such a high capacity . Here are the weight values of some physical 18650 batteries for your reference:
Disassembled battery, marked 1300mah, without protection. plate, flat head.
Battery removed from x-live mobile power supply has no plprotective aque and a flat head.
Domestic divine fire, pointed tip, with protective plate, marked 3500mah, the actual value is about 1300mah.
1. LG18650 4.1V voltage is generally 2000-2500mA.
2. Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. It is different from rechargeable batteries, lithium-ion batteries and lithium-ion. polymer batteries. The inventor of lithium batteries is Edison. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronic technology in the late 20th century, the number of miniaturized devices increaseded day by day, placing high demands on power supplies. Lithium batteries then entered the stage of large-scale practical use.
