18650 Battery Cells
The 18650 battery is a type of rechargeable lithium-ion battery. Its name, “18650,” refers to its dimensions: 18mm in diameter and 65mm in length. These 18650 cells have become widely used due to their compact size and high energy density. These make them suitable for various applications.
Our engineering team mainly chose Samsung, LG, Panasonic, Murata/Sony, and Molicel when designing the Li-ion battery pack. As a professional 18650 battery supplier, our manufacturing centers assemble over 3 million PCS 18650 cells monthly. We can also supply Samsung, LG, Panasonic, Murata, and Molicel 18650 cells bulk to our customers.
MOQ for trial samples order is one full carton- 200PCS, and MOQ for mass production order is one full pallet- approx. 20000PCS, more details can be negotiated.

18650 Battery Cells applications
how to charge 18650 battery
Step 1: Generally speaking, first, you should charge 18650 battery cells with a constant current of 0.2C to the charge cut-off voltage of 4.2V.
Step 2: Rest for 10 minutes.
Step 3: Continuously charge the 18650 battery with constant voltage. The charge current will decrease until the charge current is 0.02C, stopping the charge.
Now, you have completed the whole 18650 battery charging process.
