Product Description
The LG 18650 MJ1 3400mAh 10A Li-ion Battery Cell is a cylindrical rechargeable lithium ion battery designed primarily for devices requiring steady, long-lasting power output. Its nominal voltage of 3.6V and capacity of 3400mAh position it for use in a variety of electronic products, power tools, and portable equipment. Customers sourcing for stable energy delivery with moderate current demands will find this cell applicable.
Engineered with a continuous discharge current rating of 10A and peak up to 20A, this battery maintains consistent electrical performance. It includes low internal resistance (≤18mΩ) which optimizes power efficiency and extends operational cycles, with an expected lifecycle above 800 charge-discharge cycles. International certifications including CE, RoHS, UN38.3, and UL confirm compliance with safety and environmental standards.
The compact form factor (18.5mm diameter × 65.3mm height) is common in lithium ion battery formats, easing integration into existing product designs. Its stable power characteristics align with applications such as portable audio devices, electric bikes, and power tools requiring reliable energy sources. Suitable for OEM and ODM production lines, it is also an option for lithium ion battery wholesale procurement.
