18650 li -ion battery
This 18650 lithium-ion cell from Dongguan Sunly Battery Technology delivers 2500mAh capacity at a nominal 3.7V, with a listed current rating of 2A. The cell uses a lithium metal oxide cathode paired with a graphite anode and a LiPF6-based electrolyte, which is the standard chemistry configuration for commercial 18650 cells used across consumer electronics and portable power applications. The cylindrical format measures approximately 18mm by 65mm, fitting standard 18650 battery sleds, holders, and device compartments.
The 2500mAh capacity positions this cell in the mid-range of 18650 offerings, suitable for applications where moderate capacity and reliable cycling matter more than extreme discharge rates. Typical uses include LED flashlights, portable power banks, cordless tool battery packs, and e-bike assemblies where multiple cells are connected in series and parallel configurations. The lithium metal oxide cathode chemistry provides a good balance between energy density and thermal stability, though end-product designs should always incorporate a battery management system to monitor cell voltages and temperatures.
Dongguan Sunly Battery Technology supplies this cell from Dongguan, Guangdong, one of China's primary manufacturing hubs for battery components. Buyers importing for assembly into multi-cell packs should confirm the supplier's capacity matching process, as cells within a pack must have closely matched internal resistance and capacity to avoid imbalance. Request datasheets, UN 38.3 test certificates, and sample cells for independent testing before committing to a production order.
| Cell Format | 18650 cylindrical (approx. 18mm diameter x 65mm length) |
| Nominal Voltage | 3.7V |
| Rated Capacity | 2500mAh |
| Rated Current | 2A |
| Cathode Material | Lithium Metal Oxide |
| Anode Material | Graphite |
| Electrolyte | LiPF6-based |
| Typical Weight | 44-47g per cell (standard for 18650) |
| Typical Charge Voltage | 4.2V (standard Li-ion) |
| Typical Internal Resistance | 30-60 milliohms (varies by cell batch) |
Dongguan Sunly Battery Technology Co., Ltd. is located in Tangxia Town, Dongguan City, Guangdong Province, China. Dongguan is a major production base for lithium-ion cells and battery pack assembly in southern China, with a dense supply chain of cell manufacturers, BMS suppliers, and pack assemblers operating in the region. The company's address places it within this established battery manufacturing cluster.
The supplier's platform profile shows a harbour trust tier with a 0.00% response rate, meaning no tracked buyer enquiries have been answered within the platform's monitoring window. This does not necessarily indicate inactivity, as some suppliers operate primarily through direct channels rather than platform messaging, but it does mean buyers should use alternative contact methods and expect variable response times. Confirm the company's production capabilities, minimum order quantities, and export licensing before placing orders.
This 18650 lithium-ion cell delivers 2500mAh capacity at 3.7V nominal voltage, making it ideal for flashlights, power banks, e-bike battery packs, and portable electronics. Widely sourced from manufacturers in China and South Korea, 18650 cells are the standard building block for multi-cell battery assemblies in consumer electronics and electric mobility applications. When importing, ensure compliance with IATA Dangerous Goods regulations for lithium battery transport and verify UN38.3 testing certification for airfreight clearance.

Sourcing 18650 Li-Ion Battery from Dongguan Sunly Battery Technology Co., Ltd. - China Import Guide
When sourcing 18650 cells from Dongguan Sunly Battery Technology, start by requesting the full product datasheet, including rated capacity, maximum continuous discharge, internal resistance specifications, and any available test reports. The listing provides basic electrical parameters, but a complete datasheet will give you the detail needed to evaluate whether the cell meets your application's requirements. Also ask about the cell's manufacturer and whether it is an original branded cell or a white-label product, as this affects traceability and warranty support.
For logistics planning, confirm the supplier's standard packaging method for export shipments. Lithium-ion cells must be packed in accordance with IATA Packing Instruction 965 (for standalone cells) or 966/967 (when packed with or in equipment), with appropriate Class 9 hazard labelling. Sea freight from Dongguan typically routes through Shenzhen or Guangzhou ports, with transit times varying by destination. Request a detailed quotation that breaks down unit cost, packaging charges, freight estimates, and any applicable export inspection fees. Clarify payment terms and whether the supplier accepts trade assurance or escrow arrangements for first-time orders.
Quality assurance should be an ongoing process, not a one-time check. Establish an incoming inspection protocol that includes voltage verification, visual inspection, and capacity testing of a statistically significant sample from each shipment. For multi-cell pack assembly, invest in cell matching (sorting by capacity and internal resistance) to maximise pack performance and longevity. If you are importing for resale in regulated markets such as the EU or North America, confirm that the cells carry the necessary certifications (UN 38.3, IEC 62133, and any regional marks such as CE or UL) and retain copies of all documentation for compliance audits.
