The Long Life 18650 Battery is a cylindrical lithium‑ion cell conforming to the 18650 format, featuring a NMC/NCA cathode and a graphite anode. It is designed to deliver high energy density and maintain consistent discharge performance over more than 1000 charge cycles. The supplier highlights compliance with the UN38.3 transport safety test, ensuring suitability for international shipping. Dimensions follow the standard 18 mm × 65 mm size, facilitating integration into a broad selection of devices.
Typical performance specifications include a nominal voltage of 3.7 V and a capacity that usually falls between 2600 and 3500 mAh for cells of this geometry. Standard charging follows a constant‑current/constant‑voltage (CCCV) profile at 0.5 C to a final voltage of 4.2 V, with a 150 mA cut‑off in the CV phase. Discharge testing is performed at 600 mA (0.2 C) down to a cut‑off voltage of 2.5 V, providing a reliable measure of usable capacity. The supplier offers bulk packaging suitable for OEM battery‑pack assembly.
Target applications span power tools, electric vehicles, solar‑energy storage systems and consumer electronics, where long cycle life and stable performance are critical. Buyers can order the cells in large quantities for integration into custom battery packs, with the supplier indicating flexibility in configuration. Trade terms such as FOB or CIF, and payment methods like T/T or L/C, are mentioned, but exact MOQ, lead time and shipping details should be confirmed directly with the supplier.

Importers should first confirm that the supplier can provide the necessary safety certifications, such as UN38.3 test reports and any applicable ISO quality management documentation. Requesting a sample batch allows verification of capacity, voltage stability and physical dimensions before committing to larger volumes. Clarify any required custom packaging or labeling specifications early in the negotiation process.
Logistics for bulk lithium‑ion cells are usually arranged under FOB or CIF terms, with shipment from ports in Jiangsu province. Lead times are not disclosed publicly, so the buyer must ask the supplier to confirm production scheduling and estimated dispatch dates. Payment methods commonly include irrevocable L/C or T/T; the exact terms should be captured in the commercial contract to protect both parties.
Quality control can be reinforced by scheduling a third‑party inspection of the cells prior to loading, focusing on dimensions, voltage, and safety test compliance. Buyers may request a full test report covering capacity, cycle life, and UN38.3 results to ensure the product meets project requirements. Obtaining a Material Safety Data Sheet and Certificate of Analysis alongside the invoice will facilitate customs clearance and regulatory compliance.
