The 18650 lithium-ion battery has become the global standard for rechargeable power. Whether you need high energy density for portable devices or high discharge current for power tools, the 18650 series offers a flexible, reliable, and cost-effective solution.
High Energy Density
Pack more power into a compact cylindrical cell (18mm x 65mm). Ideal for space-constrained applications requiring long runtime.
High Discharge Current
Available in standard (0.5C–1C) and high-drain (10A–30A) versions to support power tools, e-bikes, and vaping devices.
Long Cycle Life
Up to 500–1000+ charge/discharge cycles, depending on cell grade and usage conditions. Reduces replacement frequency and total cost of ownership.
Stable Voltage Platform
Nominal voltage of 3.6V / 3.7V, with a flat discharge curve for consistent device performance.
Built-in Safety
Most 18650 cells include PTC (current protection) and CID (pressure relief), with options for unprotected or protected circuits (overcharge / over-discharge / short-circuit protection).
Wide Operating Temperature
Reliable operation from -20°C to +60°C (charge) and -40°C to +85°C (discharge) for demanding environments.
