Product Details
The GEB 18650 3.6V 1300mAh High-Drain Cylindrical Lithium-ion Battery Cell (18×65mm) is an industrial-grade cylindrical power cell engineered for high-current electric mobility and power tool applications. Delivering a verified 3.6V nominal working voltage and 1,300mAh rated capacity (4.68Wh energy content), this cell features an internal low-impedance current collector structure (≤ 22–30 mΩ), enabling sustained 10C continuous discharge (13A) and up to 15C pulse delivery (19.5A ≤ 5s). Equipped with an integrated pressure-relief safety vent (CID/PTC) and precision steel casing, it ensures excellent thermal integrity during intensive cyclic operation. Prior to multi-cell module assembly, verify pure nickel strip thickness, automated cell sorting parameters (ΔV ≤ 3mV, ΔR ≤ 1.5mΩ), and 4.20V charger cutoff threshold.
Product Overview
The GEB 18650 3.6V 1300mAh High-Drain Cylindrical Lithium-ion Battery Cell provides optimal discharge rate capability and thermal stability for demanding cordless equipment. With precise physical dimensions of Ø 18.2 ± 0.2 mm × H 65.0 ± 0.3 mm and a calibrated unit weight of Approx. 44.0g ± 1.5g, this cell is manufactured under cleanroom conditions with automated sorting to ensure batch-level consistency. Designed for electric gardening tools, cordless drills, vacuum cleaners, and high-drain custom battery packs, it supports flexible terminal configurations including standard flat top, button top, and factory-welded pure nickel solder tabs.
