从China供应商批发进口2200mah Li-Ion Cylindrical Battery — FOB条款

The 2200mAh Li-ion Cylindrical Battery is a rechargeable lithium-ion cell designed for high-demand portable power applications. This 18650-format battery features lithium-cobalt oxide (LiCoO2) or NCM cathode chemistry with graphite anode and uses LiPF6 electrolyte in organic solvent. The cell delivers a nominal voltage of 3.6-3.7V with a typical discharge cutoff voltage of 2.50V, providing reliable energy density for demanding applications. The battery supports discharge rates from 1C to 10C, with the specification indicating capacity retention of 97% at 1C discharge and 95% at 5C discharge rates.

The cylindrical cell measures 18mm diameter by 65mm height (18650 standard format) with typical diameter tolerance of +0.20mm. The battery employs standard charge protocols using 0.2C5A constant current charging to 4.2V limit voltage followed by constant voltage taper charging until current drops below 0.02C5A. Cycle life testing under rapid charge conditions with 5C5A discharge to 2.75V cutoff indicates the cell maintains 80% of initial capacity before end-of-life, representing approximately 500+ cycles under standard test conditions.

This battery serves OEM buyers sourcing cells for power tools, flashlight manufacturers, laptop battery pack assemblers, and e-mobility device producers. The product meets UN 38.3 transport safety standards required for international shipping of lithium-ion cells. B2B buyers include contract manufacturers, electronics distributors, and industrial equipment producers requiring reliable rechargeable power sources in bulk quantities. The cell is sold as a component for integration into finished products rather than consumer retail.

Jiangsu Sunpower Co., Ltd. operates from No. 8, Xingyuan Road, Huangqiao Industrial Park, Taixing City, Jiangsu Province, China 225411. The supplier holds harbor trust tier classification but shows zero percent response rate and zero average response hours in the listing. The company appears to specialize in lithium-ion battery manufacturing with a focus on cylindrical cell production for industrial applications.

The supplier profile does not disclose company registration details, employee count, annual production capacity, or quality certification information. No export certifications, ISO certifications, or third-party audit results are mentioned in the available listing information. The product specification provides detailed electrical characteristics and test methods but lacks information about manufacturing facilities or production capabilities.
