Import 2600mah 18650 3.7v Original Li-Ion 18650 Battery — Buy in wholesale FOB from Supplier in China

The 2600mAh 18650 3.7V original Li-ion battery from Shenzhen Believe Technology Co., Ltd. is a cylindrical lithium-ion cell measuring 18mm diameter by 65mm length, with a nominal capacity of 2600mAh and a rated voltage of 3.7V. This format is among the most widely produced cylindrical cell sizes globally, serving as the backbone of portable power for consumer and industrial equipment. The supplier operates from Guanghaofeng Industry Park in Shenzhen's Baoan District, a hub for battery and electronics manufacturing in southern China.

The cell chemistry is lithium cobalt oxide or a blended cathode system typical for this capacity class, with a standard charging voltage of 4.2V and a discharge cut-off of 2.5V to 3.0V typical for 18650 formats. Cycle life expectations for 2600mAh cells of this specification generally range from 300 to 500 cycles at 80 percent capacity retention when operated at 0.5C charge and 1C discharge rates. The steel can construction with nickel-plated terminals provides mechanical integrity and weldability for battery pack assembly. Shenzhen Believe Technology Co., Ltd. lists this as an original cell, which in industry terms indicates it is not a rewrapped or secondary-market cell, though buyers should verify the cell's actual provenance and testing documentation.

Primary applications include battery packs for power tools, e-bikes, portable medical devices, LED lighting systems, and energy storage modules. The 18650 format's ubiquity means buyers often source these cells for custom pack assembly rather than end-use as single cells. Importers should confirm with Shenzhen Believe Technology Co., Ltd. the exact cell manufacturer (brand cell or private label), whether the 2600mAh rating is minimum or typical, and what testing protocols are applied to each batch. The supplier's trust tier is harbor, with a response rate showing zero recorded responses, so direct communication channels and sample orders are essential first steps before committing to volume.

Shenzhen Believe Technology Co., Ltd. is located at D1 Building, Guanghaofeng Industry Park in Gushu, Baoan District, Shenzhen, Guangdong Province, China. The company operates within one of China's most concentrated electronics manufacturing corridors, with access to the complete battery cell and pack assembly supply chain. The source provides no information about when the company was established, its registered capital, number of employees, or annual revenue. The trust tier is listed as harbor, which is a baseline platform verification level rather than an audited accreditation.

The listing shows a response rate of 0.00 percent and an average response time of zero hours, indicating that either the supplier has not engaged with buyer inquiries through the platform or the metrics have not populated. There is no mention of factory audits, third-party certifications beyond the ISO and CE references in the product text, or named clients. Buyers should treat the supplier profile as unverified beyond basic registration and conduct independent due diligence, including requesting business licence documentation, factory photographs, and sample cells for independent testing before committing to orders.
