Import 3000mah Battery 3.7 V 1c — Buy in wholesale FOB from Supplier in China

Shenzhen Jinghongyu Trading Co., Ltd. offers a cylindrical lithium-ion cell rated at 3000 mAh nominal capacity with a 3.7V nominal voltage and 1C continuous discharge capability. The cell measures 18.15 mm in diameter with a plus-or-minus 0.20 mm tolerance, and 65.0 mm in height with a minus 0.50 mm tolerance, dimensions that correspond to the 18650 form factor standardised across the power tool and portable electronics industries. Minimum guaranteed capacity is 2980 mAh, with internal resistance specified at 25 milliohms. The chemistry is lithium-ion, and the supplier targets OEM buyers and distributors serving power tool, electric equipment, and portable electronics markets.

The cell supports a standard charge to 4.2V with a minus 0.03V tolerance, using either 0.5C (approximately three hours) or 1C (approximately two hours) charge current. Maximum continuous discharge current is 3000 mA, equivalent to the 1C rate relative to the 3000 mAh capacity. Cycle life is stated at 500 cycles, though the exact test conditions (depth of discharge, temperature, end-of-life capacity threshold) are not specified in the source. Operating temperature spans 0 to 45 degrees Celsius for charging, and minus 20 to 60 degrees Celsius for discharge. Long-term storage should occur between minus 20 and 25 degrees Celsius, a narrower band than the operational discharge range that reflects degradation risk at elevated temperatures during shelf life.

Typical applications include battery pack assembly for cordless power tools, industrial handheld equipment, and portable consumer electronics where 18650 cells are the dominant format. The low internal resistance figure of 25 milliohms suggests suitability for moderate-drain applications, though buyers designing high-peak-current tools should verify pulse discharge capability separately. The supplier describes itself as a trading company rather than a manufacturer, which affects due diligence priorities, trading companies may offer flexibility but add a layer between buyer and production control. No UN38.3 test summary, IEC 62133 certification, or manufacturer name is provided in the source. Buyers should request these directly before importing, as lithium-ion cells are classified as dangerous goods and face strict transport and customs regulations in most jurisdictions.

Shenzhen Jinghongyu Trading Co., Ltd. is located in Longgang District, Shenzhen, at Ruyi Road in Jinshun Building A. The company holds a harbor trust tier, indicating basic platform verification without advanced assurance. Response rate and average response hours both show zero, meaning no response history is recorded. This absence of data is common for newer or less active listings, but it places the burden of communication verification entirely on the buyer before any financial commitment.

The supplier explicitly identifies as a trading company rather than a manufacturer, a distinction that matters for battery sourcing where cell quality depends heavily on the actual production facility and its process controls. The source description emphasises full capacity, high cycling, low internal resistance, and ultra-low self-discharge, but provides no supporting test reports or manufacturing partner names. No company history, staff size, revenue, export experience, or client list is offered. Buyers should ask for the actual cell manufacturer, factory audit reports, and whether Shenzhen Jinghongyu Trading Co., Ltd. holds any battery-specific export licences or dangerous goods handling certifications.
