从China供应商批发进口3.7v 1000mah Li-Polymer Battery 553450 — FOB条款

The 3.7V 1000mAh Li-Polymer Battery 553450 from Continent Technology Limited is a pouch-type rechargeable cell with a nominal voltage of 3.7V and rated capacity of 1000mAh, manufactured in Shenzhen, Guangdong Province. Its model number 553450 encodes the physical dimensions: 5.5mm thickness, 34mm width, and 50mm length, giving it an ultra-slim profile suited to tight enclosures. The cell employs a lithium cobalt oxide cathode, polymer electrolyte, and aluminium-laminated film shell, a combination that yields higher energy density than equivalent cylindrical formats.

This battery's polymer construction allows flexible form factors and reduced weight compared to cylindrical lithium-ion cells with rigid metal cans. The pouch cell format typically achieves 90-95% packaging efficiency versus 65-70% for 18650 cylinders, a critical advantage in wearable and IoT designs. RoHS compliance is standard for cells exported from Shenzhen manufacturers, though buyers should request the specific test report number for their records. The 1000mAh capacity at 3.7V delivers 3.7Wh of energy, sufficient for day-long operation of Bluetooth peripherals and compact sensors.

Typical applications include IoT devices, fitness wearables, wireless earbuds, portable medical monitors, and OEM battery replacements where space constraints rule out cylindrical alternatives. Buyers in Europe and North America commonly integrate these cells into custom battery packs with protection circuit modules. Continent Technology Limited lists a harbor trust tier and zero percent response rate at time of listing, so direct contact is essential to confirm current production capacity, sample availability, and whether UN38.3 transport certification is held for this specific cell.

Continent Technology Limited is headquartered at B608, Yangguangyayuan, Nanling, Longgang District, Shenzhen, 518100, Guangdong Province, China. The company operates from a commercial address in one of Shenzhen's established electronics districts, with Longgang serving as a hub for battery and consumer electronics manufacturing. Its harbor trust tier indicates a registered and verified business presence on the platform, though this does not constitute a quality or financial guarantee.

The listing shows a 0.00% response rate and zero average response hours, which suggests either a newly established account or inactive communication channels. No verified production floor, ISO certification, or factory audit details are stated in the source data. Buyers should conduct independent due diligence, request a factory profile, and verify whether Continent Technology Limited holds UN38.3, IEC 62133, or UL 1642 certifications for this specific cell before committing to volume orders.
