503060 3.7V 1000mAh 3.7Wh Lithium Polymer Battery

Vcell Power 503060 3.7V 1000mAh 3.7Wh Lithium Polymer Battery uses aluminum-plastic composite film packaging, making it lighter and more portable compared to steel-cased batteries like the 18650. Its ultra-thin 5.2mm design allows it to easily fit into compact spaces such as wireless controller handles and small development boards, meeting the design needs of lightweight and miniaturized devices. Providing 1000mAh of power in such a small volume, it can power Bluetooth headsets for tens of hours or provide long-lasting power for development boards during debugging. With a self-discharge rate of less than 1.5% per month, polymer batteries lose very little power when not in use compared to nickel-metal hydride batteries, making them suitable as a backup power source for radios or emergency equipment. It holds multiple international certifications, including CE and RoHS, etc., meeting global market access standards.

FAQ

Q: Can the product discharge at -20°C?

A: Yes. The discharge temperature range is -20°C to 60°C, suitable for outdoor use in cold climates. Charging temperature should be kept between 0°C and 45°C.

Q: What are the main advantages over 18650 steel-case cells?

A: Size, weight, and shape flexibility. The 503060 is only 5.2mm thick and 19.0g, much thinner than the 18mm diameter of 18650. The soft pouch can be custom sized, while 18650 has fixed dimensions.

Q: What OEM customizations are available for this 1000mAh polymer battery?

A: Custom lead length (30-100mm), connector types (PH/XH/JST, etc.), PCM parameters, and surface printing. Sample delivery is arranged based on orders; mass production lead time approx. 25-30 days.

Q: Does this battery meet dangerous goods transport regulations for international shipping?

A: Yes.The 503060 3.7V 1000mAh 3.7Wh Lithium Polymer Battery is UN38.3 certified and compliant with IATA regulations. We provide MSDS, UN38.3 test report, and air/sea transport certificates to facilitate international shipping and export arrangements.

Q: How is the self-discharge rate for long-term storage?

A: Monthly self-discharge is below 1.5%. At room temperature (20±5°C) and humidity below 65%, residual capacity remains good. FIFO inventory management is recommended, avoiding static storage exceeding 6 months.
