FAQ For TWS Earbuds Batteries

A: We can produce coin cells with diameters as small as [e.g., 6mm] and pin-type cells with diameters under [e.g., 4mm]. The final size is a balance with the required capacity.

A: Due to the highly automated and specialized manufacturing process, our MOQ for custom TWS batteries typically starts at 50,000 to 100,000 units.

A: We utilize advanced, high-voltage cathode materials, silicon-composite anodes where applicable, and precision stacking/winding techniques to minimize inactive components and maximize energy storage volume.

A: Our TWS batteries are engineered to retain over 80% of their initial capacity after 500+ charge cycles, ensuring a long and reliable product life for the end-user.

A: Yes, we can formulate the cell chemistry and design the protection circuit to safely support higher charging currents, reducing overall charging times.

A: After design finalization, the lead time for the first batch of micro-battery prototypes is generally 5-7 weeks.

A: Our dedicated TWS battery lines are highly automated, from material coating to final testing and grading. This automation, combined with stringent in-process quality control, ensures extremely high consistency.

A: Yes, we provide a complete ecosystem solution. We manufacture both the miniature batteries for the earbuds and the higher-capacity rectangular battery for the charging case.

A: Absolutely. We manage the entire certification process to ensure your batteries meet all required standards for your target markets, including IEC 62133, UL, CE, PSE, KC, and UN38.3.

A: Please provide the target dimensions for the cell (diameter/length/width/thickness), required minimum capacity (mAh), voltage (3.7V), any fast-charging requirements, and your estimated annual volume.
