FAQ
Q: Can I order samples and how long does delivery take?
A: Yes, samples are available for evaluation and testing. Typical lead time is 3–10 days, depending on specification and customization requirements.
Q: What is the lead time for bulk orders?
A: For in-stock items, delivery time is 2–7 days.
For mass production orders, standard lead time is approximately 25–30 days, depending on order volume and customization.
Q: Is the battery capacity accurate?
A: Yes, all batteries are tested before shipment. Capacity is verified through standardized charge and discharge testing. Actual tested capacity typically meets or slightly exceeds the rated specification within normal tolerance range.
Q: What charging method is used?
A: The battery adopts a standard CC/CV (Constant Current / Constant Voltage) charging profile, which ensures safe charging performance and helps extend overall cycle life.
