FAQ
Q: Can I request samples and how long is the lead time?
A: Yes, samples are available for performance and quality evaluation. Standard lead time is 3–10 days, depending on specification and customization requirements.
Q: What is the delivery time for bulk orders?
A: For in-stock items, delivery time is 2–7 days.
For mass production orders, lead time is typically 25–30 days, depending on order volume and customization.
Q: Can you provide customized PCM with specific dimensions for narrow cavities?
A: Yes. We specialize in ultra-small PCB designs and can integrate NTCs or specific connectors (e.g., Molex, JST) to fit your internal layout.
Q: Do you offer grading for capacity and internal resistance matching?
A: Absolutely. For bulk orders, we perform 100% automated grading to ensure high consistency in your final product's performance.
Q: What is the warranty period for the 110mAh cells?
A: We provide a 12-month quality warranty from the date of shipment, backed by comprehensive QC reports.
