We source only raw, brand-new A-grade polymer cells directly from top-tier component giants, skipping standard trading markups to pass 10%+ direct savings to you. Because of our rigorous 6-step testing process (from cell grading to final load testing), our real-world batch return rate is kept strictly below 0.3%.
For our standard hot-selling catalog inventory, we can dispatch within 2-5 working days. For large-scale customized OEM or private label orders, production typically takes more days depending on material specifications. We always communicate real-time timeline tracking so you never experience local stockouts.
We back all bulk orders with an ironclad 12-month replacement warranty. If you encounter any functional defectives within the warranty period, you do not need to ship them back to China (which wastes shipping costs). Simply send us a brief video or photo proof of the testing data via WhatsApp/Email, and we will credit or replace them directly in your next shipment.
Yes, for wholesale buyers looking to scale up, we provide premium OEM services. We can handle custom battery body silk-printing, custom-branded retail boxes with anti-static EVA foam or blister inserts, and warehouse barcode stickers.
Our flexible MOQ is designed to help you keep a healthy cash flow without overstocking. For standard replacement models, our minimum starting order is very low.
