Large batteries like the iPhone 11 Pro Max have strict customs regulations. How do you handle global delivery safely?
We deeply understand that clearing customs is a major pain point for global importers. Our logistics process offers 100% Compliant Dangerous Goods (DG) Shipping with Full MSDS & UN38.3 Certification. We provide safe, direct-to-door delivery via Express, Air, and Sea freight across North America, Europe, South Africa, and the Middle East, making your import process completely hassle-free.
How do you ensure the internal safety and structural stability of these large-capacity iPhone 11 Pro Max batteries?
Every production run strictly follows customized engineering SOPs at our certified facilities. We use professional laser spot welding and multi-layer insulation to ensure precise flex-cable fitting under the on-site supervision of our technical team. Combined with individually insulated heavy-duty packaging, we guarantee zero loose batteries rubbing against each other during transport.
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. Please click the "WhatsApp" button or send a quick inquiry with your target quantity, and our team will provide a tailored volume tier quote within 2 hours.
