The Xiaomi 4S features a fragile glass back panel with precise internal tolerances. How does your factory ensure the BM38 cells do not swell and crack the phone housing?
Sourcing uncommon niche smartphone batteries in the open market is often a gamble because traditional trading brokers love liquidating expired warehouse leftovers that suffer from chemical passivation and instant power leakage. Times Electronic protects your localized shop profits by eliminating this blind box sourcing entirely. We treat every long tail model with standard flagship rigor through precise direct material buying and fresh manufacturing lots. Every single BM38 unit integrates upgraded heat resistant control ICs that keep internal resistance consistently low under continuous load. This ensures the module operates at a cool temperature to safeguard your storefronts from costly glass damages or internal chassis pressure.
Managing low volume legacy line batteries usually drains our freight efficiency. How does your supply chain minimize this overhead for commercial buyers?
We eliminate purchasing friction by utilizing a massive multi model smartphone SKU catalog alongside highly flexible MOQs allowing you to seamlessly bundle rare legacy lines like the BM38 into your routine flagship shipments. We do not force our partners to overstock dead items. Our lean factory infrastructure routes direct 10 percent plus cost savings straight to your business. Furthermore we protect your unique distribution territory through a strict 100 percent pure B2B protection policy where we run zero retail storefronts on Amazon or eBay ensuring we never compete with your localized wholesale pricing.







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.
