The Redmi 1S 4G utilizes a removable lithium core exposed to constant mechanical handling. How does your factory ensure the BM44 contacts do not cause intermittent power cutoff?
Supplying replacement packs for legacy removable cell smartphone architectures leaves zero margin for physical frame variance or sub standard copper plating on metal terminals. Sudden device shut downs and loose battery bay fitting happen because generic market trading brokers distribute cheap unverified stocks built with brittle recycled plastic housing to clear out stagnant warehouse leftovers. Times Electronic addresses this structural durability issue directly. We use high grade reinforced structural framing matching original industrial millimeter specifications under calibrated hydraulic pressing tools. Combined with thickened oxidation resistant gold connectors our BM44 accumulator packs sit tightly inside the phone chamber keeping current transmission smooth even under heavy mechanical shaking to protect your localized shop profits.
Sourcing replacement cells for early generation legacy series can involve high logistics asset risk due to chemical passivation. What technical guarantees do you maintain for bulk parts distributors?
We eliminate the risk of receiving unchargeable inactive stock by maintaining active fresh production runs driven by commercial B2B orders rather than liquidating expired legacy warehouse stock that has sat idle for years. Every batch of our heavy duty lithium polymer cores runs through mandatory active capacity grading and rigid aging cycles at our testing hub to break cell passivation completely. This delivers a true full runtime rating status right out of the box. We optimize your distribution logistics through wide multi model smartphone SKU coverage to optimize your freight while routing direct 10 percent plus factory savings straight to you fully backed by a 100 percent pure B2B protection policy where we never sell retail online.













Cell chemistry, format, brand and grade depend on the selected product. LiFePO4 prismatic cells are not polymer pouch cells. For raw-cell orders, confirm the manufacturer, model, capacity, dimensions, terminal format, grading and test data before ordering. For replacement battery packs, confirm the compatible device and required cell/PCB configuration. Our real-world batch return rate is kept strictly below 0.3% through our 6-step testing process.
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.
Our warranty is 12 months from the bill of lading (B/L) dispatch date. No returns to China are required. Send a photo or short video showing the unit SN/QR code and testing anomaly to your account manager. Valid claims are reviewed within 24 business hours. Approved claims may be resolved by replacement in the next shipment or invoice credit; batch defects exceeding 2% qualify for priority replacement dispatch at our cost. Coverage, exclusions and full procedures follow our B2B Support Policy.
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 minimum order quantity is 100 pcs per order. Mixed models are supported. Send your model list and quantities for wholesale pricing; our team will reply within 12 hours. If you need samples for business evaluation before a bulk order, include your company details and expected purchase plan in your inquiry.
Yes. We supply brand-new replacement batteries with professional inspection before shipment.
Each batch is checked for capacity, voltage, internal resistance and overall performance consistency.
Every batch follows quality inspection procedures, including:
This helps maintain stable performance and reduce after-sales issues.
