The Redmi Note 5 features a tightly spaced inner chassis supporting a large cell. How does your factory guarantee the BN45 battery does not expand and crack customer screen modules?
Sourcing replacement cells for legacy high volume device lines requires absolute mechanical precision regarding physical outer thickness and thermal safety metrics. Screen yellow spots and casing misalignment happen because traditional market trading brokers distribute cheap unverified stocks built with high resistance recycled elements to undercut market pricing. Times Electronic eliminates this localized repair liability completely. We utilize fresh premium density lithium components compressed to precise original millimeter profiles under calibrated hydraulic tools. Our BN45 modules maintain an ultra-low internal resistance curve even under continuous multi tasking keeping the unit completely cool and flat to protect your localized shop profits.
Since managing legacy budget series components often involves high capital risk due to bad batches what technical guarantees do you provide to bulk buyers?
We eliminate cross border transit defects and inventory dead weight by maintaining active fresh production runs driven by commercial B2B orders rather than liquidating expired legacy lots that have degraded over the years. Every batch of our industrial mobile batteries runs through mandatory active capacity grading and rigid aging cycles at our testing hub to break cell passivation completely delivering a true 0-cycle power component status right out of the box. We optimize your distribution logistics through massive multi model smartphone SKU coverage with highly flexible MOQs routing direct 10 percent plus factory savings straight to you fully backed by a 100 percent pure B2B protection policy where we never sell consumer 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.
