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.

Frequently Asked Questions

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.

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:

  • Cell quality checking
  • Capacity testing
  • Internal resistance testing
  • Protection board verification
  • Final appearance inspection

This helps maintain stable performance and reduce after-sales issues.

So arbeiten wir – 6. Schritt direkt zu Ihnen nach Hause

 

Jede Batterie durchläuft einen strengen 6-stufigen Prozess – von der Rohzelle bis zu Ihrer Haustür –, damit Sie jedes Mal ein gleichbleibendes, zuverlässiges Produkt erhalten.
Beschaffung von Batteriematerialien 2

01

Direkter Materialeinkauf

Jede Lithiumzelle und jede Schutzplatine wird direkt von zertifizierten Herstellern bezogen. Alle Zellen durchlaufen vor dem Produktionsbeginn eine obligatorische Kapazitätssortierung sowie Lade- und Entladezyklustests, wodurch Chargenschwankungen bereits vor Beginn der Montage ausgeschlossen werden.
Prüfung und Test von Leiterplatten 2

02

Präzisionsanpassung und Qualitätskontrolle vor der Montage

Keine vorgetäuschte Kapazität, keine aufgequollenen Akkus. Vor dem automatisierten Punktschweißen werden alle Zellen anhand präziser Spannungskurven streng aufeinander abgestimmt. Jede einzelne Schutzschaltung (IC) durchläuft parametrische Hardware-Tests, um eine spätere Leistungsminderung oder das Aufquellen zu verhindern.
Fertigungslinie 1

03

Werksmontage

Unsere selbst beschafften Premium-Komponenten werden in zertifizierten Tier-1-Auftragsfertigungsstätten verbaut. Jeder Produktionslauf erfolgt unter strikter Einhaltung unserer maßgeschneiderten technischen Standardarbeitsanweisungen – vom Laserschweißen über die mehrschichtige Isolierung bis hin zur präzisen Montage der Flexkabel – unter der Aufsicht unseres technischen Teams vor Ort.
Test 2

04

Abgeschlossene Batterieprüfung

100% – Gründliche Prüfung vor der Verpackung. Jede Charge fertiger Akkus durchläuft umfassende Kapazitäts- und Kompatibilitätsprüfungen. Sollte auch nur ein einziges Exemplar nicht den Originalstandards entsprechen, wird es sofort aussortiert – es gelangt auf keinen Fall in Ihre Lieferung.
Akku 2 einlegen

05

Hochbelastbare Verpackungen
