Our 12,000㎡ factory locates at Jinhonghui Industrial Park, Tongqiao Town, Zhongkai High‑Tech Zone, Huizhou, China. We own 4 full production workshops (Pole piece, Assembly, Chemical Lab, Packaging), 150 staff including 10 professional R&D engineers and 10 QC inspectors. Daily automated production capacity reaches 250,000 units, annual output hits 300 million batteries. Factory tours & live production viewing are available.
Full set of international compliance certificates for shipping to 60+ countries:
System Certifications: ISO9001, ISO14001, BSCI, IATF16949
All test reports & certificates can be provided for customs clearance & brand audit.
Yes. Our 10‑person R&D team has finished over 1000 customized battery projects for global clients. We equip full testing machines: high‑low temperature tester, charge‑discharge cycle tester, salt spray tester, internal resistance & safety simulation equipment.
We focus on 5 core tech upgrades: high energy density, fast charging, long cycle life, safer eco materials & low self‑discharge performance. We offer free design service under NDA confidentiality agreement for all custom orders.
We provide OEM & ODM manufacturing for worldwide well‑known brands: PHILIPS, Camelion, RAYOVAC, TCL, Vtech, Gembird, OHM etc.
We attend global exhibitions regularly: Canton Fair, Germany IFA, Hong Kong Electronics Fair, India Electronics Show, CES, Vietnam Electronics Show. Our sales network covers North America, Europe, Russia, Southeast Asia, India, Brazil & South Korea.
Compared with common NiMH cells, our factory‑made batteries have 5 competitive strengths:
Ultra‑long cycle life: Rechargeable over 1000 times
Zero memory effect: No need to fully drain before charging, charge anytime
Low self‑discharge (LSD series): Maintain high capacity after long storage, perfect for retail stock
Wide temperature adaptability: Stable discharge from ‑20℃ to 60℃ for outdoor & industrial devices
Matching NiMH battery chargers: EU/US/AU/UK plug, USB multi‑slot chargers, custom charger function & appearance available.
Wide application for consumer & industrial electronics:
Daily consumer: Digital cameras, wireless keyboards/mouses, remote controls, electric toys, electric shavers, Xbox game controllers, cordless landline phones.
Industrial & hobby: RC models, mining lamps, electric wine openers, small robots, cordless power tools, solar lights, portable medical equipment.
We implement 5 strict full‑process QC inspections for every batch:
IQC Raw Material Inspection: Test cathode, anode, separator & shell before production
In‑line Production Patrol: Real‑time sampling during coating, winding, filling & formation
Aging & Cycling Test: All cells go through standardized charge‑discharge aging to filter defective units
OQC Shipment Sampling: Random high‑low temperature & cycle life test before delivery
Automated grading machines ensure tiny voltage difference among same batch cells, greatly reduce after‑sales failure of battery packs.
Standard ready stock cells: No strict MOQ, small wholesale & cross‑border trial orders supported, ship within 1 working day
OEM customized samples: 7‑15 days production, free sample offer (buyer only bears freight cost)
Bulk standard orders: 7‑12 days delivery, automated production lines support stable output even in peak season
Custom battery packs & chargers: 15‑25 days based on structural complexity; we prepare all customs clearance documents synchronously.
Multiple packaging solutions for different sales channels: Blister card, color box, shrink wrap, neutral white box, retail display carton.
Custom eco‑friendly degradable packaging is available. We support printing your brand logo, product specs & multi‑language instructions on all packages for supermarket, e‑commerce & industrial wholesale.
Yes, we supply full set of export documents one‑stop: UN38.3 report, MSDS, CE, RoHS, REACH test reports, packing list, commercial invoice & dangerous goods packaging documents.
All files meet customs standards of Europe, North America, Southeast Asia, Middle East & Korea, no extra third‑party test cost for buyers.
NiMH uses aqueous electrolyte with far lower safety risk than lithium cells, less strict shipping restrictions.
Production transparency: Real‑time workshop photos & production schedule update for bulk orders
Complete after‑sales guarantee: Free replacement for defective goods caused by production flaws
Global exhibition resource sharing: Joint brand promotion & overseas market development opportunities
Absolutely. We supply full technical documents free of charge: charge/discharge curves under different rates, high & low temperature storage curves, official datasheets & battery matching selection suggestions.
Our engineers will recommend the most suitable capacity & discharge rate cells according to your device working conditions to avoid insufficient runtime or capacity mismatch.
Standard NiMH cells: 12‑month factory warranty. Custom NiMH battery packs: 6‑12 months warranty (adjusted by application scenarios).
Any quality defects like insufficient capacity, leakage or short circuit caused by production issues will be replaced or refunded free of charge within warranty period. We provide lifelong technical consultation for battery matching, charging skill & export compliance problems.
