Core Manufacturing Capabilities for AA Rechargeable Batteries

1. Specialized Production Infrastructure

Dual Production Bases: Two purpose-built facilities (total area 45,000㎡) with dedicated workshops for AA battery electrode manufacturing, cell assembly, formation, and packaging. The layout is optimized for AA format’s unique dimensions (14.0×50.5mm), ensuring seamless production flow.

AA-Specific Production Lines: 28 automated lines exclusively for AA rechargeable batteries—16 for NiMH and 12 for lithium ion. Key equipment includes precision electrode coating machines, AA-sized winding systems, and temperature-controlled formation stations, all calibrated for AA battery performance.

Scalable Capacity: Annual production capacity of 60 million units (40 million NiMH + 20 million lithium ion), supporting bulk orders (100,000+ units/month) and small-batch customizations (MOQ 1,000 units). Flexible line configuration adapts to different capacity and performance requirements.

Smart Manufacturing System: MES (Manufacturing Execution System) integrated across all lines, real-time monitoring of production parameters (electrode thickness, charging efficiency, cycle life) to ensure batch consistency.

2. Core Technology & Product Portfolio

Lithium Ion AA Rechargeable Batteries (14500)

High-Energy Density: Capacity range 1000–2000mAh, 3.7V nominal voltage, ideal for high-power devices like digital cameras and portable tools.

Long Cycle Life: Advanced cathode material modification (LiCoO2/NCM) enables 1000+ charge-discharge cycles (80% capacity retention), outperforming standard rechargeable batteries.

Fast-Charging Support: Compatible with 1C fast charging, reducing full-charge time to 1–2 hours while maintaining battery lifespan.

NiMH AA Rechargeable Batteries

Low Self-Discharge: Patented electrolyte formula minimizes self-discharge (≤3%/month at 25℃), retaining 80% capacity after 12 months of storage—suitable for infrequently used devices like remote controls.

Stable Performance: Capacity range 1300–2700mAh, 1.2V nominal voltage, consistent discharge curve for devices like toys, flashlights, and smart home sensors.

Eco-Friendly Design: Mercury-free, cadmium-free construction, compliant with global environmental standards for sustainable use.

3. Strict Quality Control System

Full-Cycle Inspection: Quality checks embedded at every stage—raw material screening (nickel powder, lithium compounds purity testing), in-line electrode alignment inspection, cell charging/discharging testing, and final batch sampling.

Professional Testing Laboratory: On-site facilities with cycle life testers, high-temperature stability chambers, and safety test equipment (short-circuit, overcharge, impact). Each AA battery undergoes 50+ performance and safety tests before shipment.

Global Compliance Certification: Products meet UN38.3, UL 1642, CE, RoHS, and ISO 9001 standards. NiMH batteries additionally comply with IEC 61951-2, while lithium ion variants adhere to IEC 62133.

Traceability Management: Unique QR code for each battery, linking to raw material batches, production data, and test results—ensuring complete transparency for clients.

Application-Specific AA Rechargeable Battery Solutions

Consumer Electronics: High-capacity NiMH AA batteries for digital cameras, portable audio devices, and game controllers—balanced power output for prolonged use. Lithium ion variants for high-drain devices like professional flashlights.

Smart Home & IoT: Low self-discharge NiMH AA batteries for smart sensors, remote controls, and security cameras—long standby life reduces replacement frequency.

Outdoor & Sports Equipment: Rugged lithium ion AA batteries with wide temperature adaptability (-20℃ to 60℃) for GPS trackers, portable lighting, and camping gear. NiMH options for solar-powered outdoor devices.

Industrial & Medical Devices: High-stability AA batteries for industrial sensors, portable medical tools, and emergency equipment—reliable performance in critical scenarios, with custom cycle life optimization.
