33140 Battery Cell Wholesale Bulk | CNS BATTERY
Professional Guide for Engineers and Technical Procurement Specialists
The demand for high-performance cylindrical lithium battery cells continues to surge across energy storage systems, electric vehicles, and industrial applications. Among various form factors, the 33140 battery cell has emerged as a compelling solution for wholesale bulk procurement. At CNS BATTERY, we specialize in delivering premium-grade 33140 cylindrical cells that meet international quality standards while offering competitive wholesale pricing for global partners.
Understanding the 33140 Battery Cell Specification
The 33140 designation refers to a cylindrical lithium battery with precise dimensional specifications: 33mm diameter and 140mm height. This form factor represents an optimized balance between energy density, thermal management, and mechanical stability. Unlike smaller formats such as 18650 or 21700 cells, the 33140 configuration provides enhanced capacity per unit while maintaining manageable heat dissipation characteristics.
Key Technical Parameters:
- Nominal Voltage: 3.2V (LiFePO4 chemistry) or 3.7V (NMC/NCA chemistry)
- Capacity Range: 5,000mAh to 12,000mAh depending on chemistry selection
- Continuous Discharge Rate: 1C to 5C for standard applications
- Cycle Life: 2,000 to 5,000+ cycles (LiFePO4 variant)
- Operating Temperature: -20°C to 60°C

Why Choose 33140 for Wholesale Bulk Applications?
1. Superior Energy Density and Capacity
The larger physical dimensions of the 33140 cell enable significantly higher capacity compared to conventional 18650 or 26650 formats. This translates to fewer cells required per battery pack, reducing assembly complexity, connection points, and overall system weight. For energy storage systems (ESS) and electric mobility applications, this efficiency gain directly impacts total cost of ownership.
2. Enhanced Thermal Performance
Thermal management remains critical in high-power applications. The 33140 form factor offers improved surface-area-to-volume ratio, facilitating more effective heat dissipation during high-current discharge scenarios. This characteristic reduces thermal runaway risks and extends operational lifespan under demanding conditions.
3. Cost-Effective Wholesale Pricing
Bulk procurement of 33140 cells delivers substantial cost advantages. Manufacturing efficiencies at scale, combined with reduced pack assembly requirements, result in lower per-watt-hour costs. CNS BATTERY maintains strategic partnerships with certified battery manufacturers in China, ensuring consistent supply chain reliability and competitive pricing structures for international buyers.
Quality Assurance and Certification Standards
When sourcing battery cells for commercial deployment, certification compliance cannot be compromised. CNS BATTERY adheres to rigorous quality control protocols aligned with international standards:
- UN38.3 – Transportation safety certification
- IEC 62133 – Safety requirements for portable sealed cells
- UL 1642 – Lithium battery safety standard
- CE, RoHS, REACH – Environmental and regulatory compliance
Each production batch undergoes comprehensive testing including capacity verification, internal resistance measurement, cycle life validation, and safety abuse testing. Documentation packages accompany all wholesale shipments to facilitate customs clearance and end-product certification.
Application Scenarios for 33140 Battery Cells
The versatility of 33140 cells supports diverse application domains:
Energy Storage Systems (ESS): Residential and commercial solar storage solutions benefit from the high cycle life and stable voltage characteristics of LiFePO4 33140 variants.
Electric Mobility: E-bikes, electric scooters, and low-speed electric vehicles leverage the capacity advantages for extended range without excessive pack complexity.
Industrial Equipment: Backup power systems, AGV robots, and portable industrial tools utilize the robust discharge capabilities and long service life.
Marine and RV Applications: Deep-cycle performance makes 33140 cells ideal for off-grid power systems requiring reliable energy delivery over extended periods.
