26650 Battery Cell 5000mAh | High Capacity CNS BATTERY
Introduction
The 26650 battery cell represents a critical power solution for high-drain applications requiring extended runtime and reliable performance. With a nominal capacity of 5000mAh, CNS BATTERY’s 26650 lithium-ion cells deliver exceptional energy density while maintaining safety standards essential for industrial and commercial deployments. This article examines the technical specifications, application scenarios, and procurement considerations for B2B buyers evaluating 26650 battery solutions.
Technical Specifications and Performance Metrics
The 26650 designation indicates cylindrical cell dimensions of 26mm diameter and 65mm length. This form factor provides approximately 40% more volume than the common 18650 cell, enabling higher capacity without compromising structural integrity. Key performance parameters include:
- Nominal Capacity: 5000mAh at 0.2C discharge rate
- Nominal Voltage: 3.6V-3.7V (Li-ion chemistry)
- Maximum Continuous Discharge: 10A-20A depending on specific model
- Operating Temperature Range: -20°C to 60°C
- Cycle Life: 500-1000 cycles at 80% depth of discharge
- Internal Resistance: ≤35mΩ for optimal power delivery
These specifications make the 26650 cell suitable for applications demanding sustained power output without frequent recharging intervals.
Core Advantages for Industrial Applications
Enhanced Energy Density: The 5000mAh capacity provides extended operational time for portable equipment, reducing downtime associated with battery replacement or charging cycles.
Thermal Management: Larger surface area compared to smaller cylindrical cells facilitates better heat dissipation during high-current operations, enhancing safety margins in demanding environments.
Cost Efficiency: Higher capacity per cell reduces the total number of cells required in battery packs, lowering assembly costs and simplifying battery management system (BMS) design.
Standardization: The 26650 form factor is widely adopted across industries, ensuring component availability and compatibility with existing charging infrastructure.
