Panasonic Ncr21700t Datasheet Hot (2024)
The datasheet clearly defines a safe operating temperature range of . Operating outside this range, especially in high temperatures, can lead to accelerated aging and potential safety risks. However, when used within its limits, the cell's chemistry demonstrates robust thermal stability.
Here's how the Panasonic NCR21700T stacks up against popular alternatives on the market:
High capacity per cell reduces the total cell count needed. High-Power Power Tools: Cordless vacuums, saws, and drills. panasonic ncr21700t datasheet hot
2. Deep Dive into Discharge Characteristics (When it gets "Hot")
The is an industry-leading cylindrical lithium-ion battery cell that bridges the gap between massive energy capacity and extreme power delivery . Built using advanced Nickel-Cobalt-Aluminum Oxide (NCA) cathode chemistry, this cell features a 5000mAh nominal capacity paired with a continuous current output threshold peaking at 30A . The datasheet clearly defines a safe operating temperature
But in the battery world, “hot” is a double-edged sword. It can mean desirable (high performance, sought after) or dangerous (thermal runaway, capacity loss).
Laptop power banks and solar storage solutions. Medical Equipment: High-energy, reliable power source. Panasonic NCR21700T Here's how the Panasonic NCR21700T stacks up against
At 15A continuous, the cell’s surface can reach ~65°C. That’s hot to touch but still within operating limit (datasheet max 75°C before cutoff). Still, cycle life will degrade faster above 45°C.
The Panasonic NCR21700T (often cited as having a 5000mAh capacity) represents a shift towards high-energy-density cells that still maintain decent discharge capabilities. Key Data Sheet Highlights NCR21700T Size: 21700 (21mm Diameter x 70mm Length) Nominal Capacity: 5000mAh (Typical) / 4850mAh (Minimum) Nominal Voltage: 3.6V Maximum Charging Voltage: 4.2V
The is a high-performance, industrial-grade lithium-ion cell designed to meet the extreme power demands of modern high-drain applications . Originally developed for automotive and heavy-duty industrial use, this 21700 cell is often referred to as "hot" in the enthusiast community due to its exceptional 40A peak discharge capability and its frequent use in Tesla battery architectures.
