Panasonic Ncr21700t Datasheet Official
In the consumer market, you won't find an official Panasonic-branded PDF for the "NCR21700T." This is because these cells were primarily manufactured at the Tesla/Panasonic Gigafactory for exclusive use in Tesla battery packs. Most "NCR21700T" cells found in the wild are actually "pulls"—cells salvaged from Tesla modules—or gray-market units. Core Technical Specifications
The 5,000 mAh rating is industry-leading for 21700 cells available to the public. At 0.2C (1,000 mA) discharge to 2.5V at 25°C, a fresh cell will deliver at least 5,000 mAh. However, at higher drain (e.g., 10A), expect capacity to drop to ~4,600–4,700 mAh due to internal resistance losses. The datasheet’s “minimum capacity” of 4,900 mAh ensures consistency across production batches. panasonic ncr21700t datasheet
