Panasonic Ncr21700t Datasheet Hot Review

Retains approximately 80% capacity after 500 to 1,000 cycles depending on discharge severity. Thermal & "Hot" Operation Limits

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).

Suggest to keep it running cool. Let me know how you'd like to proceed! NCR21700 data sheet panasonic ncr21700t datasheet hot

: Rated for over 1000 cycles , making it a durable choice for long-term projects. Retains approximately 80% capacity after 500 to 1,000

The datasheet for the Panasonic NCR21700T provides a comprehensive overview of the battery's specifications, including:

Why the word hot ?

The datasheet mandates that the cell surface must never exceed 60°C during continuous discharge . If an application pushes the cell into high current zones causing it to run hot, active thermal management (forced air or liquid cooling) must be integrated into the battery pack design.

The search for a reliable high-capacity, high-drain cylindrical cell frequently leads engineers and battery enthusiasts straight to the Panasonic NCR21700T Suggest to keep it running cool
