Panasonic Ncr21700t Datasheet -

Operating or storing the cell above 45°C or below 0°C.

– Good for specific use, poor for general high-drain applications.

At 21mm in diameter and 70mm in height, it is slightly larger than an 18650 but offers a significantly better ratio of weight to power. The Essay: The Silicon-Anode Frontier

Provides the prolonged runtime needed for cordless tools and autonomous vacuum cleaners. panasonic ncr21700t datasheet

The cell maintains a flat discharge curve under moderate loads. At a 5A discharge, the voltage drops slowly from 4.2V to 3.4V before dropping sharply toward the 2.5V limit. Higher current draws lower the effective capacity due to internal resistance and thermal sag. Key Performance Advantages High Energy Density

Due to its moderate continuous discharge rating, the NCR21700T is :

Used in residential solar battery banks and off-grid power stations due to its long shelf-life and density. Operating or storing the cell above 45°C or below 0°C

Panasonic is very clear on this: The NCR21700T is designed for spot-welded nickel strips. Soldering irons transfer too much heat into the cell, melting the internal separator and causing an internal short. If you see a loose NCR21700T with solder blobs on it, run away.

reservoir in a robust 21700 package. Designing within the guidelines laid out in this datasheet ensures safe operation, maximum lifecycle efficiency, and top-tier power performance.

Properly managing charge and discharge cycles ensures optimal cell longevity and prevents thermal runaway. The Essay: The Silicon-Anode Frontier Provides the prolonged

Safety Note: Never fast-charge lithium-ion cells at sub-zero temperatures. Doing so causes metallic lithium plating on the anode, which can cause internal short circuits and permanent structural damage. 6. Key Applications

What is the you are looking at for these cells? NCR21700 data sheet

Ideal for solar wall storage and home backup power due to its compact energy density.

The NCR21700T competes in the low-drain energy segment, but Samsung 50G or LG M50LT are often better choices for similar capacity with slightly higher current.
