## Long description

Samsung INR21700-40T is a rechargeable lithium‑ion cell in 21700 format with a nominal voltage of 3.6 V and a rated capacity of 4000 mAh. The cell is engineered for high‑energy applications where a balance of capacity, steady discharge and compact size is required. Its chemistry and construction provide consistent performance across repeated charge/discharge cycles, making it suitable for use in multi‑cell packs or as a direct replacement for other compatible 21700 cells.
Advantages
The Samsung 21700‑40T delivers a high usable capacity in a single cylindrical cell, offering extended runtime compared with smaller formats. Its stable discharge profile supports devices that demand consistent power output, while the cell’s Li‑ion chemistry enables many charge cycles when used with appropriate battery management. The 21700 form factor provides improved energy density and thermal handling versus 18650 cells, facilitating higher capacity or longer operating times in the same volume.
Suitable for
Electric bicycles (e‑bikes) and scooters
Portable power banks and backup power modules
Cordless power tools and garden equipment
Battery packs for DIY battery assemblies and battery replacement projects
High‑drain devices that require stable discharge
Key specifications
Cell type: Rechargeable lithium‑ion (INR chemistry)
Format: 21700 cylindrical cell
Nominal voltage: 3.6 V
Rated capacity: 4000 mAh
Typical use: High‑energy and high‑drain applications
Construction: Single cell for integration into multi‑cell packs or standalone replacement
How to use
Install the cell following the polarity markings and the device or pack manufacturer’s instructions. For multi‑cell assemblies, use proper cell holders, series/parallel balancing and a compatible battery management system (BMS) to ensure even charging and safe operation. Charge the cell with a charger designed for lithium‑ion chemistry and observe recommended charge current limits to prolong cycle life. Avoid using damaged or visibly deformed cells; replace any cell that shows swelling, leakage or unusual heating.
Usage recommendations
Store and transport cells in a cool, dry place away from conductive materials. For best longevity, avoid storing fully charged or fully discharged for extended periods; a partial state of charge (~40–60%) is preferable for long‑term storage. Always follow safety guidelines for lithium‑ion cells, including using appropriate chargers, protective circuits and avoiding exposure to extreme temperatures or mechanical abuse.
