Technical note: Maximum charge and discharge ratings are not intended for cycle-life operation. Charging current must follow temperature-dependent limits. This unprotected bare cell requires suitable protection and thermal management when integrated into a battery pack.
With 5000mAh nominal capacity and approximately 18Wh of energy, the LR2170SZ offers substantial energy storage in the standard 21700 cylindrical format for energy-focused battery pack designs.
The cell supports a maximum continuous discharge current of 15A at 25°C, offering a balance of capacity and moderate power. This maximum-current rating is not intended for cycle-life operation.
The stated test result is at least 80% of first-cycle capacity after 800 cycles under defined conditions, including 2.5A charging and 5A discharging at 25°C. Actual service life depends on operating conditions.
Charging is specified from 0°C to 45°C, with maximum continuous charging current adjusted by temperature. Battery pack controls should be configured to follow these limits.
The LR2170SZ is intended for integration into professionally engineered lithium-ion battery packs. These potential applications require electrical, thermal and mechanical validation.
Battery packs for electric bicycles, scooters and other light mobility equipment where the cell's current capability and energy capacity meet system requirements.
Rechargeable power modules for portable equipment, mobile power supplies and battery-powered devices requiring a balance of runtime and discharge performance.
Custom power configurations for industrial instruments, robotic systems and OEM equipment designed around compatible 21700 cylindrical cells.
Verify that pack voltage, charge settings, discharge cutoff, series and parallel configuration, and BMS controls comply with the LR2170SZ specifications.
The 15A continuous-discharge rating applies at 25°C and is not intended for cycle-life operation. Charging must follow temperature-dependent current limits.
The unprotected bare cell requires suitable protection circuitry, cell matching, temperature sensing, insulation, cooling and appropriate welded interconnections.
Note: These examples do not imply manufacturer approval for a particular end product. Final suitability requires application-specific validation.
