The Samsung SDI ICR18650-22P is an NMC lithium-ion cell with 2200mAh rated capacity, 3.62V nominal voltage and a specified 10A maximum continuous-discharge current. Its standard 18650 dimensions, defined high-rate cycle performance and broad discharge-temperature range support professionally engineered portable equipment, instrumentation and custom battery packs requiring a balance of energy capacity and moderate-to-high current output.
The ICR18650-22P uses Li-NiMnCoO₂ chemistry and provides 2200mAh rated capacity at a 0.2C discharge rate. Minimum capacity is specified as 2050mAh at 0.2C and 2000mAh at 1C, helping engineers distinguish low-rate capacity from performance under a higher load.
The supplied specification lists a maximum continuous-discharge current of 10A with a 2.75V end voltage. This rating applies at an ambient temperature of 0°C to 45°C, and the cell temperature must remain below 60°C through appropriate monitoring, cooling and current control.
CC-CV charging is specified with a 4.20 ± 0.05V charge-end voltage and 43mA termination current. Standard charging uses 1075mA with a three-hour limit, while rapid charging uses 2150mA with a 2.5-hour limit under controlled charging conditions.
The datasheet specifies at least 700 cycles with more than 70% rated capacity using 0.5C charging and 1C discharging. A second high-rate profile specifies at least 300 cycles with more than 80% remaining capacity using 1C charging and 3C discharging.
Internal resistance is specified at no more than 35mΩ using a 1kHz AC measurement. The cell also carries a charge-retention value of at least 90% after one month at 60°C, while an ideal storage state of charge between 40% and 60% is recommended.
The cell measures 18.2 ± 0.2mm in diameter and 64.8 ± 0.2mm in height, including its label, with a specified weight of 44.5 ± 2g. These dimensions support established cylindrical-cell holders and compact series-parallel battery configurations.
Custom battery pack applications: Suitable applications include portable instruments, professional electronics, lighting systems, monitoring equipment and moderate-to-high-current battery assemblies with validated electrical and thermal demands. MisenBattery supplies Samsung SDI cells and supports custom pack integration using a compatible BMS, fuse protection, welded interconnects, voltage and temperature sensing, cell insulation, safe spacing, and appropriate thermal and mechanical design. Supporting CE, UN38.3, RoHS and UL documentation can be provided for the applicable product and shipment.
