The misenpower INR26650C is a rechargeable 26650 lithium-ion cell combining 5000mAh typical capacity, approximately 18.5Wh nominal energy and a verified 5A quick-discharge rating. Its cylindrical format is suitable for professionally engineered battery modules requiring balanced energy storage and moderate current delivery. Pack designers should evaluate operating temperature, electrical limits, cell matching, protection architecture and thermal conditions against the requirements of the finished application.
With a typical capacity of 5000mAh and a minimum capacity of 4950mAh under the specified 0.2C test conditions, the cell provides approximately 18.5Wh of nominal energy. This capacity profile supports battery modules where operating time and compact cylindrical packaging are more important than extreme continuous-current performance.
The specification identifies a 5000mA, or 1C, quick-discharge current. This makes the INR26650C appropriate for moderate-current systems when pack voltage, parallel configuration, conductor sizing and thermal behavior are engineered correctly. Final pack validation should confirm voltage drop, temperature rise and usable capacity under the application's actual duty cycle.
A maximum instantaneous discharge value of 15A appears in the manufacturer specification, but its allowable duration, repetition interval and temperature conditions are not defined. It should not be advertised as a continuous or fully specified pulse rating. Any short-duration high-current use requires written confirmation and application-level electrical and thermal testing.
Standard charging uses a controlled 1A constant-current stage followed by constant-voltage charging at 4.20V, terminating at 100mA. A 5A quick-charge current is also listed. Charging must remain within 0°C to 45°C and be managed by a compatible charger and protection system designed for the finished pack configuration.
The documented operating window covers charging from 0°C to 45°C and discharging from -20°C to 60°C. Available capacity decreases at low temperatures, with the specification indicating 60% capacity at -20°C under its stated test method. Pack controls should restrict charging and discharging when cell temperatures fall outside approved limits.
Under the manufacturer's specified 0.5C charge and discharge cycle procedure, the cell is rated for at least 300 cycles while retaining more than 80% of its initial capacity. Actual service life depends on depth of discharge, temperature, charge voltage, current demand, storage conditions and the effectiveness of pack-level protection and balancing.
Custom battery pack applications: Suitable applications may include portable power equipment, industrial instruments, backup power, energy-storage modules and moderate-current battery systems. MisenBattery supplies misenpower cells and supports custom pack integration with an appropriate BMS, fuse, welded interconnects, voltage and temperature sensing, insulation, cell spacing, mechanical restraint and thermal design. Supporting CE, UN38.3, RoHS and UL documentation can be provided when available for the applicable product, pack and shipment; the supplied specification does not identify certificate numbers.
