K2 Energy 40C/80C 2500-2600mah 3.3V 26650 batter

Place of origin: united states brand name: k2 energy type: li-ion Nominal voltage: 3.2v Size: 26mm*65mm nominal capacity: 2600mah Color: yellow Features: Low self-discharging rate High capacity and discharge rate Good performance Environmental friendly Application: Electric tools, electric bicycle, rc toys, engine start battery and so on. Battery performance: A:discharge characteristics: discharge capacity/nominal capacity¡á100% a)0.2c5a 100% b)0.5c5a 98% c)1c5a 95% d)2c5a 90%. The curves of charging and discharging should be smooth standard charge at 0.2c5a under condition of normal atmospheric pressure and the environmental for 10min and discharge at 0.2c5a, 0.5c5a, 1c5a, 2 c5a to 2.5v respectively. Charge/discharge cycle can be conducted for 3 times before meeting the standards (the same below). B:normal storage residual capacitynominal capacity*85% recoverable capacity nominal capacity*90% ocv decrease¡ü3% internal resistance increase¡ü20% measure initial status and initial capacity. Store for 28 days after standard charge, the measure final status and residual capacity at 0.5c5a to 2.5v;after charge/discharge (0.5c5a/0.5c5a) cycle can be conducted for 3 times, recoverable capacity will be tested at 0.5c5a C:cycle life discharge capacitynominal capacity 80% measure initial status and initial capacity, then conduct 1c5a/1c5a cycle for 1600 times. The discharge capacity shall be measured after 1600 cycle. D:high-low temperature discharge 0.2c5a discharge time stores 3 month-long the batteries 4.5h;stores 6 month-long the batteries 4.25h;stores 12 month-long the batteries 4h.Measure initial capacity and initial status. Battery charge after 3.35v .Measure initial capacity. The distinction room temperature stores 3 months, 6 months, 12 months later, measure battery's final condition, then circulates 3 time record battery's discharge time by 0.5c/0.5c.
