Product Features

  • 01 detail_product

    LARGE CAPACITY: The capacity of 18650 lithium battery is generally between 1800mah and 2600mah.

  • 02 detail_product

    LONG SERVICE LIFE: The cycle life can reach more than 500 times in normal use. which is more than twice that of ordinary batteries.

  • 03 detail_product

    HIGH SAFETY PERFORMANCE: The positive and negative electrodes are separated, which can efectively prevent the short circuit of the battery.

  • 04 detail_product

    NO MEMORY EFFECT: it is not necessary to empty the remaining power before charging, which is conve- nient to use.

  • 05 detail_product

    SMALL INTERNAL RESISTANCE: The internal resistance of polymer cells is smaller than that of general liquid cells, and the internal resistance of domestic polymer cells can even be below 35mΩ.

Cell Electrical Characteristics

No Items Test Method and Condition Criteria
1 Rated Capacity at 0.2C(Min.)0.2C After standard charge, the capacity shall be measured on 0.2C discharge till the voltage discharge to3.0V ≥2520mAh
2 Cycle Life Charging and discharging battery as blew conditions:0.2C standard charge to 4.2V end-off0.2C standard discharge to 3.0V cut-offContinuous charge and discharge for 300th cycles, the capacity will be measure after the 300 cycle. ≥80% of initial capacity
3 Capacity retention The battery to be charge in accordance with standard charge condition at 20~25℃,then storage the battery at an ambient temperature 20~25℃ for 28 days. Measure the capacity after 30 days with 0.2C at 20~25℃ as retention capacity Retention capacity≥85%
