Features:
Low self-discharging rate
High capacity and discharge rate
Good performance
Environmental friend
Applications:
Wide application: electric tools, electric bicycle, RC toys, engine start battery and so on.
Battery performance:
B: Normal Storage
Internal Resistance increase≤20%
A:Discharge characteristics:
Discharge capacity/Nominal capacity×100%
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
Internal Resistance increase≤20%
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
, 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 capacity≥Nominal Capacity*80%
Measure initial status and initial capacity, then conduct 1C5A/1C5A cycle for 1000 times. The discharge capacity shall be measured after 1000 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.
