Per attached drawing
5.1 TEST CONDITIONS
The test is carried out with new batteries (within a month after delivery)
Standard charge : 4mA×14hours
Standard discharge : 0.2C to 3.0V
5.2 TEST METHOD & PERFORMANCE
|Up to 3 cycies|
|≥3.9||After 1 hour standard|
|mΩ/cell||≤1500||Upon fully charge|
|Over charge||No leakage|
Storage: 28 days;
|Leakage||No leakage nor|
|Fully charge at 4mA,|
Stand 14 days
Note 2 IEC285(1993)4.4.1 cycle life
|1-50||4mA for 14h||8mA for 5h|
50 cycles of test as in the following table condition is repeated, The discharge time of the
100th,200th,400th,500th is more than 5 hours. (Ambient temperature is 20±5°C)
The battery shall not leak during the 14 days which it is submitted to the condition
of a temperature of 33±3°C and a relative humidity of 80±5%
6.1 We recommend you to set the cut-off voltage at 1.0V/cell
6.2 If the cut-off voltage is above 1.1V/cell, the battery may be underutilized resulting
insufficient use of the available capacity
6.3 If it is below 1.0V/cell,the battery may have discharge or reverse charge to the cell
The cells shall be delivered in charged condition. Before testing or using, the cell shall be
discharged at 20±5°C at a constant current of 0.2CmA to a final voltage of 1.0V/cell.
7.1 Avoid throwing cells into a fire or attempting to disassemble them.
7.2 Avoid short circuiting the cells.
7.3 Avoid direct solidarity to cells.
7.4 Observe correct polarity when connecting.
7.5 Do not charge with more than our specified current.
7.6 Use cells only within the specified working temperature range.
7.7 Store cells in dry and cool place.
