Humidity
The battery shall not leak during the 14 days which it is submitted to the condition
of a temperature of 33±3ºC and a relative humidity of 80±5

1. OTHERS
   1. We recommend you to set the cut-off voltage at 1.0V/cell
   2. If the cut-off voltage is above 1.1V/cell, the battery may be underutilized  resulting

    insufficient use of the available capacity

1. 1. If it is below 1.0V/cell,the battery may have discharge or reverse charge to the cell
2. PRECAUTION

The cells shall be delivered in charged condition. Before testing or using, the cell shall be
discharged at 20±5ºC at a constant current of 0.2CmA to a final voltage of 1.0V/cell.

Avoid throwing cells into a fire or attempting to disassemble them.
Avoid short circuiting the cells.
Avoid direct solidarity to cells.
Observe correct polarity when connecting.
Do not charge with more than our specified current.
Use cells only within the specified working temperature range.
Store cells in dry and cool place.
