5 Precautions
5.1 Product End-life Management
The cell life is limited.Customers should establish an effective tracing system to monitor and
record the internal resistance and capacity of each cell during its life.The measurement method
and calculation method of internal resistance and capacity need to be discussed and agreed
between the customer and EVE.When the internal resistance of the cell in use exceeds 150% of the
initial internal resistance,or the capacity is less than 60%of nominal capacity,the cell should not to
be used any more.Violation of this requirement will exempt EVE from its responsibility for
product quality assurance in accordance with the product sales agreement and this
specification,as well as all related liabilities such as loss compensation caused thereby.
5.2 Long-term Storage
After charging,the cell should be used as soon as possible to avoid loss of usable capacity due to
self-discharge.If long-term storage is required,adjust the ell SOC to 30%~40%.The
recommended storage conditions are:0℃~25℃,
relative humidity≤60%.
The state of charge (SOC,capacity state)of the cell should be kept at 15%~40%during
storage.In order to prevent the performance differences after long-term storage(more
than three months),perform a standard charge-discharge cycle every 3 months.It is
recommended that the storage time after receiving the cells should not
exceed half a year to avoid quality problems due to storage overdue.
5.3 Transportation and Handling Requirements
● It is not allowed to ship with inflammable, explosive and corrosive articles in the same
vehicle during transportation,and stacking is prohibited during large package transportation;The
product shall not be exposed to rain,snow and other liquid substances without any
protection,or suffer mechanical damage;
