Product Specification
7/10
⑶ Temperature 0～40℃ is preferred when charging;
⑷ Charging voltage must be lower than 4.25V.
8.3.2 discharge
⑴ Discharging current must be lower than (or equal to )2C
5
A;
⑵
Temperature 0
～
60
℃
is preferred when discharging;
⑶ Discharging voltage must not be lower than 2.75V.
8.3.3 over-discharge
It should be noted that the cell would be at an over-discharge state by its self-discharge.
In order to prevent over-discharge, the cell shall be charged periodically to keeping voltage
between 3.7-3.9V. Over-discharge may cause loss of cell performance. It should be noted that
the cell would not discharge till voltage lower than 2.75V.
8.4 Storage of polymer lithium-ion batteries
The environment of long-time storage:
Temperature: 20±5℃;
Humidity: 45-85%;
Batteries were 40
～
60% charged.
In case of over-discharge, batteries should be charged for one time every 3 months while
storing. Batteries should be discharged and charged after being stored more than a year in order to
activate it and restore energy. Please charge the battery with constant current 0.5C
5
A for 1 hour so
that it has some storage of charge for properly using.
Charge and discharge afresh to active and renew battery energy after storage above 1
year.
8.5. Transportation of polymer lithium-ion batteries
The batteries should transportation with 10
～
50% charged states.
8.6. Others
Please note cautions below to prevent cells’ leakage, heat generation and explosion.
Prohibition of disassembly cells;
Prohibition of cells immersion into liquid such as water or seawater;
Prohibition of dumping cells into fire;
Prohibition of using damaged cells. The cells with a smell of electrolyte or leakage must
be placed away from fire to avoid firing.
In case of electrolyte leakage contact with skin, eye, physicians shall flush the electrolyte
immediately with fresh water and medical advise is to be sought.
