Electrical characteristics:
1.Standard Charge:
Charging the cell initially with constant current at 0.5C and then with constant voltage at 4.2V till charge current declines to 0.05C.
2.Cycle Life:
80% or more of 1 st cycle capacity at 0.5C discharge of Operation.
3.Self-discharge:
After the standard charging, storied the cells under the condition as No.6.4 for 28 days, then measured the capacity with 0.5C till 3.0V,Residual capacity>90%.
Mechanical characteristics:
1.Vibration Test:
After standard charging, fixed the cell to vibration table and subjected to vibration cycling that the frequency is to be varied at the rate of 1Hz per minute between 10Hz and 55Hz, the excursion of the vibration is 1.6mm.The cell shall be vibrated for 30 minutes per axis of XYZ axes.(No leakage No fire )
Cautions in use:
To ensure proper use of the battery please read the manual carefully before using it. Handling
· Do not expose to, dispose of the battery in fire.
· Do not put the battery in a charger or equipment with wrong terminals connected.
· Avoid shorting the battery
· Avoid excessive physical shock or vibration.
· Do not disassemble or deform the battery.
· Do not immerse in water.
· Do not use the battery mixed with other different make, type, or model batteries.
· Keep out of the reach of children.
Charge and discharge
· Battery must be charged in appropriate charger only.
· Never use a modified or damaged charger.
· Do not leave battery in charger over 24 hours.
Storage
· Store the battery in a cool, dry and well-ventilated area.
Disposal
· Regulations vary for different countries. Dispose of in accordance with local regulations.
Over-discharging:
It should be noted that the cell would be at over-discharged state by its self-discharge characteristics in case the cell is
not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain between
3.2V and 3.3V.
Over-discharging may causes loss of cell performance, characteristics, or battery functions.
The charger shall be equipped with a device to prevent further discharging exceeding a cut-off voyage specified in the
Product Specification.Also the charger shall be equipped with a device to control the recharging procedures as follows:
The cell battery pack shall start with a low current (0.01C) for 15-30 minutes, i.e.-charging, before rapid charging starts.
The rapid charging shall be started after the (individual) cell voltage has been reached above2.0V within 15-30 minutes
that can be determined with the use of an appropriate timer for pre-charging. In case the (individual) cell voltage does
not rise to 3.0V within the pre-charging time, then the charger shall have functions to stop further charging and display
the cell/pack is at abnormal state.
The soft aluminum packing foil is very easily damaged by sharp edge parts such as Ni-tabs, pins and needles.
· Don't strike battery with any sharp edge parts
· Trim your nail or wear glove before taking battery
· Clean worktable to make sure no any sharp particle
