constant current 0.5C discharge to 3.0V, rest 10min.
Repeat above steps till continuously discharging capacity
higher than 80% of the initial capacities of the cells.
≥300 times
4.3 Capability
of keeping
electricity
20±5ºC, After standard charging, rest the battery 28days,
discharging at 0.2C to voltage 3.0V, recording the
discharging time.
≥240min
5. Environment performance
NO. Item Test Methods and Condition Criteria
5.1 Discharge at high
temperature
After standard charging, rest the cells 4h at 60±2ºC,
then discharging at 1C to voltage 3.0V, recording the
discharging time.
≥54min
5.2 Discharge at low

≥210min
5.3 Thermal shock Put the cells in the oven. The temperature of the oven
is to be raised at 5±2ºC per minute to a temperature of
130±2ºC and remains 30 minutes.
No re
or explosion
6. Safe characteristic
NO. Item Test Methods and Condition Criteria
6.1 Over charge
testing
At 20±5ºC, charging cells with constant current 2C to
voltage 5.0V, Stop test till cells temperature 10ºC lower
than max temperature.
No re
or explosion
6.2 Over discharge
testing
At 20±5ºC, According to the requirements of standard
charge, the cells will be discharge to cut-off voltage,
then The discharged cell is then subjected to a forced
discharge at constant current 1C to -4.2V. The total
duration for the forced discharge testing is 90 min.
No re
or explosion
6.3 Short-circuit

surface temperature declines by 20% of the maximum
temperature rise, whichever is the sooner.
No re
or explosion
Note: Above testing of safe characteristic must be with protective equipment.

7. 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 re.
• 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.
• Battery must be charged in appropriate charger only.
• Never use a modied or damaged charger.
• Do not leave battery in charger over 24 hours.
• Store the battery in a cool, dry and well-ventilated area.
• Regulations vary for different countries. Dispose of in accordance with local regulations.
8. Battery operation instruction
8.1 Charging
Charging current: Cannot surpass the biggest charging current which in this specication book stipulated.
Charging voltage: Does not have to surpass the highest amount which in this specication book stipulated to
decide the voltage.
Charge temperature: The battery must carry on the charge in the ambient temperature scope which this
specication book stipulated.
Uses the constant electric current and the constant voltage way charge, the prohibition reverse charges. If the
battery positive electrode and the cathode meet instead, can damage the battery.
8.2 Discharging current
The discharging current does not have to surpass this specication book stipulation the biggest discharging
current, the oversized electric current electric discharge can cause the battery capacity play to reduce and to
cause the battery heat.
8.3 Discharge temperature
The battery discharge must carry on in the ambient temperature scope which this specication book stipulated.
8.4 Over-discharges
After the short time excessively discharges charges immediately cannot affect the use, but the long time
excessively discharges can cause the battery the performance, battery function losing. The battery long-term
has not used, has the possibility to be able to be at because of its automatic ashover characteristic certain
excessively discharges the condition, for prevented excessively discharges the occurrence, the battery should
maintain the certain electric quantity.
8.5 Storing the batteries
The battery should store in the product specication book stipulation temperature range. If has surpasses
above for six months the long time storage, suggested you should carry on additional charge to the battery.

9. Warranty
The warranty is specied in our warranties section of Terms of Sales. If the product is to be stored for more than
three months it is necessary to perform the appropriate maintenance to ensure the good condition of the batteries.
Consult our annex to the Terms of Sales on the recommended maintenance.
10. Other the chemical reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long
period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient
temperature, etc. are not maintained within the specied ranges the life expectancy of the battery may be shortened
or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a
charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
11. Note
Any other items which are not covered in this specication shall be agreed by both parties.
