Characteristic of High security rechargeable lithium battery
Without special instructions, the following tests should be done under the
condition of : temperature(23℃±3℃), atmospheric pressure (86KPa~106KPa),
relative humidity (45%~85%), and the tests should be done within two weeks
after receiving the products.

the definitions of some nomenclatures of this specification
standard Charge: Charge with current 0.2C5A to limit charge voltage under the
condition of23℃±3℃
surrounding temperature,then change to charge with constant voltage till the
current less than or equal to0.02C5A.

Electrical Characteristic for Long life lithium ion battery

NO. Item Standard Test Method
1 Discharge rate capabilities A)1 C5A ≥100% B)10 C5A ≥95% C)15
C5A ≥90% Standard charged under the condition of normal atmospheric
pressure and the environmental temperature of 23℃±3℃ and45%~85%RH, then
rest for 30mins and discharge at1C5A、5 C5A、10 C5A to the discharge cut-off
voltage respectively. Charge/discharge cycle can be conducted for 3times
before meeting the Standards(the same below)
2 capacity retention and recovery Residualcapacity≥94%
Recoverablecapacity≥*98% Standard charged under the condition of normal
atmospheric pressure and the environmental temperature of 23℃±3℃, Stored
for 28 days, then discharge at 0.2 C5A to 2.75Vmeasuring residual capacity;
Then standard charge/discharge measure recoverable capacity.
3 Low Temperature Performance discharge capacity≥85% rated
capacityno distortion and no rupture The cell shall be charged in
accordance with the standard charge. Then stored in the temperature of -10℃
±1℃ for4h, Discharge at the constant current of 0.2C5A down to the end-of-
discharge voltage 2.75V.
4 Cycle Life ≥300cycles Charge: The cell shall be charged in
accordance with RapidCharge condition. rest for 10mins.Discharge: 10C5A
discharge to 2.75V, one cycle is finished, then rest for 30mins. Then repeat
above steps, when capacity is less than 80% of initial capacity, the battery
life is over.

The cells might be damaged during shipping by shock. If any abnormal features
of the cells are found such as deformation of the cell package, smelling of an
electrolyte, an electrolyte leakage and others, the cells shall never be used
any more. The Cells with a smell of the electrolyte or a leakage shall be
placed away from fire to avoid firing.
The cell shall be stored at the environmental condition of -20℃ - 45℃ and
65%±20% RH. The voltage for long time storage shall be 3.6V-3.9V range. If
the cell has to be storied for a long time (Over 3 months), the environmental
condition should be: Temperature: 23℃±3℃ Humidity: 65%±20%RH; please
activate the battery once every 3 months according to the following method:
Charge with current 0.2C5A until the voltage achieve to 4.0V.
