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
surrounding temperature,then change to charge with constant voltage till the
current less than or equal to0.02C5A.
Electrical Characteristic of e-bike cylindrical power lithium-ion batteries
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.
Safety Characteristic for 18650 power tool lithium ion battery
NO. Item Standard Test Method
1 Overcharge No fire、No explosion After standard charge, rest
for 10mins; then charge at constant current of 3C5A to 10V.(or charge at 3C5A
2 Forced discharge No fire、No explosion The battery to be
discharged with standard discharging condition, Inverse charge current =1C5A；
time: ≥ 90mins
3 Short Circuit test No fire、 No explosion The battery to be
fully charged with standard charging condition, and short the positive and
with wire resistance ≤50mΩ.Tests are to be conducted at 23℃
±3℃ and at 55℃ ±5℃, keep 24h or case temperature decline to 20% of the
max temperature ,test is over.
4 Crush test No fire、No explosion A battery is crushed between
two flat surfaces. The applied force is 13 kN±1kN by hydrocylinder, Once the
maximum pressure has been obtained or voltage decrease to 1/3 of nominal
voltage sharply, then release pressure.
5 Shock test No fire、No explosion The full charged battery is
fixed on shock table, to force a certain shock to three mutual vertical
direction, in initial 3ms, the min. average acceleration is 75gn,the peak
acceleration is between 125gn and 175gn.
6 Heating test
(130°C) No fire、No explosion The cells are fully charged
with standard charging condition, and put into incubator with nature air or
cycled air convected, heat battery by velocity of 5°C ±2°C/min to
130°C±2°C,and maintain for 10mins.
Cycling Test no leakage, no fire, no explosion The fully charged
batteries are placed in a test chamber and subjected to the following cycles:
a) Raising the temperature to 75°C ±2°C within 30 minutes and maintaining
this temperature for 6 hours. b) Reducing the temperature to minus 40°C
±2°C within 30 minutes and maintaining this temperature for 6 hours. c)
Repeating the sequence for a further 9 cycles. d) After the 10th cycle,
storing the batteries for 24 hours prior to examination.
