INR18650-3000mAh Li-ion Rechargeable cylindrical battery

INR18650-3000mAh Li-ion Rechargeable cylindrical battery,18650 battery,High
security lithium ion battery,power tool lithium ion battery supplier

Safety  Characteristic of car 18650 battery

NO. Item Standard Test Method
1 Overcharge No fire、No explosion After standard charge, rest
for 10mins; then charge at constant current of 3C to 10V.(or charge at 3C
2 Forced discharge No fire、No explosion The battery to be
discharged with standard discharging condition, Inverse charge current =1C;
time: ≥90mins

               3 Short Circuit test No fireNo explosion The
battery to be fully charged with standard charging condition, and short the
positive and negative terminals with wire resistance ≤50mΩ.Tests are to be
conducted at 23℃±3℃  and at 55℃ ±5℃, keep 24h or casetemperature
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 initial3ms, 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
to130°C±2°C,and maintain for 10mins.
7 TemperatureCycling 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 within30 minutes and maintaining this temperature for 6
hours. c) Repeating the sequence for a further 9 cycles. d) Afterthe 10th
cycle, storing the batteries for 24 hours prior to examination.

Environment Adaptation Performance for 18650 lithium ion battery supplier

NO Item Standard Test Method
1 Altitude/Low pressure simulation test no leakage, no fire, no
explosion The full charged cells are to be stored for 6h at an vaccum
environment with pressure of less than 11.6kPa and atemperature of 23℃±3℃.
2 Free drop test no fire, no explosion The fully charged battery
drops on the concrete ground from height(1m),total 3 times,to obtain the shock
of random directions.
3 Vibration test No remarkable damage、No smoking 、No explosion
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 1.52mm. The
cell shall be vibrated for 90 minutes per axis of x, y axes

Storage Temperature for Shipping

If the cell is kept as ex-factory status (50% of charge), the 0.2C recoverable
capacity rate is more than 90%.
1 month          -20°C ~ 60 °C
2 months-20°C ~ 40 °C
3 months-20℃~ 25 °C


There shall be no such defect as deep scratch, flaw, crack, rust, leakage,
which may adversely affect commercial value of the cell.

The cells are packed with JIANGSU SUNPOWER CO.,LTD. standard carton box, which
hold four inner boxes. There are 100pcs 18650 cells per inner box. And the
inner box and outer box identifies battery capacity, voltage and impedance

Warranty Period & Product Liability for High security lithium ion battery

Warranty period of this product is 12 months from manufacturing code. JIANGSU
SUNPOWER CO., LTD. is not responsible for the troubles caused by mishandling
of the battery which is against the instructions in this specification.
Warnings and Cautions in Using the Battery
To prevent a possibility of the battery from leaking, heating or explosion
please observe the following precautions:
● When using a new battery for the first time or after long term storage,
please use the battery charger specifically for that purpose fully charge the
battery before use.
● Do not disassemble or open, crush, bend or deform, puncture, or shred;
● Do not modify or remanufacture, attempt to insert foreign objects into the
battery, immerse or expose to water or other liquids such as water, seawater,
drinks such as soft drinks, juices, coffee or others, or expose to fire,
explosion, or other hazard.
● Do not short circuit a battery or allow metallic or conductive objects to
contact the battery terminals.
● Avoid dropping the phone or battery. If the phone or battery is dropped,
especially on a hard surface, and the user suspects damage, take it to a
service center for inspection.
● The battery replacement shall be done only by either cells supplier or
device supplier and never be done by the user.
● Replace the battery only with another battery that has been qualified with
the system per standard. Use of an unqualified battery may present a risk of
fire, explosion, leakage, or other hazard.
● Don’t keep a battery at rest for a long time (over 6 months). Safety
accident may happen when recharging battery which has a rest for a long time.
● In the event of a battery leak, do not allow the liquid to come in contact
with the skin or eyes. If contact has been made, wash the affected area with
large amounts of water and seek medical advice.
● Battery usage by children should be supervised. Seek medical advice
immediately if a battery has been swallowed
● Never disassemble cells. The disassembling may generate internal short
circuit in the cell, which may cause firing or other problems.
● Never incinerate nor dispose the cells in fire. These may cause firing of
the cells, which is very dangerous and is prohibited.
● When use the battery , must to ensure the charge and discharge voltage of
the battery is between 2.75V to 4.2V.
● Do not remove the outer sleeve from a battery pack nor cut into its
● Do not mix our batteries with other battery brands or batteries of a
different chemistry such as alkaline and zinc carbon.
● Do not mix new batteries in use with semi-used batteries, over-discharge
may occur.
● Promptly dispose of used batteries in accordance with local regulations.
