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. |
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 80%.
1 month-20°C ~ 60 °C
2 months -20°C ~ 40 °C
3 months-20℃~ 25 °C
Appearance
There shall be no such defect as deep scratch, flaw, crack, rust, leakage, which may adversely affect commercial value of the cell.
Package
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 information.
Warnings and Cautions in Using the Long life rechargeable lithium 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.
● Do not remove the outer sleeve from a battery pack nor cut into its housing.
● 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.
Ship
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.
