Cell Safety Testing

1.External short circuit

Testing Instruction:Fully charged batteries are stored in an ambient temperature of 20℃±5℃,battery is then short-circuited by connecting the positive and negative terminals with a total external resistance of less than 5mΩ .The batteries remain on test for 10Min.

2.Free fall

Testing Instruction:Each fully charged battery is dropped three times from a height of 1.0 m onto a concrete floor.The batteries are dropped so as to obtain impacts in random orientations.

3.Mechanical shock

Testing Instruction:The fully charged battery is secured to the testing machine by means of a rigid mount which will support all mounting surfaces of the battery.The battery is subjected to a total of three shocks of equal magnitude.The shocks are applied in each of three mutually perpendicular directions.At least one of them shall be perpendicular to a flat face. For each shock the battery is accelerated in such a manner that during the initial milliseconds the minimum average acceleration is 75 gn.The peak acceleration shall be between 125 gn and 175 gn. Batteries are tested in an ambient temperature of 20 °C ± 5 °C.

4.Heating test

Testing Instruction:Place the fully charged monomer battery in an aircirculating oven where the oven temperature rises from 5 °C/min ± 2 °C/min to 130°C± 2°C, where it remains for 10min.

5.Crushing of cells

Testing Instruction:Put the fully charged single cell in the condition of 20℃ ±5℃. Extrusion direction: Pressure on the direction of perpendicular to the battery plate Extrusion size: not less than 20 c㎡; Extrusion Level: until the battery case rupture or the internal circuit (battery voltage is 0V).

6.Overcharge

Testing Instruction:The cell is discharged with 0.5 C to the end-of-discharge voltage, then charged from a power supply of 5 V,at the charging current 0.3 C for 12,5 h.

7.Overdischarge

Testing Instruction:20 ℃ ± 5 ℃ ,0.3C discharge.( (If has electronic protection circuits, the electronic discharge protection circuit should be temporarily removed), tests ends until a single battery voltage reaches 0V.

8.Acupuncture

Testing Instruction:Prong it by direction of perpendicular to the battery, with φ 3mm-φ 8mm high thermal resistant needle by the speed of 10mm/s-40mm/s.(the steel needle stay on the battery).

(The above test results meet the performance requirements:No fire , No explosion)

A:Storage Conditions
If the product is stored for a long time, please charge the battery pack to about 60% of the electricity, put it in the dry and ventilated place, and charge the charger for 3 hours (10A charge) every 3 months.Batteries and chargers should be stored in clean, dry and ventilated places. Avoid contact with corrosive substances, away from fire sources and heat sources.
 
B:Battery Handling Precautions
1.Do not put the battery pack into the water or soak it!
2.It is forbidden to charge battery pack under fire source or extremely hot condition. Do not use or store batteries near heat sources (such as fire or heater). If the battery leaks or smells, it should be removed immediately from the open flame. The first time you use batteries, you need to charge the battery and use it again!
3.Do not reverse the positive and negative!
4.Do not put the battery pack into the fire or heat the battery pack!
5.No wires or other metal objects are allowed to short circuit the positive and negative poles of the battery pack!
6.Do not pierce the battery pack housing with nails or other sharp objects, and do not hammer or pedal the battery pack!
7.It is forbidden to pierce the battery housing with nails or other sharp objects. No hammer or pedal batteries are allowed!
8.It is forbidden to put battery in microwave oven or pressure vessel!
9.If the battery pack is out of smell, heat, deformation, discoloration, or any other abnormal phenomenon, if the battery group is being used or charged, it should be removed from the appliance or charger immediately and stop using it!
10.You cannot use batteries in extremely hot environments, such as in direct sunlight or hot days. Otherwise,the battery pack will overheat, which will affect the performance and shorten the battery life!
11.If the electrolyte drops into the eyes after the battery is leaking, do not rub it. Rinse immediately with water and seek medical help immediately. If you don't handle it in time, your eyes will be hurt!
12.If the electrolyte drops into the eyes after the battery is leaking, do not rub it. Rinse immediately with water and seek medical help immediately. If you don't handle it in time, your eyes will be hurt!
13.If the battery pack has abnormal smell or abnormal sound during charging, stop charging immediately.
14.If the battery has abnormal smell and abnormal sound during discharge, stop discharging immediately.
15.If the above phenomenon occurs, please contact the manufacturer, do not disassemble privately.
