Test method |
| 1 |
Overcharge performance |
No explosion, no fire |
battery in 1C5A Constant current and constant voltage charging to 4.8V and keep 48H |
| 2 |
Over-discharge performance |
No fire, no explosion |
After the battery is charged to the standard, the 0.2C5A Discharge to the termination voltage, and then use30 Ω The resistor connects the positive and negative terminals of the battery and leaves it aside24 sky. |
| 3 |
Short circuit performance |
No explosion, no fire |
After standard charging, the resistance is not greater than0.1 Ω The copper wires connect the positive and negative electrodes to the battery body where the temperature is close to room temperature. |
| 4 |
Heavy object impact performance |
No explosion, no fire |
After standard charging of the battery, place it on a flat surface with a diameter of 15.8mm The rod is placed in the middle of the height direction of the battery, so that the weight 9.1kg of heavy objects from 610mm Drop freely to the impact table. |
| 5 |
Thermal shock safety performance |
No fire, no explosion |
After standard charging of the battery, place it in a hot box at a temperature of(5 ℃±2 ℃)/ min rate rises to130 ℃±2 ℃ and keep warm 10Min . |
Strict process control:
Various battery certifications complete
Notice to buyers:
Directly supplied from the factory. Since each battery requires different cable lengths and protective board parameters, please consult customer service before taking a photo to confirm the specific parameters before taking a photo.
