| Off-load
voltage |
Using multimeter(accuracy≥0.25%)internal resistance≥1MΩ |
≥3.20V |
|
| Instantaneous
Short-circuit current |
Time of short-circuit should be less than 0.5
Sencond and avoid repeated test within half An hour |
≥350mA |
|
| Appearance | Eyeballing | Bright ,clen,no rust,no leakage,And no flaw | |
|
Capacity |
Continuously discharge for 8 hour with load
3 kΩ,temperature at 20-25℃,humidity at 65 ±20% till 2.0v end-voltage(for fresh battery only:within 3 months) |
≥478h |
|
|
Vibration test |
Put battery on the platform of the vibrations
Machine,start the machine and adjust the Frequency form 10 times per minute to 15 Times per minute.keep it running for an hour |
Characteristics keep stability |
|
| Leakage at
hight temperature |
Stored under temperature(45℃)for 30 days |
Leakage rate≤0.5% |
|
| Over
Discharge Test |
After 2.0v end-voltage, continuously discharged for 5 hours |
No leakage allowed |
