to for 2.5
hours, rest 5 hours, measured at
1000Hz
≤1500mΩ
6. Cycle life
By IEC standard:

After 500 cycles
7. Self-Discharge
The charged battery is stored for 28
days at 20±5. And the discharge
time is measured at Nominal
discharge
≥180minutes
8. High Temperature Test
Store at 405060 for 2 hours
then Charge/Discharge
No leakage
9. Low Temperature Test
Store at 0 for 2 hours then
charge/discharge
No leakage
10. Short Circuit Test
Short circuit after fully charge
No explode
11. Drop Test
Free fall on the concrete from 1
meter using to 3 axis after fully
charged
No Break
No short-circuit
