The endurance test is considered complete when two such seccessive cycles give a discharge
duration less than 3 h of any 50th cycle
Safety Performance
Drop test Drop to an concrete floor from a height of 75 cm No machanical and
4 times after fully charge and discharge electrical abnormality
Short-circuit Short-circuit for 2 hours with 0,75qmm wire No explosion
after fully charge and discharge
Overcharge test 1 Charge 0.1C / 16h, charge 0.1C / 48h Discharge time should be
rest 1h, discharge 0.1C to 1.0V > 5h
Overcharge test 2 Charge 1.7A (-dV:5mV), rest 10 min, charge 1.7A No leakage should
(-dV:5mV) rest 10 min, charge 1.7A (-dV:5mV) occure
Reverse charge Charge in reversed polarity 1C / 6 h after fully discharge No explosion
Drop-overcharge Discharge 1.0C to 1.0 V, discharge 0.2C to 1.0 V, drop to No explosion
an concrete floor 3 times, charge 1.0C / 5h
Drop short-circuit Charge 0.1C / 16h, drop to an concrete floor No explosion
3 times, short-circuit for 2 hours with 0,75qmm wire
Fire Stay in fire (250°C) for 15 minutes after No explosion
