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 1.0C (-dV:5mV), rest 10 min, charge 1.0A (-dV:5mV) No leakage should

rest 10 min, charge 1.0C (-dV:5mV) occure
