2. Smart Lithium battery 12V 300Ah Electrical Characteristics & Test Condition
@Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.
|1||Min Capacity||≥293Ah||Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the cutoff voltage. you can stop and define the Discharging current*time value (Ah) as battery capacity.|
Cycle life (DOD%100)
Charge / CC(0.33C)/CV(14.6V);
End current : 0.05C;
Rest time : 1h;
Discharge / CC(0.5C);
End voltage : 8.0V;
Repeat above process until discharge capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
|-20℃||≥70%||At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage. Record the ratio between discharging & charging capacity.|
|4||Charge Retention ability||remain capacity≥90%||Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.|
