For example, a battery with a nominal capacity of 100 Ah (C 10 capacity for a 10hour discharge), when discharged with a 10 A current (C/10 rate) will take 10 hours to discharge the battery fully. However, if the same battery is discharged with double the current (20 A), due to the internal losses, the discharge time would not be the expected 5 hours, but a shorter time.
