A deeply discharged battery must be disposed of immediately, because in this case the battery can definitely no longer be reactivated. But you can only speak of a real deep discharge when the battery voltage is only approx. 5 - 7 volts or less. If, however, the battery voltage is still somewhere between the actually required nominal voltage and the state of true deep discharge, then there is justifiably still hope.
