Every time you discharge a battery, even a little bit, it is "damaged" in the form of reduced capacity. Deeper discharges or longer periods without recharging result in more capacity loss.

That day will come a little earlier than if the battery hadn't been discharged so deeply, but you may never even notice the difference.
