Cutoff Voltage

A value specified by the manufacturer up to which a rechargeable battery can be discharged without affecting its service life.

If the battery were to be discharged even further (deep discharge), there is a risk of damaging it. Flooded lead-acid accumulators are very sensitive to deep discharge.
