How critical is the 2.5V cut-off voltage for Li-Ion battery life?

Webpicked up a Low Voltage Cutoff protector for my lithium-ion battery and I was wondering what is the calculation for the "limit" to set the cut off at (i'm guessing 12v, 18v, 20v and 24v all have different cutoff rates). In batteries, the cut-off (final) voltage is the prescribed lower-limit voltage at which battery discharge is considered complete. The cut-off voltage is usually chosen so that the maximum useful capacity of the battery is achieved. The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used.
