You can get away with a ton of stuff in everyday consumer life, but if you are trying to guarantee some performance of your device/product you can't break the rules (unless you're damn good) - this is why all those backup batteries got changed: They would probably still work fine to ~90% of the spec, but when the power goes out on a winters day 3 years from now, and that over-spec discharge event has pushed the batteries too far down the curve, and instead of having the specified 30 minutes in hand to get the power restored, the equipment unexpectedly goes offline 10 minutes early, crashes the network, and puts the whole system down for a day because the restore-from-dead situation is 10x worse than the "controlled shutdown" you're going to look like a right prat, and someone's lawyers are going to be knocking on your door. Changing the battery. However, draining batteries lower than their nominal voltage is destructive and still hurts the battery. Any battery manufacturer worth their salt will be able to tell you this data (and guarantee it), if they can't then don't be using their stuff for ANY critical application. Normally, one would simply use a multimeter to determine the voltage of his or her vehicle battery, but in the event that one does not have one, the above-mentioned will assist a car owner in recognizing that his or her car battery has a low voltage and should be replaced or recharged. 2 offers from 15.71.
