I'm just dying to know if the last line is 24 hours or what. With this peice of information you could esitmate battery's internal resistance that is generally better correlated with depth of discharge. Then take the battery off the vehicle and lay it on the hot ash, removing the filler/vent covers from the top. At its 12V mark, you can see there is a "tipping point" where the voltage goes from relatively constant to plummeting. How does one determine Lead-Acid battery end-of-life? 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.
