You obviously don't have much experience with them. Check out the oddysey technical manual. They do into great detail about all the testing done, life cycle vs DOD, mil spec requirements, etc. One such test involves draining to 0%, placing a resistor across the terminals for 30 days, and then charging with a fixed voltage for 24 hours. IIRC, capacity was about 75% of original and improved over the next few cycles.
Pretty hard to kill....
