UPS and battery reference on the large scale

I would like to learn more about large-scale UPS systems, particularly the battery strings used in traditional RBOC/Telco applications. These are the sort of beasts that use huge strings of 6V 220aH deep cycle batteries, or even large numbers of 2V 400aH batteries on very strong earthquake-resistant shelving wired up to create a 48V mega-battery. Can anyone point me to the most definitive reference materials on the subject?
