Seattle area battery dealers, DC UPS

Seattle area telecom: Can anyone suggest a battery distributor/warehouse that stocks deep cycle lead acid batteries of the type suitable for a DC UPS? Shipping costs on these are very high so we would prefer to buy from a dealer somewhere along I-5 in the area from Bellingham to Olympia. We're looking for 6V 220aH T105 (golfcart type) and AGM 12V 120aH batteries.

UPS runtime

UPS/Battery backup question - I need a battery backup power source that will last as long as possible. My load is only 30w, so I understand that even a small UPS will power it ok - but I need to maximize the time that the UPS will continue to keep it going. [more inside]

Battery shelves for a huge DC UPS

Battery shelf manufacturers: I need links to manufacturers of steel battery shelves for large DC UPS applications, for use with AGM VRLA lead acid batteries such as 2V 600aH to 1200aH and 6V 220aH to 600aH+ sizes. Batteries will be Rolls or a competitor. The shelves should knock down into something that can be flat packed and reassembled at an installation site. Features for earthquake bracing and shock mounting are also useful. Where do the US RBOCs buy their shelves?

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?

Will this overload my UPS?

I have a 850va 425w UPS battery backup with only 2 outlets. There is a small server, speakers, home theater projecter, lcd monitor, and router connected to a power strip. The power strip and a desktop plug into the UPS. Is this setup safe? I am concerned about short 1-second interruptions caused by bad electrical connections rather than power outages.
