speaking of UPS's...

I -almost- ordered $300 worth of UPS replacement batteries today, but on 
a hunch, I swapped electronic modules with a twin UPS (the ERM is 
hotswappable on these 2U 3000VA units), and lo and behold, its the ERM 
thats faulty, not the battery pack.   found a fleabay ERM for $250  (OEM 
wants $1000).    I have 3 of them, all about 5 years old, with 3 2U 
expansion battery packs, for a total of 9 battery packs, $2000-3000 to 
replace all of them.
