[tech] Auction TOMORROW for UPS

[Mitch Kelly (UCC)]

Chances are if they have been sitting for that long the batters are
sulphated and will be useless.

Im 50/50 on getting them as the batteries will cost a fortune to replace.

Shelf life of a SLA that is sitting not being used/charged is only about 9
months at absolute most.

I checked them out this arvo and they are new in box. As Harry suggested, 
they are several years old. Each unit has a matching expansion battery 
shelf (as separate lots) which boosts the running time at max load from 6 
minutes to 29 minutes. I think that would be worth getting if we can.

I wasn't able to take the covers off them to see the exact battery model, 
but the manual says they take 6 standard 12V 9Ah CSB batteries. Judging 
from the cost of the last set of batteries we bought for the SAN UPS, I 
think a new set would cost ~$250.

The 'technician' at Ross's estimates the UPS's will go for ~$200 each. I 
think they will go for less. Committee: can I please have approval to bid 
up to a total of $400 for a controller and expansion shelf?
