Good news / please read, Re: museum network rack
The good news about buying a new unit, is new batteries. Any donated unit would have old or no batteries, you'd have to buy new ones for use. Typically gel-cell batteries are tens of dollars each plus tens of dollars shipping, bigger cost more. Your unit (reading the manual) probably uses three 12V 7Ah batteries; those are common enough, probably about $100 to replace. Probably replace every two-three years depending on how many times they get discharged (extended power failures). When they get cooked, they swell up, it's visible. Good luck!

My APC 1500va 2u unit, I just buy new batteries at $20/ea, 4 total. Used units are everywhere and near free. One popped last year and off-gassed so I just unplugged the battery sled and haven't bothered replacing them yet. I got the unit cheap somewhere. A set of batteries lasts 4 years I'd guess. I used to have a 36kva unit. The batteries would have cost $6000 to replace when it hit the end of the line. That system was impressive but a beast. 300 amps, 3 phase 208 out.
Not sure of the status of this project... I've worked with these guys http://www.refurbups.com/ for both rebuilt units and new batteries. They're located just off the NY Thruway west of the Tappan Zee, so you might be able to save the cost of shipping if someone can pick up the UPS and drive it down to IA. My opinions carry less weight than Herb's so this is my $9.95 worth. :-) Jim On Fri, 29 Jun 2018, Ethan O'Toole via vcf-midatlantic wrote:
