So I already bought a battery and it's working, although for what I paid
for the battery I feel like I should have just bought a UPS.
For future reference, what's the magic decoder ring to Eaton's product
lines? Really why I want to know is at a minimum next time I buy a UPS
I would like it to be minimum line-interactive but true sine wave;
preferred would be true-online... e.g. equivalent to APC's "SmartUPS" line.
Worst part is, I have a true-online APC sitting in my office at work
leftover from a job (customer said "don't install it, our power here is
the cleanest around" - idiot) but damn ethics won't let me just take it

Thanks, that is helpful.
The more I think about it the more I think that I may still be
shopping for a new UPS in the vague future, because I'm hopfully going
to be looking for a new house soon. If it ends up set up like my
friend's place I would actually need three units and I currently only
have two. The Eaton line does appear to be quite a bit less expensive
than comparable APC stuff and if it's better quality so much the
better. My only experience with them is ordering some large power
conditioners that were spec'd for a job at work... engineer spec'd a
part number, I ordered it. They worked fine, although they were
The reason I could see myself needing three UPS's would be as follows:
1) first one, for cable modem and switch in basement.
2) second one, for wireless access point, located somewhere centrally
in house for best coverage.
3) third one, at big mother PC set up in home office (which may or may
not be at same location as 2)
the reason I didn't need this at my old place was that there was no
"structured wiring" panel or Ethernet wiring run inside the walls, so
I didn't have 1) above. I used the built in switch in my wireless
router to provide a drop to the "office" which was actually in the
basement and directly below the living room, where the wireless router
was located. So, only two UPSs.
Anything "powerware" is decent quality. If it is the big "powerware
prestige" 2000, that is a 2kva dual conversion unit (replaced by the
9000 series) and DEFINITELY worth replacing batteries.
If it is a 2000EX (with the battery plug on the back - extended run -
capable of being connected to an extended battery packor DC Generator)
you have a real gem.
Real HEAVY sucker too!!.
It will take 4 or 5 12 volt batteries if it is that particular unit.
If it is light enough you can throw it across the room, might not be
worth puting much into it, as it is just a simple standby unit - but I
suspect it is the heavy on-line unit from your description (roughly
That's the only place I know that'll sell retail... well I think
there's a Batteries Plus around somewhere but their prices even listed
online are silly... just bought a friend some batteries for her UPS

way more expensive than BW's online price, but where else was I going

Actually as best I can figure, the one that just died lasted *at
least* 7 years. Of course, I had to disassemble the case to get it
out, it was swelled in every dimension. woopsie.
I know this because I've been working at my current job for almost six
now, and I got the UPS from the trash at my *previous* job. Only time
I replaced the battery was immediately after picking it out of the
trash. I pulled a batt. off the shelf in the warehouse and fired it
up to test it, it worked, I told my boss what I did and asked him if
he really meant to put it in the trash, he told me to keep it as he'd
already ordered a replacement. Then IIRC I went to the counter sales
guy, told him I'd taken a battery for personal use, asked him for an
invoice, and he told me to not bother him with petty BS like that.
That place was a LOT more laid back than where I work now :/ (but the
pay was a lot worse...)
I thought that's what he said the prior battery did.
Yeah, it's two paragraphs down.
I don't keep track, but still I think I got 7 years once. Then I
broke out the plastic ridges in the case and put in a battery that was
twice as big. The whole thing failed a few years after that, and I've
wondered if putting in a bigger battery caused that. ??
The simple answer here is to assess the quality of the current UPS and
compare the cost of new batteries to the cost of a new UPS of comparable
I have the same situation here, where the UPS that supports my garage
server rack is an old but high quality Best Fortress 1420 (the good
version with 4 digit display). This UPS is at least 14 years old and
it's original batteries are finally failing. It uses two 17ah gel cells
and clearly the cost of those new batteries is much lower than the cost
of a comparable new UPS.
In my office I have a cheap little Tripp-Lite branded POS UPS that cost
<$100 new. The status display on the thing died in the first year of
use, though the UPS function still works properly. Clearly when the
battery in that UPS goes it will make more sense to buy a complete new
unit rather than replace just the battery.
Yes, I think you understood my question correctly. But I really don't
have any feel for the quality of my old UPS - it's a Back-UPS 650 IIRC
- vs. anything that I could buy new for a reasonable price.
However, I suspect that I am likely going to try a new battery in it
anyway because I'm a cheap ba$tard, unless someone can recommend a
new, amazingly good product that is available for, say, $300 or less.
Why spend $40 when you can buy them for $10 "all day"????
Why do you need a 3/4 KW ups for a wireless router? If you catch 'em on
you can buy a perfectly adequate ups for about the cost of a battery alone.
It can vary considerably, but statistically, almost ALL power disruptions
last less than a few cycles. If the power is out for more than a minute,
it'll probably stay out longer than most consumer UPS's can handle.
Your options are like comparing apples to oranges. YOU have to decide
whether you want apples or oranges.
If it were me, I'd plug the router into the ups that serves the PC and
be done with it.
