I would second this and go further. I spent four years working in the Bahamas where the power reliability is awful, to be charitable. Power cuts averaged about two per month. Some of it just the usual problems of living in an area with a small grid and lots of lightning storms, some of it due to poor maintenance at the electric company. The batteries in an UPS are generally rated for 3-5 years, so: 1) Plan and budget for replacing them in 3 years, including proper recycling. 2) Put a label on the UPS with the date on which the battery was last replaced, and also when it was last inspected. This will save you a lot of grief. --Paul smime.p7s Description: S/MIME cryptographic signature

Thanks for your hints, Stuart. I hope to get one OpenUPS soon and give it a try.

OpenUPS is perfect for this. Or there are cheap chinese boxes that work with 18650 batteries and are meant for this sort of use too (but no monitoring with those like you get with OpenUPS).
Re: Cheaper alternatives for APC UPS
Thank you for all your comprehensive technical references. I just wanted to know if there is any way to save some money buying other brands than APC. After reading your posts I will definitely stay with APC. Salicru, OpenUPS - I have never heard about these brands/solutions. Thanks. > I am not sure about "supported", I wanted to say that you can manage it smoothly using OpenBSD. BTW, do you have any experience with 12V DC small UPS that can be smoothly use with routers only (PCEngines/Soekris). I am looking for an "out of the box" small, silent and low power consumption device that can shutdown my home OpenBSD router when the power is loss. I would like not to use 230V device fot that purpose, which consumes more power when compare to 12V devices.

The home models use a third party protocol supported by one of our ports (I don't remember the names). The professional product lines have support for USB HID. I've used a couple of basic models. The batteries lasted for 3 years and I never had a leak. The windows software is the biggest crap ever done. Use a third party application. -- Juan Francisco Cantero Hurtado http://juanfra.info
Re: Cheaper alternatives for APC UPS
Hello, I have been using OpenUPS for my rack for at least 3 years without a single problem powering server + switch + media converter with 12VDC. This is a DC-DC UPS meaning that it does not replicate a UPS that you simply plug in and it works. The reasons for me using OpenUPS are: -An open system, you chose all aspects of your system! -I can add as many batteries as I want. The OpenUPS is a 10A@12V device, but to it I have 80Ah 12V batteries connected meaning that even at 10A load I get about 7 hours of uptime, in reality I get about 30 hours after power out. -Efficient! Your computer consumes DC, your battery stores DC. Why convert to AC in between? -Programmable (through a windows application) for different battery charging modes meaning that you are even free to chose battery size, battery chemistry, fast and damaging charging or slow and healthy etc. For this you need a source of 12V and a supply for your computer from 12V - which my supermicro board already has built in. dmesg gives me the following: upd0 at uhidev2 and dotbit$ sysctl hw.sensors.upd0 hw.sensors.upd0.indicator0=Off (BatteryPresent), OK hw.sensors.upd0.indicator1=On (Charging), OK hw.sensors.upd0.indicator2=Off (Discharging), OK hw.sensors.upd0.indicator3=Off (NeedReplacement), OK hw.sensors.upd0.indicator4=Off (ShutdownImminent), OK hw.sensors.upd0.indicator5=On (ACPresent), OK hw.sensors.upd0.indicator6=Off (Overload), OK See: http://www.mini-box.com/OpenUPS?sc=8=981 Hope this helps!

Re: Cheaper alternatives for APC UPS
This isn't what you want to hear, but all the alternatives to APC I'd be happy to use are more expensive. I've used cheaper alternatives in the past and they don't put out a decent sine wave or cope with dirty power from a generator. Minimum of SmartUPS, and nothing less. There's a load of second hand ones on ebay for a more reasonable price. PK

I am not sure about "supported", but for a while I used Fideltronik
and was satisfied (battery failed after some years of good job). Alas,
it gave approximated sinus, and I want true one nowadays. The only
choice available in the limits of my budget is either used APC or
another brand, new European-by-the-name-seemingly. I used a second
hand APC (1000-something, blinking leds model), after some years
batteries died and I decided to try this other option. It worked fine
for two years, then died. Upon inspection I found that certain part
inside looked like burned, with ash on it (possibly burned
plastic). Also, I cannot bet on it because I stuffed the battery
somewhere ("hey I can reuse that for a hobby!") and am not sure where
it is, but I would say there was single 6v unit inside. As far as I
can tell, the ups never reported more than 50% load, so I do not think I
overworked it.
Anyway, I could easily lift its battery on two fingers, maybe
three. In both APCs (I am on another second hand now, again
1000-something but now with lcd display) there are two 12v batts (I
think) and I would rather not want to lift any of them other than on
full arm. The first second-hand will probably be inspected and turned
into spare unit, because the current one will finish itself too, one
day. But the batts can be replaced in both models.

Hi Radek I had a lot of problems such as overheating, and much shorter lifespan of batteries with cheaper brands.
