Configuring UPS For Router

This was originally posted on APC forums on 11/10/2014


Hi there,

I have recently just purchased a Back-UPS ES 700G which has 405W.

My main purpose of this UPS was to keep my ADSL Router on 24/7 due to the area I live in, power-cuts at this time of the year can be quite frequent and I'd like to keep my router on 24/7 top prevent my DSLAM in thinking there is a fault when there's a power cut and dropping my connection.

So I have plugged my router in to one of the surge/backup plugs (top row) and when I unplug the UPS from the mains it say i only have 35 mins of battery remaining.

My question is, how do i configure the UPS to read that my Router only uses 9W - so that I get far longer battery life?

Thanks.

I am not sure I understand why connecting another device into it caused it to turn off. I was suggesting attaching a non-critical load to the UPS, at least 35%, and letting it run until it turns off as I described above.

You could put the UPS on battery power for several minutes and see if it recalculates the amount and updates it for you, assuming you're looking at this via PowerChute (or if your UPS has a display). This would ultimately help re-calibrate the value. To do a full blown calibration, you could let the UPS run on battery for a while until it turns off (with any USB cable disconnected). For this to be super successful, I'd put a higher, non critical load on it so it does not take too long and so the load is high enough for the UPS to use. Usually we say at least 35% and make sure the load does not fluctuate more than 5% either way.

I apologize if I was not clear on that as my intent was to just suggest a calibration with a higher load because I don't know if it will work with such a low load. If that does not work after you put a larger load on it and disconnect the USB cable and allow it to run, turn off, and charge up, then it might be a limitation of the UPS at this low of a load. Though, I have no reason to believe the UPS would not run on battery for the proper amount of runtime that it should with that load %. As I mentioned, the reported runtime is a really good estimate originally so the only action is to try a calibration.

If that is the case, where the calibration won't work, and it is unacceptable, I'd suggest contacting your local support for additional options to manage this issue.

Can you provide the exact SKU of the UPS from the back or bottom? I just want to make sure if I need to look up further information, we know the specific model.

In general, the amount of runtime many UPS model of this type report when it is online is a really good estimate. As the UPS operates on battery with its load, it re-calibrates and constantly updates that value to reflect what it knows it has left based on that load, capacity, health, etc. If the UPS has not experienced a power outage or something that caused it to go to battery power, then it might not be a really good estimate, especially if its brand new. You could put the UPS on battery power for several minutes and see if it recalculates the amount and updates it for you, assuming you're looking at this via PowerChute (or if your UPS has a display). This would ultimately help re-calibrate the value. To do a full blown calibration, you could let the UPS run on battery for a while until it turns off (with any USB cable disconnected).

Hi - no problem. Thanks for grabbing that information.

What I said will apply beyond the fact that your UPS does not have a display. Any data would be seen via PowerChute.


Let me know if you had any questions/concerns regarding what I mentioned.

Hi there,

I had my UPS on battery for a good 17 mins and then i re-connected to the mains to charge but its still showing only 40 mins battery time.

Do i need to set the threshold and if so, could you guide me please?

You might want to try it with a higher load, at least the 30-35% I suggested. There is no setting or threshold you can adjust to change the reported runtime unfortunately.

I just plug another device into it & it turned off, which means my net dropped & it wouldn't turn back on for about 5 mins - this hasn't helped and still reports only 40 mins backup time.

So have I not only just had my net drop in sync i am no further in increasing the time on the UPS
