Back-UPS XS 1300 LCD

[Anonymous user]

Hello everyone, I bought that ups nearly 2 months ago and I'm having a little concern.

When I check on the box, it says that with 1 pc and 1 monitor of middle size, it run about 60 minutes.

Now, when I plug 1 computer in it, I get about 50watts of power used in my ups (old computer running linux and nothing powerfull) and get about 88 minutes.

Then, I plug 1 LCD, my computer and my cable modem (even if it already have a battery in it since it's my phone too). When I power everything, I get 226watts (780watts max on that ups), that's a 29% usage.

But then, I check the estimated battery time, 19 minutes... My concern is if at ~30% power usage I get 19 minutes and at ~10% I get 88 minutes, what will it be if I get to 50%... It seems a very big difference in time of battery time and when looking at the graph on the box, 1 computer with 1 monitor (not an lcd) should last over 30 minutes. My lcd use about 30 watts and when closing it, it doesn't even change remaining time on battery.

I think it's pretty low for a 29% usage for a 780w ups, what do you think? Is it reporting false battery time?

Thanks

Judging from our runtime chart linked below, it does appear you should be getting more runtime.

The first thing I would suggest is simply pulling the plug on the unit for a short period and see if the runtime adjusts in the software. It won't read with complete accuracy until it senses the current coming off the battery. If they runtime still doesn't adjust properly, I would suggest doing a manual runtime calibration on the unit. To do this, simply pull the plug and let it run to low battery and gracefully shut down your computer. Then, plug the unit back in and let it charge to full and see if you have any change in your estimated battery time.

I'm gonna try that. Just another thing, you linked me to RS modele and not XS, so I try to find the runtime for my ups. I go at the product review page and click on runtime chart for back-ups xs and it transfer me a on blank page

Ok, I know it took some time before replying and testing but here are the result:

I did 1 power failure about each month in the past months (about 6 times). Each time, I had maximum of 15 minutes of battery backup with a load below 400. (Right now, have a load of 280 W, 15 minutes of battery. When I raise near 300-350, I get less then 10 minutes). Also, I think there's a big problem with my UPS.

I've set it so when there's 6 minutes left on battery, it put my computer on stand by. That work great. When I reach 5 minutes remaining (when load is the same, else, when there's about 2 out of 5 bar on the lcd), the battery backup die instantly (no more power going to my computer/electronic connected on it, lcd display turn off, like there was no more battery). I though this would solve through some monthly full battery cycle but it didn't.

To give you a little more info, in apc powerchute history, for the last week, I had 8 blackouts (had little problem with my electricity but now it's ok). In that one, there is my recent blackout test (one that I test each month with a full battery cycle). The total time on battery for that week is 11 minutes and 15 seconds. How can I have 11 minutes of blackout total in 8 blackouts when I had 12 minutes of battery last manual blackouts and that I had another manual blackout of 5 minutes after (I had to move the ups to another power outlet and had trouble doing so). Yes, my pc was on in both time.

Is my unit defective?

Thanks
