low Runtime Remaining Smart-UPS RT 8000 XL

[Anonymous user]

Hi There

We have a low run time remaining of  11min

Here are the other value given :

The load of the server isn't much about 16% but I only have   11  remaining which I think should be a lot more then that ??

I did a calibration test but still the remaining minutes are still the same can you help?

thanks

Hello Sir,

Good day to you. There are few reason why you will encounter such problem. You can reference to this article:

thanks for the reply

so you say if

Light load accuracy- The estimated runtime values quoted on the web are based on an algorithm which tends to be less accurate for light loads and long runtime applications.

my load is too loght  the ups will be less accurate ? so i should put some more  load to it ??

That would be one thing we you can try. Also have you ever replaced the batteries of the UPS? If you did, when was the last time?

I just try to add some more loads but the minutes are decreasing to 6   min !!!

I change the battery in 2012-06-01

Did you perform a runtime calibration on the new battery?

After the battery has charged for 8 hours, I would unplug the UPS and see how long it runs your load. We'll call that "actual runtime." Then let it recharge and compare the actual runtime with the new estimate. I would also try comparing with the advertised runtime for the SRT8000XL, but I don't see the specs on APC's website anymore.

yes i did full calibration and self test with the new battery  still with the load at 20% i have 5 min left

Alright. It'll be interesting to see how that 5 minute estimate compares to the actual runtime.

You might also want to inspect the battery for any serial numbers that could indicate date of manufacture.

Also, if the replacement is a genuine APC battery, you could contact APC's tech support here:
