New UPS not taking my computer load please help

Well I got the same Ups from 2009-14 with original 9Ah battery and one fine day it just gave up. During the time it powers up two general desktop (alternatively) and one Mac Mini 2011and Dsl modem and router and it almost on 24x7. But one fine day last year it suddenly stopped. It can't take anything even a phone. Always overload.

Removed battery and checked - Everything is fine (above 12volt). Tried with new 7Ah exide power safe battery and no go. Finally fed up with all UPS shit - this is my 5th Ups from 2002.

Called up local inverter guy - bought 800 va ups+ inverter for 6k as I remember no battery needed as it already there which is 150 Ah Exide Inva Tubular.

Was worried about crossair vx 550 can able to run on the 800 VA or not but it worked like charm. Vx 550 was the reason bought this APC 1500 vs ups.

Finally realized it is not the VA rating that matters, it is battery Ah rating does the job.

Why should this happen? Pretty annoying.

The battery cannot provide the current. Get them checked under load, how many Amperes they are pushing out. The wattage is a factor of load(resistance), potential difference(voltage), and the current required. Your device load of connected articles is fixed, and you measured the batteries some day back for correct voltage. So, I guess, the current draw is not being fulfilled.

You APC ups batteries were already 9ah and still you tried 7ah for troubleshooting purpose but it was your ups at fault.
And now with 150 Ah Exide Inva Tubular battery your really not have to worry.

Cant go for ups + inverter as its not that die-hard need.
 
One can get a 600VA (invertor come UPS) with 100 AH TUBE battery for almost 10-11k, this will eliminate any need for separate UPS for PC and will give atleast 3-4 hours of backup along with fans/lights etc.. I will never buy a UPS again for my PC. For home uses Invertor(come UPS) is way to go. after 3-4 years just need to replace the battery for almost 6-7k and you are good for another 3-4 years.

I bought a 600 VA APC UPS for 3.2k, it lasted 1.5 years, but once the original battery died, couldn't find the original battery and they were too costly almost 2k online. Exide once didn't last more then 6 months. So got fedup with APC UPS.

Now with 150 AH battery + inverter combo I forget to switch off my PC etc even when power is not there and most of the time I don't even know that if there was a power cut. It can easily last almost 6-7 hours with fans/light etc.

For example below combo can be get in local market for almost 12k. -- with 135AH tube battery. Although I would prefer the Su-Kam Falcon 600 VA + 100AH TUBE battery combo(for low cost purpose).

Pretty cool man.
But how much monetary damages on regular electricity bills??

Its just that today I observed, when pc runs on AC current via UPS, wattage shown in Monitoring tool is 137w or so and as soon as the light goes off and pc starts to run on UPS mode, the wattage keeps increasing from default 137w to hooping around 190w. Now why this happens?

Its calculating power drawn from the battery, and as you know DC needs to be inverted to AC, which has some loss. Its possible that its fairly lossy at low loads.
The other possibility is since this is primarily a UPS, the power metering part would have been designed with a minimal budget and minimal accuracy.

Hmm might be the case. But showing abnormal loads when on ups mode is illogical. Then why on their site they have shown in graph that on so n so load it shall approximately give so much backup time?

Forget time, here the wattage load itself is messing within. So the backup time is bound to decrease.
 
Guys somethings terribly wrong.
Now at power outage in just 5 min, from 100% battery charge it went down to 45% at 181watts constant n showing just
Wtf?

Well it depends how much power cut is there in your area + Plus how many items you are using during power cut.. I guess you will have to add almost 30% extra units to whatever you consume during powercut. I . e. if you use 20 units in a month via invertor, then in actaul electricity bill be there for almost extra 25 units. otherwise if very low power cut then you will get only 40-50 rs of difference in your power bills.
 
Any 9AH battery will give hardly 15 mins battery time with almost 180 watt load, in those APC 600 VA UPS.

Need some clarification on this.

Desktop was idle at both time when on AC and on UPS mode.

Just goto the sensitivity/voltage option, there you can select the min/max range of voltage that you want your UPS to take in. Also when the wattage was increasing did you check the task manager to see if some process was consuming the CPU, thus increasing the power load. You can check this when the mains power is on. Try to load the CPU and see how much change is there in total watts

Get a new UPS - preferably a basic one with just an on/off switch and no complicated monitoring software :D

Man this aint funny. And if you think I'm worrying needless by looking at those software figures then its wrong. Tool is provided to give 99% accuracy and also to rectify if anything is wrong. So the readings are the primary source where we can look upon and refer to.

@Rickyk & @asingh thanks for the recommendations but not looking forward to buy any new product as of now. At least until I troubleshoot this one so as to avoid similar issues with future products.

*****But here are some interesting observations from experiments I conducted today *****

I charged the ups to 100%. (its always 100% though).
Disconnected all attached equipments. And ran my whole pc setup on direct AC power.

Powered on pc and started Powerchute manager. So nothing was attached hence Estimated battery time was showing 737min and gradually settled down to 550mins both at "0" watts of power.

---Then I connected my old 17'in Viewsonic lcd monitor whose max power requirement is 28W.

It showed "0" watts and moved to 8 watts.

---Then alone plugged a 15 watt eveready essential bulb but it was always showing '0' watts.
In ups battery mode as well it showed "0" watts. Estimated battery time was also constant at 550 mins.

---I connected a 230v old local psu and connected 80mm 5 led fans and 1 simple led fan and it came to 17w of drawn power.
But when I put it ups battery mode, it reached to 60watts and stayed there.

---Now plugged in the 230v psu with fans + Viewsonic lcd + new Dell 22in ips monitor and it draws total current between 34-43 watts.

The same on ups battery mode draws max 69 watts and always stays either at 60w or 69w.

---Finally connected my cpu + dell ips monitor, it drew 138w total.
And when on ups mode, it juggles between 190watts-198w and ups battery level comes down instantly to 93% in 18secs from 100%.

And once again when I turned the mains/AC on, the wattage came back to 138w.

** In all above experiments and normally as well, the Estimated battery time value too fluctuates and decreases at alarming rate like 2 mins in 1min of actual clock time.
Eg: Estimated battery time 60mins will deplete in Real-time 30mins or less.

So one cannot be sure that on ups battery mode really you will be getting 30min or any definite backup.
It can be 25 or even 15mins. Lots of variations.


There's some definite ratio and hence the ups draws more current in battery mode. Now 9ah is the standard battery standards set for this and most models but 9ah isnt mfged. anymore by leading battery cos. so we go for 7ah.
So can this Ah thing cause this stuff as well?

I casually visited the exide battery showroom from where I put in new batteries and he said theres nothing to worry as such. When on battery mode the UPS too gets under some power load and also consumes some power and hence the difference in overall power wattage consumption. And when the electricity comes back, it reverts back to its original wattage consumption.

I urge everybody to try similar above experiments and see the outcomes.

^^ For me I can't try now,But I'm sure that my wattage didn't use to shoot up when there was power outage. it would remain in the same range as when the main was on.

Yup coz you UPS is attached to the inverter and big external 100ah battery.

No that was the case before I got the inverter. Once I got the invertor I have stopped using the APC UPS. There is no need of separate UPS as Inverter(most of the inverter models nowdays) themselves act as UPS. My APC UPS is lying in the box somewhere since last a few months.

With Sukam invertor you get a switch to select the mode -
1. W-UPS - in this mode your computer will restart like old inverter used to be.
2. UPS mode- in this mode it will act exactly like your computer UPS. except that it will have big battery and other appliances connected to it.

Also did you check what I asked you - i .e just switch off the main power and monitor the CPU load in task manager when its running on UPS. May be when power goes off, your APC software in trying something funny which is actually increasing the power load.

EDIT: Ok just saw your last post carefully, there is something else going on it seems. as it is happening even where there is no CPU is connected.
