UPS backup has been reduced dramatically...help anyone?

Okay, inverter (homage axiom 1202) and battery (sacred sun 150ah) bought & set up in april 2014. It used to give me backup for up to 6 hours for load ranging 150 to 300 watts.

10 days earlier it lasted for 3 hours under 150 watts load but from yesterday evening, inverter starts to beep just after 40 minutes and shuts down 5 minutes after that. Since summer is over, the load is always under 200 watts although I suspect the inverter is not showing the load accurately...

Now I am not sure & nor have the proper understanding/tools to check and determine if the problem is with the inverter or the battery. cause when inverter shuts down, I start it again, without my desktop PC+lcd, it shows 3 out of 4 backup bars on inverter with load ~ 120 watts (with PC + lcd its 180 to 200 watts)...

So what do you think the problem is?

NO. Screw you..!!

The fcuk you a-hole? :angry:

Yar na chawlain mar.... help me pleej pleej pleej :( :( :rolleyes:

Take you battery to nearest 'battery wala' and let him check if all the cells are working correctly. Assuming that you bought the new battery less than 6 months ago, the problem might be with the UPS if the battery is working properly.

pretty sure its a battey problem just like kashif bhai said.

main te ab se osaka hi le sa......

Assuming the load has remained the same, it seems like the battery has lost its capacity. If it is within warranty period, get it replaced. If not, still replace at own cost.

As a general rule, be very careful with procuring batteries. Many dry/SLA batteries imported here by various traders are at the end of their shelf life and near expiration. Unless you can be sure of legitimacy of the distributor/agent and the manufacturing date of the battery, avoid them. Also, due to our excessive load shedding scenario, there is too much battery cycling which results in early loss of capacity. In the cost of a single SLA battery, you can have two local wet batteries (usually recently manufactured/assembled) from known brands having warranty coverage. Plus, you can replace them when they loose capacity with fresh units in the same total cost of an equivalent SLA setup. Maintaining them and periodically checking and topping up battery water is however a PITA.

New Axiom inverter got some seious quality issues, assuming its in warranty, better check it with service centre to ensure its working properly. As for battery check with ur nearest battery wala as Dear Kashif bhai siad most probably battery has gone.

Very nice... Aise zaror help mile gi.. ::Middlefinger::

1 - get a PROPER Dc clamp voltmeter, preferably a Uni-T brand.

2 - when ups shows dead battery BEFORE (while beeping) and AFTER it shuts down, check battery terminal voltage.

3 - when dead and starts charging put the clamp on the red wire to battery and measure DC amps.

4 - when ups says battery full check terminal voltage.

5 - report all readings here

This D/D will easily identify which thing is at fault.

PS: screw you still Bayatch.

Thank you kashifmahmood & Arman Uddin for replying :)

Absolutely right you are, infact, and I am sure Farhan will also cofirm to this when I say, when I was buying the battery, I had detailed convo with farhan about shelf-life / manufacturing date about SLA batteries and relate stuff. and I knew about the pros & cons of SLA & normal batteries but I guess the thought of having a "Maintenance free battery" clouded my judgment cause that thought made me forget my location and the kind of mind-set I am dealing here with.

On top of that, I wasn't able to buy from farhan as I already paid another dealer here (long story). Now I think if the issue is with battery, it could only be due to lack of confirmation of the shelf-life of the battery plus I also think battery was already in use for quite some time... Had I been able to buy from farhan, could have been a different story.

And most funny thing is, the warranty period of the battery which was of 6 months, has expired 3 days ago :unsure:

Anyways, I'll see what I can do once the problem is pin-pointed and if its the battery, I will surly go for a normal wet battery if I can't confirm the shelf-life / manufacturing date.

Thank you for replying... :)

I will get the voltmeter tonight. I will test as per instructed and report back. BTW I am assuming by "terminal voltage" you mean the + and - terminals of...... the battery...? :mellow: :D

and funck you for replying my little dominatrix covered in shiny black latex :wub:

Okay... reporting back

I have got UNI-T model: DT830B from a friend. I hope this is good for our purpose...?

While beeping started it showed 10.51 Volts and continues to drop to 10.50, 10.49 ... and after when inveter shut itself down, it showed 11.80 VOLTS and continues to climb to 11.81, 11.82...

For the life of me, I can't figure out how to do that..... :(

when light came back and inverter started charging, it showed 13.6 Volts, when it was done charging after 45 minutes or so, it was at 13.6 to 13.59 Volts

Please see above...

So....?

Though I don't like to be the bearer of bad news but your battery seems to have reached end of life.

Is cut off voltage working properly? Or it keeps on charging and charging.....

3 - cz its not a CLAMP DC meter.. its just for measuring volts,. not amps. a DC CLAMP meter will measure amps.

4 - i would recommend you attach your battery to another up, borrow from somebody, other than homage. homage is a pretty unreliable brand for many many people from their feedback. its not designed to work with dry batteries anyways.. for few its working great but still many complaints.

Charge your battery on that ups for a long time. your terminal voltage at end of full charge is very low considering its a dry battery and ups is powering it.. still nothing can be certain until you can provide amps.

PS; personal opinion is that your battery was fine, your ups may have improperly charged and damaged it. battery dont go down flat in under a week. there must be either a problem with your ups (hopefully) or your battery may have been damaged by a surge or something..(not hopefully)

That is why i always advise getting a better ups instead of getting larger batteries first. spend more on ups first and buy better batteries next time..

that is why this is my golden rule for Power bussiness

PPS: Ultra Hadoken Screw you..

Just came back from the dealer... he says battery is not dead yet with 13.5 volt on his shop and its all due my homage inverter which has not been charging the battry properly... and he also says i need to get homage ups modified as per battery specs 14.5 volt max and 13.8 v average. and then he says he will totally drain the battry to 0 volts and heat it with a heater to melt down the the sulpher which has been accumulated on plates and then he will charge it for 1 or 2 days .... he claims "is ke baad battery bilkul new ho jaey gi" .... and he will charge 1500rs for this if can't claim warranty from main company in Lahore....

are those even possible?

3 - what if take my inverter to a shop to measure amps? or else tell me exact model of the UNI-T CLAMP DC meter so I can buy it

4 - Borrowing a UPS from another is not possible ... even if I can... it will still be an homage same model as mine :( any alternative?

Now don't be a dick, help a brotha in need, Homie

Any model of unit with CLAMPS.. just CLAMPS.. UniT 200-201-203 etc.. they are clamps models with DC amps and DC Voltage.

DONOT let anyone touch your battery.. its SEALED Lead acid for a reason.. unlike your virginity flower, it should remained sealed...once opened it will be ruined.. there are no specialist dry battery repair people..

all it needs is equalization charging to get back to full state.

3 - you would need to take your battery and inverter to shop for that along with wiring.. or you could just buy a clamp meter and it will be ultra useful purchase for all your life for all electricity purposes.

4 - APC.. you will need 2 batteries.

Fomo, who else is here helping you step by step?

PS:

Screw you many folds

a clamp meter is must for this , a DC clamp meter , use uni-T dc clamp meter which has AC and DC both options with a blue button model number is UT-203 , but you can use anyother clamp meter too .

The faulty battery has been replaced with apparently a new same AH/brand battery. The dealer was urging me to get my UPS modified to cut of charging according to the battery specs as according to him the UPS was under charging my previous battery but thing which is confusing how could I get the UPS modified when storage/cycle voltage ratings listed on this new battery & the previous dead battery are not same. and if I don't, same fate awaits the new battery in few months.

What is the science behind this?

explain'

what different values?

To cut off charge at certain voltage to the battery by UPS.

good info..
