Maintaining UPS/car batteries

[unstopabl3]

You can tune the charging rate by using on board variables. Maybe your brand new batteries were empty in start, once batteries are empty or in greater discharged state then ups charges them initially with heavy current. Let it discharge it fully, then put it back into charging, you may experience the same charging rate which you saw in the start.
Since it charges the battery in three different stages and you want it to be ready soon so adjust the first stage of charging rate to 12 or 13 amperes, charging rate for rest of the stages will automatically increase.
Remember, you cannot exceed the charging rate at first stage beyond 13 amperes which in your case is a maximum allowable charging rate.

No they were not empty, the shopkeeper charged them fully and they were fully charged when I brought them home, and everything worked fine for one week, just since yesterday all these weird things have started to happen.

If the batteries were at 28V and then charging continued I wouldn't have worried, but after 2.5 hours I saw 26.80V or 27.50V sometimes, now that's why I was concerned about the batteries health.

Also wanted to ask that if Wapda is not giving proper 220V and instead I'm getting 200-210V does this effect the amount of time it takes to charge the batteries??? If so would getting a stabilizer and hooking it up with the UPS help in quicker charging by providing constant 220V???

Thanks

You will be ok, as long this voltage is beyond as what is set by manufacturer. Like if output voltage drops to 180 Volts then few ups stops taking input from wapda and goes into the backup mode

secondly, you need to look into two variable charging rate and voltage on battery terminals simultaneous using your amp-meter and voltmeter to tell you a good story inside. otherwise, this will all confuse you.

So the stabilizer won't be any help???

I'll get this sorted out in the morning and test the charging rate and voltages afterwards and get back to you.

I talked to my cousin today he told me that get 2 rectifiers installed in the current ups and add a battery of 190amperes

What do you guys suggest?
He's already using this

Lol i get it ,
Ao i should just get the 175 ampere battery and plug it with the ups with no alterations right?

One of my cells is like this and rest cells are all right as before...may be this this the problem due to which my inverter keep on charging the battery....

[omer.s]

All other cells are like this...

[omer.s]

There is white powder type material between the plates of the one cell which i think is damaged

[Ishtiaq778]

u r right this cell is faulty.......might be short

[omer.s]

u r right this cell is faulty.......might be short

Ok thanx i will change the batteries to again osaka ips 1100 as before...
Anybody using osaka tubular batteries ?

Once you boil the water, later leave it to cool down then you see the same white deposits which are impurities originally present in water. De-ionized water or distilled water does not have same impurities present inside as they had been removed. Presence of these impurities does not tells you that batteries are good or bad. You will have to check electrolyte gravity, perform load testing and see the backup time to determine the condition of batteries. You can get rid of all these using a flush, but that should only be performed if you surely know if battery can be recovered or not.

buy any series from any brand which has been specifically manufactured for ups as they have think lead plates as recommended for the application. so far, as per my knowledge ugs grade series from pheonix is specifically manufactured for ups application. if you know about any other brand then bring that in our knowledge.

First, suppose your cutoff voltage is adjusted to 28.8 Volts then you would want to reach least 28 Volts in least amount of time. Least amount of time is what you need to determine by looking into your load shedding schedule. If later it starts to charge you battery at 1 amperes or 2 amperes of current then least this will protect your batteries from forming sulfate crystals, keep it topped up for the load shedding which may arrive at any moment.

Bill is a tricky question, power which will go into topping up the batteries will consume more bill, more units down the line. Alternate to this is that you adjust such that your ups charges the battery in last stage at 3-4 amperes of current. Sooner, it will hit your cutoff voltage then charging will stop at all. If last stage charging is at 1 amperes then it may keep on charging the battery for around 8-9 hours maybe.

Example, if cut of voltage is adjusted to 28.5 volts, then you would want to hit it soon by tuning the ups otherwise it may never stop but since you can see it is above 28 volts so you know you are safe or batteries are ready. There is a slight tradeoff, if you want to see a good battery gravity then this one amperes of charging at last stage is very good, you can tune this to hit 28.5 little sooner and avoiding more bill. Making sure, bill and specific gravity readings remains in balance.

More, you will play around, more you will see things and make out what is better for you. I say, in last stage, it should not take so much time, as otherwise bills haunt us later. That is a problem on imported ups that we cannot do anything about it as what set by factory is set for good but in local, we can play around.

So I took the UPS to a shop and told him exactly what I told you, he checked the UPS and told me the transformer is weak/buggy and if I get it repaired it will be 3-4K BUT I should get it replaced which will cost 6-8K.

He also suggested that I should invest in a new UPS instead as this one is old and doesn't have the ability to adjust the voltage fluctuations we see nowadays. He said he has three qualities of UPS he can make me, starting from 10K with cheap stuff, 13K with normal quality stuff and 16K with high quality stuff and 1 year warranty.

I told him that I just spent 23000 on these two new batteries and honestly don't want to spend anymore, he changed the charging wire from medium Amps wire to max Amps wire and said this should fix the issue for you temporarily.

I cam home hooked up the batteries and it charged the batteries in 40 mins, I was surprised so I hooked up multi meter during next charging and was shocked to see charging at 30A, then from time to time it reduced a bit until it got till 22A when the charging finished.

The battery terminals were hot as hell and the transformer of UPS was quite hot as well, I knew that can't be good for the UPS or my batteries. But it did charge the batteries fully in less than an hour after 1 hour of loadshedding, so that was good to see, but I know it will ruin my batteries eventually at such a high Amps and my bill will be outrageous as well, right???

You are using outdated kit in your UPS.......If u simply upgrade kit to IC 104 or iC 105.......ur problem will be solved.....i requested u to upload pic of ur ups kit but..............

[Ishtiaq778]

Terminals of become hot when not tighten properly..........Terminals are loose on poles of battery or ups wire is not properly tight in terminals. check it.

[Ishtiaq778]

charging at high ampere like 30 is very dangerous. When your batteries will deep discharge, your UPS will charge @ 50+ ampere and ur ups transformer may burn out. So i again request u to upload pics of ur opened ups........transformer, kit, module etc

You are right .......but if its electrolytic fault then, all cell should have these white precipitates. This happens because of manufacturing defect in the cell and its not reparable by any means , only replacing the cell is the solution.

UGS series is definitely good battery by phoenix. talhawaleed rightly said.

Any battery having thicker plate is quite good for use with UPS.

Ok i got it. Thanx alot i will go for phoniex this time
