Ishtiaq brother my desi ups stops charging at 14.12volts. I have set it at 14.20. Is it all right?

14.20 is fine.

[princelibra]

thats good............no issue

dear ishtiaq sb aoa

in pakwheel forum u posted some where the follwoing picture:-

according to this information a UPS should charge the battery according to that formula given in this pamphlet which is 5hrs capacity/5..... which in my case that is UGS 175 battery ...........110/5= 22amps......

110 is 5hrs capacity according pheoinix manufacturer data sheet which is as under :-

so my question is the formula u mentioned is correct or this one...i mean amp/10 or this that is 5hr capacity /5

for my battery it is 132 amp/10 = 13.2amp
for 5hr capacity 110/5= 22amp

so at what charging setting my homeage UPS should charge... kindly inform me

In start, I read few documents which clearly stated the maximum allowable charging rate as function of 20 hr capacity to be amp-hr rating/10. This still is valid for UPS which charges the battery on flat or same charging rate.

Your question is a good question, which prompted me to look at different sites. Currently following sites quotes this.

Note that above table is valid for deep cycle batteries but here in Pakistan non of the manufacturers claims their batteries as deep cycle. These ordinary lead acid batteries can only be discharged to 80% of their rated capacity before it requires to be charged again. So only content in above table valid for your case is the last entry.

Table only says, that if your lead acid battery is heavily discharged then you can charge it at higher rate initially but later charging rate has to slow down to Amp-hr/10 and even further at later stages.

Above are the maximum limits imposed on charging, which should never be exceeded.

Wslam.........Bhi jan best charging rate for your battery UGS 175 is 15A.
Slow charging is always good for battery health.........

Ishtiaq bro my desi ups low battery cutoff is at 10.36volts. Is it right ?

[Ishtiaq778]

10.5 is ideal low battery cut of........10.36 is acceptable.........no problem

[sad123]

Ishtiaq bro
There will be no problem to battery ?

[sad123]

[Ishtiaq778]

There will be no problem to battery ?

yes no problem dear

[jamalkhanjani]

how to perform EQ charge to battery? Are there any chargers avalaible in local market which provide such functions like Equalization or adjustable voltage/amps etc

[sad123]

yes no problem dear

Thank you very much bro. :*

Aone Spark battery water Vs ordinary home Tab water

Here, I got my hands on Aone Spark battery water being sold in a beautiful bottle for Rs. 60 per 500 ml. Aone Spark TDS value turned out to be 741ppm, I think in order to make it look more attractive to customers, they add red color in-ordinary tab water which further degrades the TDS value.

Second test again performed on my home Tab water, I am impressed that TDS value turned out to be 217 as compared to 195 as previously recorded. This is a running water and change in TDS value here is as expected.

[asjdsm]

Bro any test on ags battery tonic or a big 5 ltr bottle of water that is available at Shalimar chemical shop saddar bazar rawalpindi. Near chick bazar.

I bought 5 ltr @120rs from them. They say it's chemical /experiment grade

Mr. Talha did u check the TDS of AC water...please post the results.... bcaz its more dionized i think ...

thannx

Will be buying new battery for my 1KW inverter, old volta gave up after 4yrs still has some juice if i properly flush it but i would be buying new one. Getting 3500 for this 200AH volta. Now searching for something 175-200AH Volta Ags or Exide. Ags is quite overpriced these days, 165AH going for 13k

[ahmed2396]

Bought Volta 180AH 23 plate. Filled with 1250SG Sulfuric Acid. Battery is said to be Platinum model, it has more % of lead and some platinum in it. I don't know what philosophy is behind this, but lets see if this one also goes upto 4yr mark. Market is flooded these days with Volta and Exide very less AGS and Phoenix the reason they are expensive and have zero replacement warranty.

Brother, I could not get my hands on AGS tonic, I have asked many shop keepers but unfortunately they did not had it. I will search and test every battery water available in Pakistan and will post the results here.

Above tests done had a very disappointing result, I wish if someone can bring this into notice of enforcing authority so that they may raid and impose a heavy penalty on them for fooling the public.

I will try to buy the water available at Shalimar.
