Maintaining UPS/car batteries

[elxlr]

5000watts stabilizer is enough for 1 ton AC OR enough for complete house load except AC. Agar lahore mein rehtay ho ap aur itna bara chahiyay tu btana. You will get a better one. But keep the stabilizers out of the rooms where u sleep. It makes noise while using relays.

slam brothers ..

@elxlr .... brother mai Karachi mai rehta hou .. !!

ap brothers ka prompt reply mere leya bohat helpful hain ..

any way mai ne ups par stabilizer laga lia hai ... es k baad k inspection k mutabik ...
stabilizer lagane se pehle inverter battery ko 16.45 amp pr chage kr raha tha .. jb k stabilizer lagana k baad inverter battery ko 17.80 amp pr charge kr raha hai .. stabilizer lagane se voltages stable hoe hain .. KESE jb aa rahe hoti hai toh input pr stabilizer lagane se 220 volt inverter ko ja rahe hain js se fan standard speed pr chal rahe hai .. but light jane pr .. fan slow ho jate hain ..

kia brother meri help kr sakte hain .. ap logo k pass jo inverter lage hain es ko bkup mode dal kr es k output voltage bata sakte hain k kitne aate hain ..

mai ne apne inverter ko backup mode pr chk kia hai es ko backup mod pr dalne k baad es k backup voltage srf 165 voltage hote hai ..

ab ye bataeyea k ye battery ki baja se kam voltage ho rae hain k inverter theek kam nahe kr raha ..

waiting for your all valuable replies ..

Thanks ,....

bro screen pr jo voltage show ho rahe hote hai vo fake hote hain homage pr ap multimeter se chk karain ..

227 voltage toh mere homage ki scrren b show krti hai but multi meter pr 165 hote hain ..
kindly chk it again ..

Mera UPS 255 volts deta hei backup per. Multimeter pr bhi. Abid (my electrician-cum-brother) ne khud hi zyada rakhay keh load parnay per sab chezein achi speed dein aur jalein bhi na. Jab load parta hei tu 235 volts tak pohnch jaatay hen. I'll check again for you. And ask Abid about your issue that after installing stabilizer and UPS BACKUP VOLTAGE ISSUE which is 165 volts as confirmed by other brothers too. New problem for me to learn. I'll ask him. He'll educate me. And I to you. Thanks.

[elxlr]

You can see my UPS giving 255 volts on backup and even at 120-140 volts it is charging the battery. Our transformer blew up that day and was giving bad voltages. Once a year or twice that happens due to rain or anything.
Another blue UPS is of my relatives. Maybe you can see the voltages or not. Picture was not clear i dont know whether it is backup voltage or charging voltage picture. Let me see after pics uploads here.

Yeh UPS mein lahore se banwa kr laya hn. 400km door se. Aur agar kharab ho jayein tu lahore hi bhejnay partay hen. Per i still took the risk and enjoying since. Kharab hi nhn huay. Donoun ko dosra saal hei. Not even one problem. Blue walay ka problem na honay ki vaja se problem aa gya. Us ka on off button kharab ho gya. Tu poora check krwanay ke liyay multan se lahore le gya jab chakar ban rha tha. And he replaced the old buttons and fixed some settings or variables.

thank u @elxlr ... for brief .. response ... good to hear you belong to Multan ... my fav city ...

ye mere leya amazing point hai k desi ups ap k pass itna acha chal raha hai ..
mai ne b banvaya tha .. vo mere pass 2 yr chala phr battery kharab ho gae ... os k baad se vo mere pass aise he rakha hoa hai .... !!

abi ye homage 4 month pehle lia then es mai b issue chal raha hai .. ap k reply ka inteezar rahe ga ... regarding low voltage issue on bakup mode .

here are pix of my old ups ....!! es ka transformer original copper hai ..

[elxlr]

I asked Abid about your issue. He said UPS MEI FAULT HEI. Usko agar warranty hei tu check krwayein. Warna jis trah se woh 4 months mein issue de rha hei tu battery mei bhi masla kr chuka hei.

Company waloun ko dikhayein tu woh OK keh kr battery per ilzam lagayein gay. Apnay paroun per paani koi nhn parnay daita.

Old ups is fixable but u will have to send to Abid to get a good fix about it. Desi ups is repairable and customizeable as much as possible as many times as possible. Not the inverters. Aik do baar repair krnay ke baad unki kit hi kharaab ho jaati hei. Which sometimes even companies dont fix or make.

He says keh agar waqai inverter ka masla hei tu koi jugaar laga kr chala sktay hen if company doesnt fix or says its ok and blames battery. But jugaar phir jugaar hotay hen. Kitnay arsay tak chalein gay. Another problem a jayay ga. Phir koi aur.

Battery ka backup kesa hei??

He said keh itni bari full sized battery ke liyay bhi 17 amp kam hi hen.
Aur jab charging kr chuka ho. Tab check kijiyay ga amp meter se keh tab bhi halki si charging tu nhn ho rhi!?

He also asked me keh " yeh bhi nhn pata woh amp meter halkay wala use kr rhay hen ya achay wala. ".
He said keh battery jab 4-5 ghantay charge ho rhi ho tab haath laga kr check krein side per kahin garam tu nhn ? Neem garam se zyada garam hogi. If yes, then you battery has been damaged.

@elxlr .. thank you ..

1. Inverter warranty mai hai .. approx 4 month old hai ...

2. battery ka bakup acha hai .. last month es se 2 fans pr 6 hour ka backup lia single fan
   pr es ka backup approx 12 hour .... abi b sirf slow ka issue hai backup i think theek he
   hoo ga ..
   ..

3. old one .. ups krva toh lou repair .. but bhaijna dushvaar hai .. vo b Lahore ..

4. amp meter Unity T203 clamp meter .. famous meter hai .. pro personal ko use krte
   daikh he mai ne purchase kia hai ..

5. charging complete krna pr ... approx es mai 0.65 amp se charge ho raha hota hai ..
   "mannual k mutabik ye process stable charging khalata hai it is normal according to
   company mannual"

6. battery garam yea hot nahe ho rahe he just warm jese firt day thi..

[elxlr]

Stable charging waghea kuch nhn hei esa. Darama hei.

Bas saal nikaal jayay kaafi hoga apke liyay. Baqi Allah barkat day. in sha Allah.

It's the float voltage. It's to keep the battery charged if battery backup is not in use. Usually it is necessary for maintenance free batteries. Not very good for flooded batteries. If there is no load shedding, manually run your inverter on backup mode to prolong battery life.

[elxlr]

Yup, not good for flooded batteries. Yet they put this option without telling which battery their inverter is suitable for.

My ups if there is no loadshedding for a week. And after properly charging the battery. It will not use any amps or won't be charging the battery at all not even in the entire week. But after one week there will be some kind of slow charging once a while to keep the battery healthy. As another user (i think deltree or some name i forgot) who bought from my friend told and affirmed a while back ago.

[Atif_Jawaid]

thank you @elxlr and @ch.talal ...

@ch.talal ..... load shedding to aisi hoti k mat poochain ... es thande mosam mai b 2.5 hour ki load shedding hai ... 2.5 hour multiply by 3 .

@elxlr ... nxt dafa dry yea jel battery purchase kro ga ....

[elxlr]

You welcome brother.

Next dafa bhi agar ups yahi rha tu dry battery phula sakta hei ya damage kr ke backup kam de skta hei. Mtlb yeh keh jitna backup maslan 8 hours on 3 fans meri liquid battery 16000 rs ki day gi. Utna backup 8 hrs per 3 fan 20000+ ki dry de gi ganday inerter ya ups pr. Jab keh uska real result 15-20 ghantay 3 pankhoun ka hona chahiyay.

Per log becharay aik chez gandi lenay ki vaja se dosri achi chezoun se normal kaam hi le sktay hen na keh unki maximum safe limits tak.

Pakistani local mobile companies ko dekh lein. Advertisements karooroun ki kr di. Chez ki resale value nhn. Quality nhn. No R&D center. Research n development center.

Same with inverter companies.

Yahi dekhta hn. 1.5 liter Aqua fina ya nestle ki pani ki bottle 35 rs ki aati hei whole sale per 6 pack mei. Aur bikti 50 rs per bottle hei. No problem. But jo new companies hen ghatiya paani kuch ka. Woh bhi dukandar 50 per sale kr rha hei. Logoun ne hi kaam kharab kiyay huay hen. Aur woh factory se maybe 15-25 rupay per bottle parta ho.

Ab Halka feel ho rha hei bhraas nikaal ke.

Dear @elxlr
Which battery brand is better for UPS battery ?

[elxlr]

I only know what my electrician tells me.

And its AGS battery. Flooded or liquid ones. I don't know about dry cells.
But dry batteries take less amps to charge. And give ALMOST double the backup of biggest liquid batteries Of same specs.

Its my 2nd AGS battery and recommened AGS. To a relative. So i have had experience of 3 batteries. All working flawlessly for minimum of 1.5 years and then i changed my last battery because needed more fans to run on that dying battery so replaced it. And now this battery i bought since April and have'nt refilled the water yet (because ups is good) . Not even once. Except once cell which i feared was defective but is ok now. Backup is strong. 8 hours on 2 fans and battery is still remaining 50%.

Idher battery ka 5 month mei paani tak kam nhn hua warna kharab inverter ya ups tu backup bhi kam kr daitay hen itni dair mei.

[shariq101]

Thank you

Someone here has tried Daewoo batteries (Maintenance free) in his car ? Hows performance of these batteries ?

[Atif_Jawaid]

@exlr ...... ha ha ha ha ha ha....!!!!

brother yahan ka aave ka aava he bigraa hoa hai .... !!!
mai ne apna inverter waranty mai dia bari mushkil vo sahab maanae k inverte mai problem hai ..
own sahab ka issraar tha k ap k fan k capacitor kharab ho gae hai .. jab own ko samjhaya k bhai .. inverter k bakup pr ap voltage chk karain k sirf 158 volt A.C aa rahe hai toh kia khaak fan theek chale ga ... multi meter b mai apna le kr gaya .. sahab k paas chota sa multi meter tha .. or vo baazid th k mera meter kharab ho jae ga ...
bahar hall warranty mai de dia hai ... umeed hai k theek ho kr aajae ..

1 din se load shedding ki timing mai andhera jhail rahe hai ...
reh reh kr apna porana 1kva ka generator yaad aa raha hai ..
aaj jaa kr os ko service krvata hou .. ups se acha toh vo he tha ... 2008 mai lia tha 2 bar engine bna ... 2016 mai os ko retire kia ... lekin lagta hai .. os ko b ready kr k rakhna preee ga ...

[elxlr]

Bas bhai inverteroun se jaan churain chahay solar pr ayein ya generator ya good ups makers ke paas. Aur woh china wala inverter na lein jis ki itni mashhoori bhi nhn q keh kharab tu sab nhn kisi na kisi waqt hona hota hei per kammahor ke parts bhi nhn miltay aur repair bhi mushkil aur nuqsaan sab ka. Owner ka bhi aur dukandaar ka bhi. Keh bechara check krta rehta hei fault trace ho jayay ga aur apnay paisoun se samaan laga daita hei. End per pata chala na piece mila aur fault aik nhn 5 thay aur 5vein fault tak pohnvhtay uskay paisay bhi lag gyay aur woh bhi theek na hua. Just happened with my friend yesterday.
