Maintaining UPS/car batteries

[epigenius]

what about that factory charged thing?? battery comes pre charged with fluid from factory?

[unstopabl3]

14.30V is best.......this kit has 3 stage charging .............if u set 16A...........2nd stage will be 8A ....3rd stage will be 4....3..2 and full

And what if we set it to 15A ( the recommended charging for my Phoenix UGS 175 batteries ) what will be the stages???

And isn't this 3 stage system called trickle charging? or is that something else?

Also additional query, regarding initial charging, If I want to charge more than the cut-off voltage 29.2, Is there any way to hack the external charger I am buying to make the batteries charge more than the cutoff 29.2 volts?

Some time AGS company provides batteries with electrolyte.........and a sticker is pasted......factory charged guaranteed.
I heard from unreliable source that, factory charged batteries are those which were returned to company in Claim......company remove the fault and recharge it.........ready for sale..........

Dear, you can calculate easily.....2nd stage charging is 50% of 1st stage charging........and 3rd stage is 25% of 1st stage charging.
Trickle charging is something else....

Trickle charging means charging a fully charged battery under no-load at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level.

If you buy charger with manual adjustment, then you can charge your battery more that 29.2 level.......other charger cant be hacked if programmed already

I read the return policy of AGS, I don't know about others but I find it very stupid, fault in 1st month, battery changed with new one for no cost, in 2nd month you pay 1/6th of new battery price similarly 2/6 in 3rd month 3/6 in 4th month , 4/6 in 5 month and 5/6 in 6 month and after 6 month warrant expires...

There is no way you can hack an automatic charger to so this, because the charging is controlled by a micro chip. However you can make a simple manual charger cheaply that outputs at least 14 volts at a constant low current. But it is important to monitor battery voltage frequently to make sure you don't go over the limit or overheat the battery.

There is no warranty sharranty, it's all topi drama really, when you go to the seller they will make laakh bahane and either tell you the batteries are fine or will tell you it's your fault and it's not covered in the warranty.

@whiteangel please tell me how? I can measure output with digital volt meter with 1 decimal accuracy. It has been checked with multimeter and it measures correctly.

What should be float charging voltage and bulk charging voltage for 4 batteries (48 volt) setup?
I have set
bulk charging (c.v)=56
float charging= 54
is it ok?

@whiteangel please tell me how? I can measure output with digital volt meter with 1 decimal accuracy. It has been checked with multimeter and it measures correctly.

Most digital volt meters come with one decimal reading, so just make sure you buy that one. As far as accuracy is concerned, it depends on the make. some might me more accurate than others. You can double check accuracy of the volt meter by verifying with a multimeter.

Yes it did.

The last time we went for factory charged GX200F battery, it lasted 4 years, with proper maintenance.

But factory charged battery has less shelf life than dry charged batteries. So it is not very easy to find latest stock.

@talhawaleed AOA, bro from the last couple of days my UPS is creating problem when the Electricity is OFF and UPS is ON. Battery charging and battery are fine but when the UPS is ON and starts delivering the current; even the energy saver glows but a minor blinking can be seen and the Fan moves with a very low speed while the positive terminal of the UPS which is fitted on battery positive side heats up very much.

Brother what could be the fault in my UPS? Please reply me i am very worried about this behavior of UPS.

Thanking you in anticipation.

@talhawaleed AOA, bro from the last couple of days my home made local UPS (working from last 06-07 years) is creating problem i.e. When the Electricity is OFF and UPS is ON. Battery charging and battery are fine but when the UPS is ON and starts delivering the current; even the energy saver glows but a minor blinking can be seen and the Fan moves with a very low speed while the positive terminal of the UPS which is fitted on battery positive side heats up very much.

Heating of wire is the problem.........Terminal of battery is not tight properly on pole of battery Or......battery wire is not tight firmly in the terminal.

Buy new terminal.......Cut the red battery wire to get fresh wire..........if you have soldering iron (kavia) then sold this wire and then tight in terminal......your problem will be solved Insha Allah

By default, you will have to replace all the internal wirings of your UPS as this will remove the blinking and shortening issue and after having done this then you will have to tune your UPS.

Terminals normally get hot if they are corroded as very less current is being delivered to the batteries resulting in being hot due to a very small contact area or very high current is trying to make its way to batteries with small contact with terminals.
If above issues are checked and problem remains intact then it may be a problem with batteries.

Anyway, you should have an amp-meter and voltmeter with you and should exactly know the settings which supposed to be running on your UPS like cutoff Voltage, charging rate. Then verify those with meters and see if settings are right or not. There are too many variables involved and they are easy. Purpose of this thread is that you should rely less on technicians and more on your skills, instincts and knowledge. It can be anything, try to diagnose it with meters and if you don’t understand then post results as otherwise its difficult to say anything.

You should not try to charge your batteries above 28.8 volts or 14.4 Volts, that?s an extreme point and beyond is not good.

Anyway, if you want to do this on your new batteries then I would advise you that you keep the cutoff voltage to 28.8 and decrease the charging rate for last stage charging to between 1-3 amperes.

That will server your purpose, will improve the S.G provided you let it charge fully not having any load shedding in between.

@whiteangel

Bro what I meant to ask was not regarding the accuracy of digital volt meter, that already checked with multimeter from the same shop where I bought it. I was asking basically how to make a 14 volt constant charger as you mentioned here: https://www.pakwheels.com/forums/mechanical-electrical/153379-maintaining-ups-car-batteries-139#post4869850

Also another query when the battery is being charged by UPS, by connecting volt meter on the terminals of the battery, will it tell the correct voltage of battery or will it tell the charging voltage coming from UPS? I mean to ask that when checking voltage of battery, Can we check voltage when battery is being charged or do we need to turn the charger off and then check for correct reading?
