I tried getting an electrician but the state of loadshetting is so bad here. The light goes after every 2 hours or so. I don't stop the charging when the light goes. The UPS isn't being used. It just charges the battery when there is electricity.
I do think my UPS does indicate when the battery has been fully charged. But till now it's still in charging state. I checked the battery and it wasn't hot or very warm. Plus when I opened the lid, there were bubbles. So I don't think the UPS has overcharged it.

Any other way to check if battery has been sufficiently charged or should I just continue to charge until the UPS indicates the full charge?

u need a digital meter .. either an electrician can do the job or else buy a meter n check it for urself now also this meter will help in future to monitor ur ups n batteries .. to use the meter u can ask for my help netime ..

Nope, will not make a difference. usually new batteries are filled with acid which makes the cell charge initially but a new battery needs to be deep charged before the first use. But honestly it will not make a difference. Charged or not you can use it as long as you do not drain it completely on your first use.
Thanks for the reply. How do they keep it charged by still keeping the cells new? And for how long have they been charged for? I mean usually you give an advance payment to the shop guy and they charge it for a single day or a couple of hours for you.

Ummm actually. It should, and it will make a difference.

The theory of Lead-Acid batteries can be traced back to simple, high school chemistry. It is nothing but a reversible, electrolytic cell, where by each Lead cell has the capacity to hold 2.1V, and the current depends on the size of the cell.

It is noteworthy, of course, that batteries can't 'produce' or 'generate' energy, they can only store it for later use.
Without acid, there would be no way to 'charge' the cells in the first place, or, in easier terms, there would be no 'charge' in the battery. The cells can only give back what they have retained.
The acid, or, the 'electrolyte' is what causes the transport of energy to the system. Without the acid, there can't be any flow of current. Without any flow of current, the lead plates are as good as poisonous rocks.

So, in short, when you have a 'pre charged' battery, the only way for that to happen is if they have either added the acid already, or, if they add the acid, very quickly burst charge it for a few minutes at a very high current and surge the cells, both of which are bad for your battery.

Once you add acid to the battery, even if it is sitting there unconnected, the process of its deterioration has begun even if you don't use it. A chemical process called 'Sulfation' begins on the plates, which is why your batteries eventually become less efficient, and, eventually die. Of course, this process is much more appreciable when you are putting the battery through charge-discharge cycles (sulfation is primarily in the latter of the two phases), however, the battery does start to age.

So, if you have a battery with pre added acid, it's going to die out sooner and be less efficient more quickly.

And, if you have a 'pre charged' battery whereby they quickly charge the battery and give it to you, then, again that's not good for your battery. Higher currents will cause (much) higher temperatures in your cells, which will lead to not only water boilup, but also, high temperatures very adversely affect the battery. And, of course, you won't be fully charging the battery (which is what should be done with new batteries), you would only be providing a fraction of it with current and then trying to get to the top, reducing the efficiency drastically.

As a rule of the thumb, the maximum charge rate a lead-acid battery should be given is C/5, and the recommended charge rate is C/10, generally. We tend to charge them much faster, in our UPS's, by the way, which leads to shorter battery lives.

(C/5 means max charge should be 1/5 x Ampere rating of battery)
(Or in even simpler terms, the recommended charge rate for lead-acid batteries would take the battery TEN times as much time to charge is it took to discharge).

Normally new batteries are dry charged from the company. These need only acid to activate. They required only float charging.

Want to post a review of my month old purchase of desi made UPS sold by [MENTION=26350]umair23[/MENTION] here on PG. Decided to upgrade from my standard 'chopper' UPS. Main reason behind upgrade were the following:

  • Loud fan noise while charging
  • I knew it was inefficient because Chinese made UPS don't use real copper but silver coated with copper paint. Seen this in person as well at a shop
  • Ability to see load and battery voltage level remaining in real time
  • A lot static sound in electronic equipment which I knew was screwing it up. For example the standard dimmer kept on breaking down, very loud static sound in my PTCL Fiber Optic telephone line and other random occurrence.

Basically wanted to use something really good and within budget. The UPS had cost me 14.5k for 1000 Watt maximum load cell configuration and it's PURE SINCE WAVE. The difference between the regular square wave and sine wave is astronomical. Now the issue is, I can't even tell the power going out :'D There is absolutely seemless power transfer EVEN while using your desktop workstation and gaming! It's super quite too because the fan only kicks in when the component temperate hit the threshold value of 55 degree Centigrade. This was a major plus point as the UPS is located in a place where family gathering and people talk. The chopper US was loud AF! [seriously]. It has a digital LED display which displays current statistics in real time,
  • Battery Voltage <- estimating amount of charge remaining. It dies at 9.0V starting at 14.0V. It hasn't dipped below 10.5V with my month usage of 3 fans, 2 energy savers and computer running on UPS for one hour.
  • Incoming AC Voltage
  • Outgoing AC Voltage
  • Total Watt Load <- this is awesome

Installation was simple as [MENTION=26350]umair23[/MENTION] guided in the electrician and he did his job under 10 minutes. Simple and fast. The UPS is legit guys. I don't see ANY point of people buying standard chopper UPS these days when desi made like sold by Umair are being RIGHT in Pakistan. It's a superior product EVEN if you pay a bit extra. You get EXACTLY what you are paying and then some.

Can't give a balance review with a con can I? ;-) One of the thing a bit bothering is [MENTION=26350]umair23[/MENTION] having the sound indicator volume set to very low when power goes out or comes in. It's like a double edge sword. It's good that it provide a seemless power transfer but it doesn't give you the opportunity to turn off extra lightening putting excessive load. Like in one instance, I had total load of 700 watts on it! Had to turn off tube lights and ceiling fan to bring it down to good'ol 300 watts. Very rarely there is this super low but high pitch sound. It sort happens sometimes but it's not a big hindrance. I think it's even gone. But just wanted to point out. According to Umair, it's from the MOSFET thing he might be using. It's not a big issue. Oh yea, it's heavy AF. That pure 1KVA transformer in it gives the weight. When you pick it up, you know you paid well for it :p

I highly recommend people getting this over regular desi made UPS with a VERY important feature, PURE SINE WAVE! Protect your electronics!

If you guys have any question pertaining to real life usage or I missed something here, do let me know. Will do my best in assisting you.

My UPS stopped working today. However I would have to wait till the end of this month to get a new UPS. What worries me is that the battery won't get charged during this time and it may become unusable. Is there someway that I can protect the battery before I get the new UPS?

yes it ll b unusable ... just ask ny fren or neighbor to use ur battery till u gets new UPS ... thy ll be happy to use urz to get more backup ... attach ur battery with that ups which works with single battery so that u attach ur battery with his battery parallel ... make two jumpers n connect the two batteries positive to positive and negative to negative .. in this sense both batteries ll be in working condition ... in this case no one ll say tht if i use ur batttery thn wot ll he do with his battery
