Are they new? Can you email me the data sheets at info@atlanticwastepower.com

They're not new. I have also posted their website above for any other information you may need.
Many thanks

Truly, locating where to connect the two cables from the DC fan could be tricky. I don't really get what said here, especially where you said, "then locate the point of the other leg on the board of the UPS."

Let me break it down, you will need a multi meter to do this. Connect the negative leg of the FAN to the negative of the battery and connect the UPS to its battery then power ON, look on the board for the point that gives us the voltage of the DC fan, it could be 12v or 24v using the red cable of your multi meter. Make sure you get a point such that when you switch OFF the UPS light goes OFF from the point otherwise your DC fan will continue working indefinitely.

Are these batteries brand new?

They're fairly new but very clean batteries

FxDominion:
Getting it down to me in Abeokuta, what will total overall cost be, I need one for now.

This is what i usually do, i'll get it to the park, link you up with the driver as per the cost of transportation and you pay the transport cost on delivery.

FxDominion:
Pls Feflo, on what condition will I need 24 volts system to power my appliances rather than 12 volts or is it a matter of choice?

24vdc allows you to power more with reduced current capacity. I'll go for 24vdc system over 12vdc system.

DUNKA:
does this battery come in 200ah?

I doubt if they come in 200ah but I believe there are higher ah than 100ah. I only have the 100ah for now.

Thanks

Now available Northstar NSB 100FT SILVER BATTERY.
12V 100ah with a life expectancy of about 10yrs.
35k each

casig:
Good morning. Please how much is that 10 amps 12vdc charger?

10k for the charger only.

FxDominion:
@feflo: How much is your 12v 200ah fairly new battery if it is available, what brand and how long is the guarantee?

Yes, available, I presently hàve MHB. It costs 35k and the guarantee on it is 3months.

Couple it and ready for use/delivery.

To get output from the inverter, you will need this cable. It's called IN to IN power cable or MALE and FEMALE, it's a computer cable. Cut it in half and connect the end of the female side to a socket as shown.

Look for the buzzer, usually on the board and remove it.

The attached pictures shows how I extend my cables

Locate the DC cables, black and red usually, extend using additional cables, preferably red and black.

I've opened it up, as you can see it comes with a DC fan, making the conversion relatively simpler.

Introducing the materials and tools that'll finish the job.
Screwdriver, socket, lugging machine, insulation tapes. Side cutter, pliers etc

I am presently converting the 1.5kva 24vdc APC UPS to inverter and I'll be uploading live pictures here. As a rule I'll love that we don't post anything until after the conversion. Thanks.

My regular inverter

They're thesame technically

This is the wicked inverter and the unfortunate battery

This is a very harmless inverter, I've installed a couple of it. Surprised that it could cause that kind of damage. The charging amps is even less than 10amps.

olabakefish:
So please what is the way forward am so confused now that things are tight, I was able to get things without stress, now I dare not cos of finance. It's just so painful, my friend that got his before mine is still enjoying it.

Kindly call me on 08023662352 or 08165304602.

casig:
Please how does one determine whether a UPS you want to convert to an inverter is 12vdc or 24vdc?

It's usually determined by the number of batteries you find in it though there are exceptions. One battery means 12vdc while two means 24vdc and so on.
Thanks

I can't tell the exact mistake I made, what happened was that I saw the inverter with a guy that sells power tools like drilling machine, grinders and the rest, he only happens to have the inverter in his shop and I asked him if it works and he said it is working fine, we could not even test it that day as there was no battery in his shop since that is not what he deals on. I was desperate for that inverter because the one at home was bad, he gave me his word that I can return it if it doesn't work, I connected it to my battery of less than 6 months brand new slim Ritar 200ah and there was light all night till 6am the next morning, then I put it on blving that it must have charged very well only for it to go off in 20min. I couldn't do anything about I left till I came back from work and I was told that there was light for considerable hours so I bliv it must be charged like the new one does only for it to do same.
I called the guy he asked me to bring it on getting there I tot he will refund my money, collected it and told me tp come back some days after that he would have fixed it, I he went back on the said day he gave back to me and was requesting that I give more money and I refused collected the inverter and left. During that time I had located the service centre and fixed my new inverter that went bad that's when I noticed the battery had gone bad. I took the inverter from the guy straight to the office and connect it to the battery in the office in less than 30mins it ran down a battery dat lasts hours, that went I knew I had use my money to buy wahala. The inverter actually damaged 2 batteries, one at home another at office, the run time for the at office was seriously reduced to like 45mins after the incident. That is when I new the that the inverter was the culprit. I just dump it somewhere. I will post the picture later for you to see. The most painful part was that I had a blue gate ups at home that I could have converted in the meam time. So when I stumbled on this thread I felt like crying because the cost of the battery now is so painful. With the way things are in the era of CHANGE. So please what was my mistake...

I don't think you made any mistake, the problem is caused by the inverter.

Engr feflo,
Weld one bro, a great job you are doing here, I will soon contact you for my 1.5kva ups, meanwhile the man I installed the other smart charger for is enjoying it.
Thanks for the good work.

Many thanks sir

olabakefish:
I can bliv I read all the tread in one day, you ar indeed a blessing to this generation, I wish I had seen this thread earlier, I made very costly mistake that damaged my 200ah battery rita slim, I bought a used inverter from someone when the new one I bought blew up due to overloading, while I was trying to look for how to repair. I saw it very cheap and jumped at it, only for it to damage my battery which is now very expensive.

Please is there anyway the battery can be salvaged. It doesn't charge more than 3 minutes and when load a single 16w bulb the inverter starts to make.

Note I have fixed the inverter that blew up at their service centre.

Thanks for your compliments, really so sorry for your loss and hope you have learnt one or two things from it. I'll be glad if you can share the mistake that led to damaging your batteries here so that we all can learn from it. I personally don't know any technology that can be employed to salvage dead batteries. I'll love that you call me so that we can together look for solution to the problem at the most minimal cost.

Many Thanks
