U can buy direct from some dealers in Nigeria or u can order from aliexpress.com with ur debit card

a ups is an interrupted power supply wic conversation a DC to AC, as it was known that most of electronics gadget conversation the AC to DC while electrical gadget make use of the AC direct

vansledge:
OP, how can i know a good fairly used btty (any mins of testing?) my location is not lagos...
thanks

D set up is like charging ur fone with a desktop charger.Connect d smart charger's terminals to d ba3,link out d ups terminals to d ba3 too.I suggest u get an extension socket to b plugged at d back of d ups.Connect d charger to NEPA but d issue is how to know wen d ba3 is fully charged unless d smart charger is smart enough to possess ba3 full indicator,if not please get a mini volt meter sold at 400 naira to read d ba3's voltage section by turning d nob to left at 20v.During charging check at intervals till it full charge at 15V.Howeve,make sure u don't use d ba3 till death.Discharge it up to a safe level say 10.5V or 11V,den ccharge again.Since there is an external charger already I think u don't need to plug d ups to NEPA.DONT OVER LOAD D BA3 WITH PLENTY APPLIANCES.Now u can plug ur TV etc to d extension socket.

very true, but that cant be a problem, my mini audio amplifyer keeps over heating and always burns the sound ic, all i did was go to oshodi and bought a 12v small fan ,connected it to one big capacitor inside, i glued the small fan insid the amplifyer and covered ane screwed it. If i put on the audio amplifyer ane the fan start spinning and cooling the ic and transformer, u can do same if feel ur ups will overheat, just go to oshodi, get a sizable fan that will sit inside ur ups comfortably, conect the fan to the big capacitor and face the fan directly at the ups transformer , if u cant do it, look for any electrician in oshodi market, dem plenty, dem no go charge u pass 200naira unless dem see say u be novice, buy the fan ur self first

yahyamay:
Oga Ceejay,good job u have done.i contacted the Battery seller at oshodi and he only has 18ah battery,will it perform well just to power a 30 watt appliance?

dollarnaira:
Ceejay please is there a higher capacity charger for 100amp n 200amp deep cycle ba3s?If yes
please how much plus fone no of seller/address.Tanx sir

ceejay80s:
Its a small world

hotmolo:
pls sir, wen i buy d 20amps ba3 charger do i need to do any special settings? like where do i turn d knob to? secondly, from d pic u showed on how to connect in parallel, will d ups cable also be connected to d same terminal d battery charger is connected on the battery? i ask to avoid wrong connection.

ceejay80s:

if u have a 40ah and below battery , u wil set the knob to 40, if u have above 40-80-100ah, u will set the knob to 80-100ah and if u have 120ah and above battery, u set at 120ah.
But if u have a 40ah battery and u set the knob to 80-100ah, the charger will charge that 40ah faster.
Yes on ur second question
buy a 2.5mm flexible wire at oshodi, one yard is 200naira, buy in red and black color so that u dont mistakenly connect wrongly, if u connect it wrong ,that ups is gone but the smart charge will be ok because it has
reverse protection
and so on, get more info from the chargers manual

hotmolo:
thank you so much. i just checked my 2 old ups. 1 is 650vac while d second is mercury 220vac. is d 220vac ups completely useless for this setup?

ReLaTE:
Good job u are doing, keep it up.
I hv a used ups 650v blue gate (1 battery) and another used 1500v blue gate(2 batteries),I want something that can power my LCD TV,decoder, standing fan and about 4 energy bulbs for up to 6hrs after a full charge. My LCD is 90watts,Standing fan 70watts,decoder 25watts.
Pls suggest things to buy and how much it can cost in total.,about the UPS,which one will be good for the setup.

ceejay80s:


the 650va ups will do the job.
20amp smart charger= 7k
200ah battery= 30k
black and red wire and celotape = 300naira
if u have extra cash like 3 to 5k u can buy a brand new standing fan of 35watts and below to get more time and get an energy savings bulb of 15watts.
Please dont plug the industrial fans to it, big or small industrial fans like OX etc , should not be plug to the ups

ReLaTE:
Thanks a lot, where can one get these since am not in Lagos.

ceejay80s:

na for lagos me i sabi, i dont know of any other place

bishop4life:




You wrote 200ah battery 30k?please which type and brand?

ReLaTE:
Thanks a lot, where can one get these since am not in Lagos.

ceejay80s:

i dont know until i call to confirm which make is available. They are not brand new batteries

bishop4life:

OK bro. Thought it was new. But are they reliable?

pato405:
I was at Oshodi today and met with the guy: he was just too quiet. He however told me that he has only 65ah battery- which he showed me. I wasn't pleased with the battery because from my little knowledge of batteries, I think such Lead-Acid batteries might discharge fast. There was a warning inscription on the battery stating clearly " DO NOT CHARGE IN AN ENCLOSED SPACE" - Then I remembered I read something about such batteries releasing HIGHLY inflammable gases, so I declined buying it. Eventually, and to cut the long story short, I bought the 10watt fan from him. He bluntly refused selling it for 1,800, rather he sold it 2k.

Let me at this point state that I have been on a similar project before stumbling into this thread - and have, as a matter of fact, completed it today. I used a 150Watt inverter (I never knew a 650va UPS could be used as I had one that I actually wasn't using at home, and that would have saved me some cash). Anyway, I bought the 150watt inverter for 3k on Olx, and also bought a 100AH (used) from the same guy for 10k. I got a 10Amps charger for 9k from another guy who works at Alaba and a tiny (probably the smallest size change-over switch to enable me switch between charging and discharging with the charger and inverter respectively, because I hate having to tough the Aligator clips every now and then - fear That i might fumble with it and it goes boom - explosion..lol!). I had everything systematically and neatly arranged on a ply-wood and hung it near my PHCN power source

I have wired 6 numbers of 5watt bulb (two at my sitting room and 1 at every other room, kitchen and bath)...The thing chop almost 2k flexible wire sha!the wire spanned from the inverter to all lamp holders. All the lights DO NOT come on at the same time bacause I connected small N50 naira switches to each of them. I got Phillips 5watt energy bulbs 80naira each. Wires were ALL neatly tucked to avoid clumsy swirling of wired everywhere - which I hate with passion. I also have wired it to carry my lap-top and the 10 watt fan..... so far, so good..everything working perfectly. I will upload pictures soon.

Momoney77:


I just cant thank de op enough and all who have contributed so far. My question is
(1) is there any effects of charging de battery with low current. or effects on de charger, cause wr have been having steady low current in my own side here in Owerri.
(2) can anyone or de op show a sample of the ups to use, since some ups are better than others.and op made mention of ups that can indicate when de battery is down.
(3)i intend buying a new battery how can someone know original and fake batteries.
Sorry for de many question guys.

fixedhollies:
Mine is not so hard.... I have no engineering knowledge but iI came out with this.

One ipo4 battery
200watt inverter imported with 3k

It powers my energy saving bulb and listen to music with wover for 7hrs
