He has recommended two brands for you already. People recommend what they have used or have experience with. I echo his sentiments that you may not get a genuine brand in Onitsha.

All my solar accessories were waybilled to my location from Lagos. Overcome your fear of waybill and contact the offices of the brand he suggested.

My neighbor has been using trailer truck ba3 for years now and no issues. It even last more than inverter ba3

good evening all, pls can dis device test acctual capacity of a battery.

Ok this is going to be long, but I should have dropped this post ages ago.

Late last year I was in the need of some new batteries as my gels had died prematurely and my experiment of using car batteries as backup was becoming spent.

Luckily for me, one of the top posters on the top alternative energy thread on NL posted that he had some used batteries for sale. A hoard of Quanta and Genus batteries. My instinct was to seal the deal on the Quantas as universal (including international) feedback on them has been positive, the only issue was the said poster felt that the Quantas were "average" and he could only vouch for the Genus.

I got to his house, as lovers of AE we gisted a bit. He brought out a device, I am almost certain it is better than the one you posted and tested the batteries for me. The Genus passed the test with flying colours while the Quantas performed poorly. He then thought me a very important lesson about "Resistance" which is one of the main parameters these devices use to tell you if a battery is good or not.

In simple terms for us here, Resistance is how well a battery holds a load without dropping voltage i.e. if I put 12 amps on a 200amp battery that has been fully charged and reads 13v.... roughly it should maintain 12.7-12.8v (12.7 is a full battery) for at least 30 mins or more. So long and short, the measure of voltage drop when load is applied. The Quantas failed miserably in this.

So I went ahead, against my instinct, and only got 2 of the Quantas and then 2 Genus as my host had been kind enough to educate me and give me the history of the batteries (the Genus were clearly newer and seemed to have also been charged regularly with Solar, and the Quantas looked abandoned). The price of the Genus was almost double the Quanta because he could vouch for them. In fact he was kind enough to still give me a discount on the Quantas further. Easily my best experience buying batteries.

Once I got home, for the first few days, my Walensehe was exclusively charging the "Average" Quantas individually. I had about 2 ammeters at that time so I was easily able to measure amps going into the battery and amps going out. Within 2 days I was messaging my host that the scrap Quantas were easily giving me 100amps individually and staying above 12.2v. I thanked him profusely.

After a week or 2 I decided to try my "genius" Genus batteies which I now wanted to sell seeing as the 2 Amarons are quite sufficient for my power needs. Once again I tetsted individually. I slapped 12amps of load on it and again it was doing perfect, voltage not even flickering and staying above 12.8v.

I felt so blessed.

Not up to 2 hours I heard a strange cry......my inverter was screaming .....I checked all my devices and I couldn't believe what I saw. Voltage on my Genus was saying 10.5....I checked load, still the same 12 amps and finally I checked my cumulative amps 16amps!! 16amps from a 200 amp battery that had passed all tests and I bought at a premium!! I was stunned.

I quickly tested the second one and the exact same behaviour was noticed. It cut off at around 17amps. I don't think any batterys have shocked me as badly as this did.

Now i did not inform my gracious host about this as it clearly was not his fault. These are the dangers of buying used batteries, they are a gamble, and you must always be ready to sell as scrap. But the lessons learned are tremendous.

I also blamed myself a bit and I would tell you why. You see I did not want to buy the brand Genus, as i had previous experience of it. A friend that I had introduced to the inverter world earlier bought 2 brand new batteries from the main distributor Simba and within 6 months he was calling in warranty and they replaced one for him. I put it down to the fact that the cheap inverter he got from Simba could have poorly charged it. A few months later the whole system became pointless. That was my experience of Genus and why I showed hesitation in buying them.

So to answer your question, no test is superior to a properly run load test.... and clearly a properly run load test for Hours and not a few seconds as these devices do!

4 months later, I am still enjoying my Quantas- even added solar and the Genus bank (now connected together in parallel) can now produce 60amps ( from 400 oh, lol) but only about 50 amps if put on that same load of 12 amps.

@ saint2ace

How far? Did you also buy the Genus or only the Quanta?

saint2ace:
Just a thought, is it that people can't phrase questions or responses properly, or we as Nigerians have this mentality that we know it all?

If we're sure of our facts and already have a mindset based on whatever notion, why come to a public forum to ask for enlightenment when one already has their mind made up.

Food for thought I guess.

Una well done oh

Reading ur write up is just like watching a movie with you as the main character, lucky you I must say cos u got the quanta, I so wanted to take the quanta cos like u said it was sold for dirt cheap but the charging algorithm for quanta discouraged me, as the users had a prag inverter which means absorb charge would hit 14.5v and quanta could only take 13.8v max.

Long story short 2pcs of Genus batteries connected in parallel couldn't do a 100w load for 1hr, so I counted my losses and sold as scrap, lost half my money I less than 4days, even crypto no bad reach that one..lolz

So lessons learnt, always stick to an established brand.

However, not all used battery scenerios are sad, as I bought 2pcs fullriver batteries from a nairalander in October for dirt cheap, bros wanted to swap out his old batteries of 2yrs for 2 brand new ones, so I went on a trip to gbagada, took the batteries off him for an amazing price (bros God bless you for ur good heart) and got home; charged the batteries full and dropped a load of 400w on the batteries. I was waiting for the inverter to sing the melodious tune it was known for, but Celine never sang, waited for almost 6hrs before Celine rose from her slumber.
Wow, I was impressed and funny as it sounds that's my main battery bank till date and it's still firing on all cylinders.

So the tales of used batteries are one of beauty and the beast, but for well established brands like fullriver, quanta, monbat and if u're lucky to get the original then Ritar, it's a worthwhile risk.

I hope these has been able to educate someone out there. Cheers...

Lol @ the watching a movie bit bro, I believe its a compliment.

I was certain you were the lucky person who came before me and scooped away most of the Quantas, he said the person was also a nairalander and was the person who even made him sell cheaper.

Funnily I use the Wanlesanhe to charge the Quanta's and it usually takes it to 14.2v with no issues noticed. I once tried to go higher with the charger in manual mode and instantly I stopped once I started smelling acid.

Even my solar is set to take it to 14.4 and not noticed any degradation yet.

I can't remember where i read that it's a good thing to take used LA batteries above their manufacturer voltage.... apparently helps to fight sulphation.

Good battery brands make sense, a word is enough for the wise on this.

I could sense that usual mentality from afar.

Well, I have tried

Be careful of those called lowest price battery,
Always remember that you get what you paid for.
Buy why so desperate to make money

You can save some bucks by going that route but you will most likely use that savings to pay for the troubles they bring later on. Bye.

hmmm lots off wiring .. looks like a mini bomb

Thanks for the recommendation Sir! Young shall grow logistics can be used to deliver quality items to him as we also send to some resellers down there at the East all things been equal ! Maximum Regards

Send your number, let's talk about he batteries

My neighbor has been using trailer truck ba3 for years now and no issues. It even last more than inverter ba3

IQUIT:
to me truck battery strong pass all this inverter battery, because our truck battery Don pass three years and he still fire from all angles.... Na only to dey top the acid be the matter because them dey leak out sometimes wey truck go bend.... Wetin I Don observe about car batteries be say na alternator dey mostly kill the battery, over charge and under charge, because you no go know until you say make you start truck the next day come see say battery no fit turn kick.

Another thing na vibration of the engines also they destroy the cells.

The only disadvantage na the acidic smell wey they come out when battery dey overcharge.


Oga ceejay80s, that 100amps car battery wey you give your mum still dey work well? Abi e Don die?

Can someone explain to me how surging works on fridges?

Like a 115w freezer or 120w freezer, what's the maximum surge in start up and how it's calculated in kwa
