At almost all exposed ATMs I have seen these batteries, what kind of batteries are they?

In at least one instance, I have seen an installation not for ATM but for an office but with some 200 of these connected together.

These are the 2v 500ah to 2000ah cells.very durable but ultra heavy in weight.
They were the best b4 lithium came onto the scene. Being 2volts, you need 24 pieces for a 48v inverter, and @ 70k to 150k for 1 cell dep3nding on ah, then you realise these batteries are for men, not boys grin.

Georged1 is using the 2v 1500ah type. At C/10 rule for lead acid...you can see that you can put a 150amp load on these bad boys...no shaking, unlike your normal 12v 200ah battery, that u are limited to 20amps draw, to avoid irreversible damage

This was my first set of batteries in renewable energy. 2v 500ah. Has 6 to make 12v 500ah.
Did not know much then , used the batteries till they emptied and screamed, no solar then. Just nepa and gen . Gave me 5years.

If you have like 12nos of 2V 1500ah (you'll need 3 able bodied men to move one, lol) type especially by Gaston with inverter capable of pumping up to 100A and with commensurate load; rest assured of at least 4 years service life before issues of backup will arise grin

Interesting, I guess there is a reason why banks use this type of battery.

The place I am taking about runs several air conditioners and even lifts, now I understand why they went for these batteries.

I will investigate this option a bit more.

Be sure all those appliances are run on the battery though because it will require a room full of those batteries to be able to run those appliances on them.

Lithium has made them obsolete, a single 2v 1500ah cell is about 130kg, and 24 pieces of them would make a 48v 1500ah bank, weighing about 3tonnes, which has 72kwh, out of which you can use about 50% to 70% or 36kwh to 56kwh and this would cover a decent area in a room......
Meanwhile just 3 pieces out of the 4 pieces of 15kwh Lithium pack in the picture below in parallel weighing about 100kg per pack would give you similar energy.

these are single cell 2v batteries common with bank ups power rooms and telecoms mast installation.
i have the 2v 2000ah sonnenschein brand installed way back early 2020. it was a deal too good to resist as i got
them at a massive discount as part of 'project leftovers' and looking back, it's turning out to be one of my best
investments so far. unlike lithium, it's an 'install and forget' kind of set up. i don't have to worry about top balancing,
bottom balancing, bms, voltage run-away, etc. the battery bank just keeps delivering with little or no supervision.
and, i guess that's partly the reason why you see them being installed in those locations you mentioned.
you can choose to believe peeps like us who're quietly enjoying their installations without stress or believe those
so heavily invested in lithium that they would jump at every opportunity to discourage the use of lead acid.
obviously, such folks have an agenda. either they have stock they want to offload on you or they have friends who
are vendors they want to help in selling their wares. the choice is yours.
besides, if these batteries are as 'obsolete' as they want you to believe, why are banks, telecoms coys, major hotels
and multinational oil firms still holding on to them as if their life depends on them? need i say more? wink

This man, your defense of lead acid batteries over lithium is so pathetic and lame that it beggars belief. You do not want to move on from your old and obsolete technology, congratulations..

But please, stop trying to prove that lead acid is problem free because again, you have invested in a 48v 2000ah bank and a 40kw solar array so you can afford to discharge to 80% only.

Isn’t it pathetic that you know more than the white man who invented both battery chemistries. Isn’t it also lame that you know more than the white man who choose to use lithium batteries in laptops and electric cars with many of this electronics going 10-15 years on the same battery

Finally, who told u that lithium users battle with voltage and balancing? You are so stuck with old technology that you won’t do your research on how lithium works. Lithium batteries are coming with 5 year warranties and you are speaking English. Even for diy coupled cells, a proper bms and a reltec balancer and you are good for 5 years.

Please stop misleading people with your oversized bank and your oversized panel array. Not everyone can afford 10 million Naira arrays.

Allow people with small budgets to get lithium batteries that can stand the test of time and can get filled up quickly without 40kw arrays.

Enough of all the lead acid hype. All lithium users have had lead acid disappointments before we all ran to lithium.

You don hear person come here say e lithium battery don fail since 3 years wey people on this thread start to use am?

Wetin u wan hear again?

There we go again, yes as one of those in that category, I have a few lifepo4 cells for sale, it's only ignorance that can make anyone to believe I ranked lifepo4 cells better than lead acid just for marketing purpose.

again, my brother i think it bears repeating here that no one is saying lead acid is better than lithium.
op saw some 2v batteries and asked an innocent question (which really only needed a simple answer).
but, what did he get in return? instead of a simple answer, peeps jumped out calling 2v single
cells 'obsolete' and making all manner of suggestions as to how lithium has now overtaken lead acid.
a renewables newbie reading all that might be misled, so i was only trying to put the records straight.
