How much demineralized water should be added to the battery without scale?

Hello. I am in the 1996 Mazda 323F BA Z5, I have a TITANA 55041 12V 50Ah 220A battery. It has normal "cells" with twist off caps. Unfortunately, there is no preview of the electrolyte level on the housing. In each of the "cells" all plates are completely immersed in the electrolyte. When you unscrew the cap and look at the "cell" from above, you can see in the center of the cell two bent plates 2mm thick, running opposite to each other from the top (filler cap) towards the electrolyte. these laminae (their bent L-shaped ends) are not immersed in the electrolyte. QUESTION: Is this the limit of adding distilled water and should these plates be immersed in the electrolyte? Do the "cells" (the plugs have small holes in them) must be unscrewed when recharging the battery with a charger. Regards.

stick to this level, add water to the plates (L) and as for plugs when charging under the charger, they should be loosened cheers

the electrolyte level is determined by these L-shaped projections, the electrolyte is to coincide with its horizontal part, the plugs are vented and nowadays no battery has a hermetically sealed housing and you do not have to unscrew anything, just charge the battery and nothing will happen

Thank you very much for help.

And here, crap, another question.
How is the level not at the height of the base of the "L" plate, but 5-10 mm above them and the electrolyte covers them? It's about 10mm from the top to the cork. what effect this could have (good or bad: cry , and is it better to remove this excess to the bottom of the gills?

Leave . it will evaporate by itself over time.

The ground for the plates to be covered.

I have a similar situation, I opened my battery, unscrewed the plugs and it's dry there. I think it shouldn't be like that, I have a 300A battery, 6 cells. So I understand it like this, pour distilled water so that you can't see these 'harmonica'?

so

For years, I keep the electrolyte level about 10mm above the plates in the batteries in which I have access to the cells.

This is how I read your posts and I will tell you one thing ... You are close, but you do not fully understand how the plates work, acid in specific purposes .. And this one gentleman said that for several years he had a water level in the accumulator above the "harmonica" ... May it not pour too much. Because above, a few millimeters under the battery cover, there are clamps connecting individual plates, and they are metal, neutral electric, and when the water level is so high that it begins to flood both the two clamps connecting the poles of the positive and negative plates, a short circuit discharges the cell. To prevent water from splashing in the cell, water should be properly added only to the level of the plates. So that these albums can still be seen. But to be slightly flooded. This way, the cells and the battery in general are protected against unacceptable splashing.
I myself have searched many websites, and read a lot of works. And most of the people who have done this work have no idea what the relationship between cells, plates and acid (electrolyte) is. This is very important to good battery use. Not to mention that you shouldn't let it fully discharge. Better at the first signs of weakening of the battery, it should be recharged to maintain a constant voltage, and not to cause sulphation of the cells, which makes them lose their cumulative properties.

I allow myself to refresh the topic because I have a similar question. Namely, I bought a car and didn't change the battery before winter. Unfortunately, for the last 3 months the discharged battery was outside in the car, because I did not manage to detach the clamp because it "melted" with the battery pole. Only a few days ago I thought that I can unscrew the clamp from the cable (you have this reflex ). Unfortunately, I suspect that the battery is already finished, because charging twice all night didn't work - the car will crank the car once and that's it. Today I thought it might be the fault of the lack of electrolyte and hence my question in this thread.
I attach photos of the battery - maybe they will tell someone something, because I'm completely green in it.
Thanks in advance for any help.

In my opinion, do not play with this scrap anymore, just install a new battery, it will probably not be useful, only the trouble.

I am aware of this, but currently I do not have a financial burden of PLN 200 in my financial plans, so I need something temporary
To pour or not to pour?

And yet, top up with distilled water, charge and discharge several times, it may regain its parameters and it will stay.

Up to what level (based on the photos I have attached)?

10-15mm above the plates, funnel to these bridges and do not pay attention to any mythical short circuits mentioned above.

So these "bridges" are supposed to be above the water?

In those batteries that I had contact with, the electrolyte level was 10-15 mm above the plates, and in the Centers, these bridges were minimally flooded.

Bridges is another stupid idea, cells in normal batteries are insulated from each other with plastic, they cannot connect, pouring too much water will cause it to pour out through the cap while charging.

Everything is fine - it has been charging for 2 hours. But ... The charger while charging, immediately after connecting it showed about 3A, but after a while (about 10-15 minutes) it was 0A and it is like that all the time. But when I put my ear to the battery, I hear a characteristic "gurgling". So the question is: is this contraption at all?

Already charged! The problem is that the battery probably has a hundredth of its capacity and is scrapable.

The answer is no, maybe minimally. The noises mean that it is only suitable for scrap metal. As Col. wojtek1234321 waste of time.
Even if you manage to start the engine, it may fail at any moment.
I do not understand the statement that PLN 200 for a battery is a lot.
Think like this: you use a new one for at least a few years and one refueling (not LPG) is often over PLN 200 and you do not refuel once every few years, but probably more often?

The most likely phenomenon is:
Sulfated battery.

I suspect more that it discharged and froze. This is what it looks like. Desulphurization will do nothing here.

It froze for sure, it could have sulphated earlier when there was complete over-discharge and therefore sulphation. A sulphated battery has a low electrolyte density (when fully charged is 1.28 g / cm3, and sulphated is only 1.1 g / cm3, at a density of 1.15 g / cm3, sulfation in a discharged battery already occurs) and it freezes even more.
You are right, there is nothing to play with desulphurization, because, as I wrote earlier, it will not work anyway - scrap.

Sulphation is curable as much as possible, short circuits, plate corrosion, circuit tearing and mass drop are not treatable. What is wrong with the battery in this case, it would have to be first diagnosed. Measure the voltage with and without load, measure the density, see if all cells are "working" during charging, check the manufacturing date by code.

Thanks for so many replies. You can see that I can't save scrap metal anymore
One thing only makes me wonder, now, after about 2 hours, I looked at it again and it shows 3A on the charger!
What's the kaman?

Probably the lead sulfate is slowly coming off and the corpse begins to come to life. Charge it with a small current for a long time and passionately.

Akuś zombie or what?
