[Solved] Varta Blue Dynamic battery - How to get to the "traffic jam" (cell)?

Hello
I have a battery like this and maybe you know how to get to the cell and check the electrolyte and the condition inside

Unfortunately, it is glued / welded.

The manufacturer does not provide for such an action, the battery is about to fall, and you have to buy a new one. :P

But you can drill holes and fit your own plugs.



The drilling site should be as shown in the video, because the lid looks similar.
The downside is the small diameter, so it's hard to see anything.
And I would look for some better traffic jams than the ones in the video.
I gave small pressed plugs from the scooter battery.

Yes, these rechargeable batteries are sealed. It never happened to me that these varts required adding water. On the other hand, in varts, the active mass decreases after 3 years. And the lack of access to the battery is to hide the fact that the process of sinking the active mass begins from the first day. This is planned aging. If you absolutely want to look inside the cell and evaluate the electrolyte, you drill a 10-12mm hole and then seal it with hot glue. The plugs are not tight.

Unfortunately, the water evaporates and the battery is depleting. After 3-4 years, regardless of the brand, it oscillates at the minimum level. Unfortunately, it is after the warranty and the manufacturer explains it with our good, after all, we can hurt ourselves and extend the life of the battery. And so we are safe and after 5-6 years we have to buy a new one. In the event of a charging failure or a longer spin with a starter or charging with a high current rectifier, water loss can be significantly accelerated and even before the warranty expires, the problem would be solved by adding water. And this is only drilling, because the warranty does not cover water loss. Because it indicates incorrect operation or failure to charge the car.

For now, it is annual and holds electricity well
Yesterday I recharged it for a while and in the morning it had 12.78 (when I recharged it in November, it had 12.9 V

But after what time to do such a water quantity test?
Can you observe it. Eg weakened battery or something

I've never had to add water to a maintenance-free battery. The last time I put water into the battery was in the 90's. They are so tight that no water vapor can escape. I ignore the extreme cases when the battery is permanently boiled. Then the manufacturer does not recognize the complaint properly.

The tension won't tell you anything. Only the measurement of the electrolyte density and the measurement of the capacitance. A moment of charging the battery will not help, you need to charge it to 14.4V and measure the density of the electrolyte. If the battery is one year old and it is not a problem, what are you looking for in it?

You had to start writing from there. Definitely don't worry about anything now, the tension is great.

You probably have a 2 or 3 year warranty only after this time you can check yourself (if something is wrong with it), because if you do it earlier, you will lose the warranty. As long as you haven't already lost by trying to pry plastic.

Thanks guys for your help
