Eine Nacht eingestecktes VCDS -> Batterie 9V | Posts 16+

Hi.

I have a 70Ah battery installed.

Which brands/products would you recommend?

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Recommended batteries? That's basically like a fundamental discussion about the advantages and disadvantages of different manufacturers' 5W40 oil...

In the relevant forums, only people who are experiencing problems with a particular component tend to post. Consequently, you mostly read negative feedback. It might be worth investigating whether there are any batteries that seem to have a disproportionately high rate of issues.

A 70Ah battery block is available from virtually every manufacturer in a wide selection, provided that no unusual dimensions or terminal configurations are required. So far, I have not had any bad experiences with cheap batteries, except for one instance (a purchase made out of necessity at "real"; likely overstocked and improperly stored). I have purchased both from small parts dealers and from ATU. Their "Arktis" block with 44Ah is now also in its sixth year of use and has been used in three different vehicles.

Yes, I know.

But I'm overwhelmed; the engine block in my G3 TDI lasted for 11 years!!!
I probably pushed the Passat too hard (drained its battery) too many times.

It's still running, although the start on the weekend at 2:30 AM in some random forest parking lot was a bit "interesting"... but he made it through.

I have mostly had bad experiences with Centro batteries so far.
The rest, as "Hutfahrer" says, is largely unremarkable.

I can confirm that! They have a relatively short lifespan.

THE battery, and it's definitely "the," it MUST be feminine.

That annoying girl is now tagging along on all my short trips again.
As soon as it gets a little colder, she'll secretly abandon me... of course!

What does it matter if she starts acting up again; she will be replaced, meaning the battery .

Hello everyone,
Hi Martin!

Based on my experience, I would highly recommend the M3 from Moll.
Whoever tries to save too much money here will inevitably end up in a difficult situation and then ends up buying twice as much anyway (right, Spati? *laughing*)
For me, it offers the best value for money, is consistently a top performer in tests, and (at one point?) was an original equipment supplier for Audi.
In my case, or rather, in our cases, the batteries are subjected to extreme stress in all sorts of ways (short trips, auxiliary heating, long periods of inactivity, etc.), and they have consistently performed well over many years.
They always announced the impending failure of a device after more than 5 years of operation at least one year in advance, gradually, rather than abruptly (e.g., through sudden plate breakage).

Best regards from Munich!

Yes, I've also noticed the M3 positively... while browsing online.

"Announcements" I already had last winter... but I was able to ignore them by reloading .

...he meant that the cold start (of the engine) is gradually becoming noticeably more difficult, and not suddenly or immediately.
In my opinion, a battery is likely damaged if it requires more than approximately 2/100 to 3/100 of its rated capacity as "maintenance charge" when being charged at 13.8V. The higher the current required, the more likely it is that the battery will fail catastrophically.
Example: 70Ah, 2/100th = max. 140-210mA @20°C (!)

Ulf had also taken the time to write a beautiful piece in the spirit of the Enlightenment on this topic.

Best regards from Munich!

Given the history of this issue, even the most frugal driver would proactively replace the battery. However, the one in my 206 has so far been completely inconspicuous. I'm confident that it will still last through the upcoming winter, considering my daily driving habits and usage patterns.

I refuse, for the time being, to buy a new battery .

Okay, so it happened again yesterday: I let it run for 5 minutes (with the lights on), and then it wouldn't start.

I would call it a lack of capacity.
But then why does it start up without any problems otherwise?
For example, even this morning, after a damp and cold night?

Are the successful starts (which I didn't notice) so close to failure that even a slight decrease in temperature could mean the end?

I'm more concerned with understanding the reasoning, because I already know that I'll need a new one for the winter.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

If a new purchase is needed for the winter anyway, why not buy it now? The demand is still relatively low, and the selection should be large. If everyone suddenly rushes to the dealers with defective batteries, even common sizes might be unavailable, or you might have to take whatever model is currently in stock.

You could also – if you can find a suitable supplier – order a dry cell battery and then activate it yourself. This offers the invaluable advantage of getting an absolutely new battery without any unknown storage time, which you can then assemble yourself. I have had such good experiences with this even using very cheap batteries that I would do it again anytime. And especially when I could wait! This creates the opportunity to reserve a dry cell battery from your next order and receive it truly brand new upon delivery.

What about those small "magic boxes" that are supposed to prevent or significantly slow down sulfation?

OK.

The new battery is installed.
Twice it has already started up with that.

I'm still going to build my own AHK charging connector.

What was there?

org VW.

They offered a very reasonable price and said they would take a look at the old one to see if anything could be salvaged from it.

The new one is a banner.

Good decision . My last factory battery lasted exactly 3 years, so you've almost gotten lucky with yours.

The inconsistent performance of a battery can sometimes be due to a broken cell connector. The vibration during starting or driving can cause the crack to close momentarily, or it can open up again.
