By the way, I learned today in another Japanese forum: It even works with even less battery power! A 1.1-liter (eight-valve) engine was started in a small car using a 22 Ah motorcycle battery. A 1.0 triangular file was sent out with a 30 Ah battery.

THAT would really be something for ULF .

I also immediately thought of Ulf.

If you're thinking about me, here's my current battery story:
On Friday, Christel drove her Polo to the store, got back in, and tried to start it again, but instead of restarting the engine about 5 seconds later, the battery completely died, to the point where the starter motor didn't even make a clicking sound.
It was a full-size car battery designed for TDIs, with a capacity of 74Ah / 680A and terminal caps.
Despite a minimal quiescent current of around 10 mA, a functioning charging system, regular acid level checks, and topping up with distilled water. She only lived for a little over 6 years.
The acid densities immediately after production were all within the well-charged range (above 1.24 kg/l), but when subjected to a 0.16 Ohm test resistor, the terminal voltage drops to approximately 1V, and the battery emits a slight hissing sound. Therefore, the device has a cell connector or grid failure.
Since I had a battery of the same size from my Ibiza that was available as a (regularly recharged) backup, I installed it in the Polo before going to the store, and now the car is running again.

Based on my positive experiences with the 45Ah / 450A minibattery in my TDI Ibiza over the past ~3 years, I will purchase a similar unit. I will install it for a few months, drive with it (to identify any manufacturing defects during the warranty period), and then put it aside as a spare: http://www.battery-kutter.de/Blei-Akkus-oxid-1/Starterbatterien-PKW-LKW/Intact-Race-Power-RP50-12V-50Ah-520A-EN.html
The OEM battery installed in the ASZ Polo was a 570A Varta battery. The Ibiza has been using 450A batteries for years, and the Racepower battery is roughly in the middle of that range, so it should also be sufficient for the Polo.

Friday was likely the scheduled date for a battery test. The battery in my mother's car failed without any warning or indication, while she was refueling in Masuria, Poland. A replacement battery was not available in the small village, and the gas station owner spent half an hour on the phone trying to find one. The destination was only 17 km away, so they decided to take a taxi to the hotel that had been booked and paid for. The car was left with the gas station owner on his private property, and he promised to have it running again by Saturday afternoon at the latest. He almost kept his word, but the installation of the replacement battery had to wait until after the church service, before which he called urgently from the hotel and requested 211 PLN (Polish currency) for the taxi fare. "I requested that you pay 1300 Zloty upon pickup around 1 PM. This is approximately 50 EUR, which should be a reasonable price for a gasoline car battery. I don't know the exact original size or what was installed as a replacement." He didn't charge anything for his work, but according to my mother, he received a tip.
