Hello, in advance: I myself have no driver’s license or idea of cars. So please be lenient if my question/idea is absolutely stupid. But the thought just doesn’t let me sleep… I learned earlier on on the TV that a very large proportion of ADAC inserts arise due to battery problems and can be solved with simple start-up help. Now I wonder if one could not carry a “replacement” battery for this? However, not for exchange, but for itself. So a battery with the right voltage etc., just with low charging capacity to make it easier. So a power bank for the car?! You usually also have a spare bike with you, so why not also such a thing? Or is there something that I don’t know about/see? Greetings.
