Question about Varta Silver Dynamic H3

Hello,
To answer your question, we generally give a life span of 4 or 5 years to such a battery, which seems quite normal in the case of yours, and for your kind of vehicle.
Personally, mine gave out after a year (?), for no obvious reason...
But I know from experience that this can be the consequence of a sudden weakness of a lead dioxide bar, which results in a short-circuit in the battery, which amounts to an irreversible malfunction...
It should not be forgotten that these batteries are relatively delicate chemical-electrical organs and particularly sensitive to the treatments imposed on them. This means that, like us, they can mysteriously stop working after the first year, or even last well beyond five years, but this is rather rare...
Have a nice day!

For my part 6 years
