Moin Gemeinde, my beloved elk (V70III, BJ2012), got a new battery in 2020. It should be a “Varta Sealed Lead Acid Start-Stop AGM 70 Ah 760 A (EN) E39”. From the basic data everything should fit. After about 6Mon. Start/Stop did not go any more. I did not investigate the reason, because this function bothers me anyway. Now, about 3 years later, the first warning messages in the combination (battery level low). How can this be? Is “Varta” not so high-valued anymore. ig? Which battery would have been the better whl? The original battery has held about 9 years…
