Hello, I would like to know how long the original battery was held by your boxers? My R1250RS is produced from 2019 (after a factory holiday – now 4 years old) and when starting it sounds like the battery is at the end… everything just before collapse but goes on. Several times starting (without driving a longer distance) is already difficult despite previous full charging with charger – there are error messages the sensors fail (due to undervoltage…v battery was always connected to the BMW charger (overboard socket) over winter and motorcycle was always in the garage… so had already had favorable conditions. Km stand 14000. Is this normal and I am only used to a longer battery life from the car? Thanks for your experience…
