I have a 2019 R1250GS that seems to have developed a habit of killing batteries and I'm a bit puzzled.
Apart from an SAE connector to hook up a battery tender, no accessories are connected to the battery. With the battery tender not connected, the battery is dead after a few days to the point where it cannot be charged. Putting another battery in the bike and connecting it to the battery tender, the tender indicates that the battery is being charged, but after a few days the indicators on the tender show that the battery is barely alive.
Couple of things: Tender is good, as it charges and maintains other bikes without issues. I already went through two good batteries with the same symptoms. Judging by observing both points, I have eliminated at the moment the tender and batteries as the issue.
Any thoughts on best approach to diagnose the problem?
