My R1250GS Kills Batteries

[globalrider]

By the way, since someone brought this up on another forum...

I never believed in leaving a charger/maintainer connected 24/365 unless you tend to forget to check the battery voltage or have some accessory that draws current all the time.

The only time I use a charger/maintainer is during winter storage and even that is rare because I prefer to spot-charge my batteries and then disconnect them. When I see the battery voltage drop to 12.5V (no less), I'll reconnect the charger for a few hours. I just checked my 14 Ah AGM motorcycle battery that I disconnected 28 days ago and it is still sitting at 12.9V.

I had a similar problem....false start No start on my 2019gs...for me it wasn't the battery or the starter i replaced both.....it took about 6mo for the problem to be revealed and it was the One way starter Clutch bearing was failing and i only know this because it failed ....I am not saying this is the cause of your issue just that they are similar ....I had to do the repair myself and will post about it soon. I hope this is not your issue it involves removing and opening the engine!
