My R1250GS Kills Batteries

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.
