Same issssues here, had H-D charge mine and tested fine, but stills gets pulled down for some reason. Will have them check this week, we have some warm weather moving in.

 

Also be aware that with a fuel injected bike you will need to have atleast 9.5 or so volts to even run the electronics for the bike to even run. so with the clock/radio/security it doesn't take long to run a battery down low enough to cause problems.

 

I am thinking its time for a warrenty check. Mine does not drain that quick, it will but nothing like what you are talking about.

 

I have on 07 Heritage and have to keep it on a Tender. Security system does drain it. My suggestion is a battery tender, or better yet, since the weather there is not much of an issue....RIDE MORE OFTEN, LOL!!!

 

I have an 09 ultra classic,,here in pa we just had a long cold spell,,single digets,,,I haven't looked at my bike in 2 months,, the weather warmed up a little today,,bike started right up, no probelems,,,you either have a dead cell or something,,,or you have a current drain,,,,

 

Have a competent dealer look at it. If no issues, keep it on a battery tender and you will be fine.

 

I would use a Battery Tender or a charger that you can put on @ 2amp setting that has Auto On Off..
