It's around freezing here at night these days with highs of 45 to 50 or so. I recently connected my 2016 Classic to a Battery Tender Jr., and all my engine starts (with tender disconnected just prior) are a little rough -- and yesterday it took 5-6 tries for it to crank over. Something doesn't seem right about this. I suppose it would help to start it while it's connected to the tender, which is fine, but still.... Thoughts?
