Hello: Dead Battery

So, I've been trying to squeeze a few more rides in this year (as you know). Normally, morning temperatures hover around the freezing mark and day time highs reach into the 40s or low 50s (F). Yesterday, the high was only in the upper 30s. Shouldn't be any problem, unless you have a suspect battery (which I didn't know the NX possessed). So, I go to fire the NX up for the ride home and ... one or two cranks and then nothing. Crap. Back into the office to get a jump from a co-worker. Well, I must have touched the wrong cable clamp to the opposite battery terminal some time in the jumper cable connection process. Because, when I turned on the ignition key, there was nothing. No lights, nothing. I had to navigate to this blog to review the shop manual and determine where the fuse was located (just above the negative battery terminal, behind the right side panel). There's supposed to be a 15 amp fuse in there, by the way. My NX had a 20 amp (blown) fuse. Problem found. So, after a quick run down to a local service station (that's still a service station, not a convenience mart with fuel), I had a new 15 amp fuse (blade type) installed. After getting a jump from my wife's SUV, who was kind enough to come help me, I was on my way. I had no trouble on the ride home and the bike started right up after shutting it down (as I would expect). The NX spent the night on the Yuasa Hot Shot battery tender and was fully charged this morning. I opted not to ride because it was only in the mid-20s this morning and I didn't feel like being a guinea pig today.

So, now I'm left to wonder; do I have a battery going south? Or, do I have a stator that's not charging? I'm going to guess the former even though I was under the impression, from the previous owner, that the battery was relatively new. I'm going to have to review my NX file for receipts. You'd think that if the battery wasn't receiving a charge, it would have done this a while ago and that I would notice issues with dim lights, etc. Cold weather is supposed to reveal deficiencies with weak batteries so I'm not too surprised this is rearing its ugly head now. I suppose I have some things to check, over the weekend, don't I? I'll let you know what I find.
