With a voltmeter, i got a reading of around 12.5ish. i rode it a short distance after that in second gear (cruising at 5k to make sure the battery charged) and when i got home, it was at 12.65. i checked the readings a couple times and it dropped to 12.62. I'll check it again tomorrow morning.
If left sitting, the battery slowly discharges, correct? I've poked around and found this tends to be the case, but i haven't actually tested it til now. Some people have said their bikes fired up after weeks of storage, but i guess it also depends on the condition of the battery.
Now it comes down to - what is an acceptable level of discharge while left sitting (i would say the battery is in good condition, but not new). I mean if the bike clearly doesn't start tomorrow morning, then i'll probably have a huge leak coming from somewhere.
