Shortest battery life...ever
« on: July 19, 2014, 10:52:35 am »
I can't believe my C5 battery has failed already, 11 days, yup...  11. At least it held enough volts to run, just not enough amps to crank.
  Well, If it gets no worse than this...we've got it made.

Sorry to hear it.

I would suggest it may not have been prepared, charged properly out of the box.  Trickle charge for several hours, rest it, check voltage.

Battery prep is critical and is the cause of most old school battery failures.
They need to be filled with acid, left  to sit while the plates absorb the acid, level checked and topped off if needed and then charged. This is where the trouble starts. The charge should be no more than 1.5 amps. It is a 14 amp hour battery so you can do the math and see it takes SEVERAL hours to charge the battery. If you charge the battery too quickly you have ruined the battery. When I see batteries that fail quickly that is 95% the case, when someone will admit that they actually charged it for 1 hour at 6-10 amps like a larger battery. Also before you jump to conclusions make sure your charging system is operating properly.

For whatever it's worth, in my first thousand miles or so, I discovered a loose electrical connection (easily fixed once I found it). Unrelatedly, a few months later, I discovered that most of the 6 or so wires leading to my regulator-rectifier had been bent and snapped at the connector, resulting in no charge getting back to the battery. (This was a pain in the ass to find and tedious to fix, although not expensive or complicated; I just had to patch 6 pairs of wires together.)

You may well have a connection or charging fault. Many of these bikes come standard with those, but once you fix them they stay fixed.
