Hmm... strange.

I say buy a new battery... I'm thinking draining it down from having the parking lights on didn't do it any good. Now there's something wrong with it. :dontknow: Just a theory. I have no electrical knowledge to back this up.

 

I guess perhaps it could have been the trickle charger that was squeaking. I hadnt considered that before.

 

I've never heard a battery squeak. What kind of voltage does it read?

 

It read 12.59 with no load.
12.53 at curb idle with low beam
12.51 at curb idle with high beam
14.53 at 3K RPM with high beam.

Interestingly, it has fired up every time with the battery re-installed (with minimal charging since I took it off the charger when it made noise). Loose battery cables perhaps?

Also read downloaded users manual...which indicated the battery might leak gas when overcharged. So i guess that part of the mystery is solved.

 

I think your guess about the battery venting gas is correct.
I hear that once in a blue moon while having these types of batteries on a battery charger.

I think you can do either:

1) Charge the battery fully and have someone with a real, true-to-life, bona-fide, real McCoy motorcycle battery tester test it's condition.
Take action according to the result of the test.

2) Go out and buy a new one, fully charge it, and carry on.

 

Would be weird for the battery to die if he was able to ride it after the parking light episode. The alternator should have restored the lost energy in 75 miles, no?

 

No guarantee of that.
I've read information from the big motorcycle manufacturers warning about how the bike's alternator (and charging system) is fine for replacing what was just used from the battery in order to operate the electric starter motor, but not intended to act as a battery charger on a battery that's been substantially discharged.

This is why motorcycle manufacturers (and the motorcycle battery manufacturers) will insist that a battery not be put in the bike until it's fully charged.

 

Interesting. I've jumped a dead battery (from failed push starts) and haven't had problems out if it since. Been 2 weeks. It was dead enough that the LCD barely lit/dim lights and everything blank after a hitting the starter. Less than 30 mi later I cut the bike off at my destination and it started up fine some 30 min later and since.

 

Thanks for the info! I'll let you know how it turns out. Most likely I'll go with the new battery, and increased attention to the poorly designed parking light position.
