05 600RR with around 5000 miles. Just before the end of the season I went to start the bike... nothing and the clock resets. Figured the battery was dead so I plugged it into the charger. Next day I go to start it again, green light on the charger, no go and the clock resets again. Pop start it that time and ride around for about 50 miles. When I get home I check to see if it's any better, turn it off and go to start it again... nothing. I plug it back in one last time, green light, and still no go.

Please tell me it's just a dead battery and not something more serious.

Have your battery load tested. Just because it may check good for voltage does not mean it's good enough to crank the bike.

Thanks. Can I take it to any auto place or does it have to be motorcycle specific?

Also I dropped one of the terminal bolts deep into the battery tray. Does anybody know what size they are so I can pick up a couple?

Any auto parts store should have a load tester. The battery is a 190CCA battery if they ask.

Thanks Demented, do you happen to know about the bolts? I couldn't find them on the OEM parts list.

Thanks. Going to take the battery in today after work.

Took the battery in last night. The guy said it had about 85% charge but the cells were no good. Going to pick a new one up.

But now, the question is: is this just a case of the battery running out of life or could there be a more significant problem with the bike?

Almost fully charged but dead cells...ha.

You could have an issue with the rectifier and it over juiced the battery, or the battery just died. Easy to tell by checking the voltage output at the battery once you get a new one. Rev the bike to about 5,000RPM and check the voltage. Should be somewhere between 13v and 14v. If it's extremely high, or is showing battery voltage, it's bad (or an issue with the stator).

I don't get it.
Even one dead cell in our battery will have a voltage of 11.5, depending on which sell is bad. Cells would be a maximum of 9.2v, and nowhere near 85% of charge.

6 cells, 2.3v per cell, 13.8 total voltage for a stock, good, battery. I don't think who ever tested the battery knew what they were doing or talking about.

I think he was saying that the cells give a no load voltage that is ok but the internal resistance of the battery has increased or if you prefer energy density decreased to such a point that the effective cca of the battery has reduced so that the battery is crap, ie. the cells can be considered bad.
