how to tell a dying battery... ?

So my bike died on me a couple of times... once when i pulled in for a gas fillup (turned bike off, filled up and didn't start), another one when I accidentally stalled making a turn and (when i tried to start it back up - no luck) and a couple more. Jump started both times afterwards and things run with no issues for quite some time until the next failure...

So trying to figure out what's happening... The battery shows 13+ volts when i check voltage, and when I start the bike, it doesn't drop below 10... So how do I tell if there is a problem with the battery? Or should I be looking for a short somewhere?

Lastly, how long should the battery last in "on" position (with the lights on) without being started? Ran an experiment turning the bike on and not starting - after ~10 minutes it would not crank... trying to figure out if this is valid, or if it should be holding out longer?

Thanks!

Heh, thanks... well when it's dead - I know that it is :)

The question is how do I tell if this is a goner of there is something else causing the problems...

After the first time it died on me at the gas station, I jumped and recharged when I got home. After that - it served me quite well for an entire track day and then a few more weeks before it died on my once more... I'm trying to figure out if there is a battery problem, or something else in the system that causes the battery to die over long intervals...

I've just never saw this with cars - once a battery dies, recharging it rarely helps. It keeps dying on you almost immediately afterwards...

Just pull the battery and take it to get load tested. If it's bad, get another one. If it's still good, get a trickle charger. You should keep this bike on a trickle charger regardless of your batteries age.

Have you checked your voltage from the rectifier? You should have over 14v above 5k rpm.

Clean your battery terminals and your main ground cluster on the left side of the frame.

Thanks for all the good ideas folks.
Took it to advance autoparts for a test - came out with 89 CCA at fully charged. Recommended replacement.
Mystery solved.
