Put a multimeter on the battery and watch the voltage when you try to crank it. Your battery could be able to charge up the the proper voltage but be unable to deliver the proper amperage required to start. Also make sure you have a really good ground directly on your engine block to the battery. I've seen Yamaha especially get picky about ground location and a simple piece of wire sort it out.

Free way to test is to use a jumper cable from a clean part of the engine to the battery negative. If the issue is gone you have confirmed the issue and its a low buck repair from there.
