I have an 06' CBR600RR. My battery actually went bad, and when I had it tested they stated there was a bad cell.

Question is where canI get a new battery for my bike?
How much do they usually run?
Is CycleGear a good choice?
Any special considerations when buying a battery?

Also, I do not have my lil tool kit that suppose to come with the bike. What tools do you think is needed to carry with you on your bike?

Thanks the help, much appreciated.
