It depends on who is writing Batman at the time but I do recall a few instances where Superman has provided Batman with a sample of Kryptonite as a safeguard just in case he goes out of control and needs to be stopped. I think we can assume that Batman carries it around with him like a hot girl with a can of mace. Just in case.
In several instances Batman has had to fight a Kryptonian and in some of those circumstances he releases a hidden latch on his belt. Then the belt buckle opens to reveal a piece of Kryptonite inside. Again, this depends on the version and author.
However, with the exception of versions w/o Superman, Batman indisputably has a plan to kill Superman 'just in case'. THis can range from Kryptonite to modifying the Batmobile's headlights to be red sun lamps.
Superman gave Batman a kryptonite ring for safe-keeping and to use if Superman ever got out of control. It is kept in the Batcave.
Superman has stated that the only man he's afraid of is Batman, and with good reason.

However, without prep time, he loses, partially because he only carries kryptonite within metropolis.

Yes, the belt helps him get out of sticky situations.
Batman would win because he has kryptonite in his belt.
Assuming there's no kryptonite Batman, obviously
Superman gave a piece of kryptonite to Batman to study, even though Batman tried to kill Superman with it during the Tower of Babel story arc.
Superman has stated that the only man he's afraid of is Batman, and with good reason.
Their already has been a comic like that. Batman won using kryptonite gloves.
Because Batman and the DC villains are hogging all the kryptonite.
Batman had the upper hand on Superman & could have killed him with the kryptonite spear, until Superman convinces Batman to 'save Martha'.

Batman won their only fight, but through use of kryptonite. In the end, they came together for the greater good.

That is a matter of personal opinion, if you think about it, Superman is indestructible, but is vulnerable to kryptonite. Batman is also a good superhero but is vulnerable to normal pain
Technically superman is stronger but Batman knows superman's weakness so batman could use kryptonite against superman and defeat him. Nice spelling on the question by the way.Batman is better :P
