Let's look at the scenarios and the characters.
Batman: An ordinary human. He may have access to conditioning regimens that ordinary individuals don't, but so does Captain America. He may spend all of his day working out, but so does Captain America. He also heavily relies on a full utility belt of gadgets. That means he's used to having gadgets for transportation, melee combat, distraction, etc. It's like the classic "ninja vs. samurai" fight, and Batman's the ninja. He has been trained by Lady Shiva and numerous other great masters of martial arts, meaning he may have ten to twenty forms under his belt.
Captain: Captain America is at worst a peak human, but looking at Marvel's ratings, he's a lot better. This means that he has conditioning from a cell of the US government with unlimited funds as well as a miraculous serum. He has taken hits that would cripple Batman. He thus has edges in the following areas: Fatigue resistance and endurance (remember that he literally does NOT get tired - the only upper limit is how much caloric capacity he has in him), reflexes, muscular power (particularly explosive muscular power), bone and muscle strength and mass (meaning Batman does less real damage per hit and is more exhausted), keenness of perception (meaning he can detect moments of weakness such as during stance shifts and react more quickly), and quickness of mind (in other words, his brain actually processes things faster in combat). He is a grand master of common American forms, including judo/wrestling and boxing/kickboxing, as well as anything else he may have picked up in the story arcs. He is used to having a shield, which means he may make a few mistakes with blocking. He also has decades of experience in context of the Avengers and World War II.
Simply comparing the two, we see that Batman is overpowered in a few key respects:
1) Raw physical capacity, in all of its forms
2) Reliance on gadgets (Cappy at best will be a little slow to block because of his shield, whereas Batman will be less prepared in almost every respect)
3) Arguably, experience
His only edge is his broader range of martial arts experience.
The battle is simply UFC-style ring combat. Captain America and Batman edge closer to each other, looking for weakness in stance or intention. Eventually, Captain America sees something Batman can't and rushes in. Batman may evade and get a hit, but Captain will undoubtedly salvage a punishing glancing blow. This will continue until Batman has been beaten down and surprised enough (since Captain America won't be getting harmed by any of this) to miss an essential clue and get put into a lock. That's all she wrote.
