Ok so I have an 07 Outback non turbo 2.5i, well changing the headlight bulb I noticed the battery was bulging on the side and had leaked a little. That said I replaced it and now the car seems to idle a little higher. Before the change it sat and about 600rpm in drive stopped at a light now its seems to be setting at about 700rpm. Where should it be? I may just be crazy and not have paid that much attention.

It seems reasonable to me. That was a very unhappy battery. If it was taking more charging current, the alternator would require more power from the engine.

That's exactly where it should sit at idle. I wouldn't worry.

It's probably more related to the change in coolant temps than the battery. If the car sat long enough for the coolant temp to drop, that would raise the idle a little.

The ECM will relearn idle after a battery swap. It will probably go back to where it was after a few days.

The new battery provided ample amperage for everything to operate properly.

The car should be running at 700.
