You are very welcome.

Check the battery asap as if it has got to leaking point it could do a lot of damage to the board.

Not the best move but you should get away with it. A least it wasn't WD40!

Boards should generally only be cleaned with Isopropyl Alcohol or, where there has been leakage of a battery, vinegar (to neutralise the alkali) and then water. If water has been used then the board must be thoroughly dried using gentle heat from a radiator, hairdryer etc.

The problem with the old blue (NiCad) batteries is that as well as simply leaking, they could "gas out" releasing a corrosive alkaline gas with the ability to damage larger areas of the board!
As long as none of your components have green legs then you are probably ok.
