Hardware [HELP] Balance Board suffered battery leak

[ACCA919]

It looks like this after I took some parts apart. Can I somehow make it usable again?

First thing to do is to neutralise the acid then inspect the damage.

Only the battery terminal was harmed. Also isn't the leaked liquid alkaline?

If you used alkaline batteries, yes. The electrolyte is potassium hydroxide, which reacts with CO2 to potassium carbonate (that are the white crystals on leaked alkaline cells).

General advise: No matter what chemicals you have there, you should remove them with a special cleaning fluid for electronics or rubbing alcohol/isopropyl alcohol. Remove the corrosion as good as possible. Let it dry completely before inserting new batteries.

If you have a multimeter, test the conductive paths on the corroded circuit board.

Thanks! If I don't have the the cleaning fluid, can I use vinegar? Also the batteries were removed with some cyan substance (like those on the battery compartment) on them, and I guess it's some copper compound.
