View Full Version : NES Satellite with battery corrosion

A little while ago I bought an NES Satellite. Opened it and found a ton of battery corrosion.
So I read on the internet that the thing to take out battery corrosion is water+vinegar.
I've scrubbed most of it off with q-tips.
Good idea to just let the rusted battery terminal soak in a bucket of the mixture? (I'm guessing I want to try to clean the rust as well?)
(I couldn't separate the PCB so I wrapped it in a plastic bag to keep it dry.)
I'm guessing it will be fine after letting it dry out?

I accidentally broke off the spring on the terminal connector. But I'd guess that would just need to be soldered back on later to fix it?

Battery acid requires a base to counteract it, not another acid. Baking soda and water is the correct mixture. Chemistry 101.

Chemistry 101... Alkaline batteries don't leak acid, they leak an alkali (hence the name) which is a base. ;)

Now for car battery corrosion you should use something like baking soda, but for alkaline C cells, unless it's really bad, you're probably safe just using whatever gets the corrosion off. Baking soda will likely scrub the crud off well enough, just don't expect it to be neutralizing it.

^^^ Excellent advice!

In addition to that, any rust that remains after an acid bath (i.e. vinegar) can be removed with steel wool or other abrasive.
