Dealing with battery corrosion

Panic Button · Posted: Mon Jul 23, 2007 10:44 am Post subject: Dealing with battery corrosion

Has anyone any tips with dealing with removing corrosion residue from the contacts in battery compartments?

I've heard baking soda can help... Anyone got any other suggestions?

I use hydrogen peroxyde (form the drugstore) with a Qtip, it does a nice job when the damage is not too heavy.

The FAQ states

" Corroded battery contacts
This is the most common problem with handhelds. People leave the batteries in for years and
they leak, causing a blue "foam" to cover the contacts and plastic around them. This is a
relatively easy problem to fix, as long as it's not major. Most of the time, it's not even
necessary to take the unit apart, although if the problem is major, it will require to take the
unit apart to get at all the "foam".

Solution:
There are a cornucopia of things you can try!

-Use sandpaper on the contacts.

-Try using Hydrogen Peroxide on the battery contacts. If you can, dip the contacts into the
Hydrogen Peroxide. If not, pour it over the contacts and watch it go!

-Use a combination of baking soda and water. This works best using toothbrush to rub the
contacts.

-Use Coca-Cola. Seriously; it is very acidic, and reacts with the "foam," cleaning it off very
easily. Try it, but use some caution. The only problem with this method is that you have the
sticky residue left after doing it, so you'll need to clean it with water afterwards.

-Replace them if you can- NEVER through away an old game if it has parts you can use!
Keep the battery contacts with as much of the original wire as possible, keep the little wafer
shaped speakers, keep the rubber pads under the buttons. Having these parts lying around has
saved me several times. A lot of the battery contacts are interchangeable between games, esp
of the same manufacturer.

If the problem is really bad, the contact will probably break off. If this happens, there's
really not much you can do, unless you find another contact and solder it into the place of the
other one.

And, if the acid has gotten to the PC board, it's probably toast… "
