Corrosion on positive terminal

[cogsman]

Hi All,

When I disconnected the battery for the winter I found a greenish sludge/powder around the positive connector.

To be clear about how everything is connected:

- I have the main wiring spade against the terminal
- I have the positive lead from my Eklipes accessory terminal on top of that
- Then comes the bolt

No electrical issues at all with the bike, but never noticed this before. There isn't a lot of the green stuff, but I certainly don't want to create future issues.

Baking soda mixed with a little water to make a paste will clean it up. Or a can of coke

Here's what I do. Clean/wire brush all connections. Put them back together and spray with this stuff. Problem solved.  http://shop.advanceautoparts.com/p/crc-battery-terminal-protect-7.5-oz.-05046/7071027-P

What is it? It is the acid from the battery. Corrosion. The baking soda is the opposite Ph value, and will neutralize it.

Technically Baking soda is sodium carbonate. It's not a high pH to counteract the acid. Baking soda is in a class called a pH buffer. It tends to neutralize Ph whether it's low(acid) or high(caustic).

Great thank you! Will this continue to happen or is there something I can do to keep it from happening?

A little moisture can get into the connection which will cause a green/white corrosion. Some batterys seep a small amount of acid sometimes and a battery with a dirt build up on top will sometimes have corrosion problems and discharge also. I would do like the others say, clean it up and use a battery spray to keep it clean. Make sure and shine up your connections.

Could have been only a one time event, unless there is something like an acid leak that is causing it. I have seen car batterys that will continue to produce that green stuff. Clean tighten and spray, then see what happens.

Actually, I think it's sodium Bicarbonate. Not that it matters.
