Blue-green crud on battery terminals...

What is that flaky stuff that grows on battery terminals? My inverter system at home, which uses golf-cart 6 volt batteries has ONE particular battery that grows this stuff at hyper speed It's the only one. The other are very clean.

Why does it happen only on the positive terminal?

More importantly, what's the best product to apply to the terminals to prevent or minimize the production of this stuff? Is it a good idea to put grease on the terminal, or not?

Thanks,

Gigi

You can use a bottle of coke to dissolve the acid off the terminals or baking soda and water mix will work also .

I was told if you glue a penny near the terminal it will corrode instead of the terminal, I have never tried this.

Yes, baking soda and water mix will do the work very EASY. Also, after clean it, cover the problematic terminal with thick grease and you will solve this problemo.

As an aerial lift mechanic I seen a lot of that crap on scissor lift batteries. One thing I found to help combat the problem is just never fill the cell the proper level! Just cover the plates with just enough water(1/4"-1/2"thats all. Far as cleaning them. With safety glasses on!I remove the one cables at a time,wire brush them on a bench grinder/wire wheel,coat with wheel bearing grease(post and cable)reinstall with SST nuts w/o lockwasher(the spilt seems to alow acid to creep in)tighten down and you're done. Cleaning with baking soda is the shinnizle. I like to mix up a thick slurry and pour over the batts and leave it there for added protection. Acid on the out side of the battery Will conduct current and kill a battery!Welcome my son, Welcome to the machine

The blue-green deposit is caused by an electrolytic reaction between the battery's terminal and the battery's post. The reaction can only occur in the presence of oxygen, so anything that will prevent air from reaching the connection will prevent this from occuring. Vaseline, or even motor oil, will prevent air from reaching the connection point. Also, if the connection is not fully tightened, air can penetrate the actual connection to cause this reaction.

If you do use baking soda and water to wash it off, be careful not to let it get into the battery or it will neutralize the acid.

After it's cleaned real good & once connected again, spray it with "Brake Quiet" from the Auto store. I've been using it on Battery terminals for Marine applications for years, and even in Salty watter conditions, it's still clean!
Not much to be said about everything else.
and one more thing "DON'T BE AFRAID!"

Thanks for the replies...
Amazing. And to think I was worried no one would reply to this topic.

While it's all cleaned up, I'll make sure it's tight tomorrow, and I'll put some grease on it. I won't find the Brake Quiet here, and forget about bringing stuff like that on airplanes now...
