My car battery has lot of white powder on top?

I have a Toyota Corolla 2000. I changed nine years old battery last month ( it worked so well for me ), but since I got new battery I found a lot of white powder on battery top, I ask friends some told me it was normal, someone told me it was the sign of bad quality of battery and that white powder is going to damage my car. If someone can tell me who is right, I will very appreciate. Thanks.My car battery has lot of white powder on top?This white powder is corrosion of the lead battery terminals. Over time it makes a loose and bad connection.

This residue is corrosion as a result of sulfuric acid gassing that is released by the battery in heavy discharge and recharge. The sulfuric acid gas given off causes corrosion to

battery terminals.



You can clean it off with a stiff brush, and neutralize the acidic nature of this powder with a little %26quot;baking soda%26quot; from your kitchen / baking products.

Rinse it with clear water, because you don't want the solution to eat into the metal battery tray below.



Finally, spread a thin layer of vaseline or car grease on the terminals. This will prevent acidic vapors from affecting the terminals in the future.

Whatever it is, it's caused by a leaky battery.



It is either dried battery acid or it is corrosion caused by leaked battery acid. Either way, you need to clean the battery up, clean the terminals up. and then what I do is to spread baking soda on the top of the battery where the white powder used to be.



But if you have a lot of powder, don't do this. Baking soda and battery acid neutralize each other, but the result is hydrogen gas and heat. That's why it's important to clean the battery first. And that's also the reason why it's important not to do it if you are looking at a lot of leakage. I think the last thing you want to do is to start a flash fire . The chances are slim to none, but I don't want to hear about the guy who blew himself up on the advice of some Yahoo post.



But if it's anything like the normal amount of leakage, then periodic cleaning and applying baking soda will keep it from damaging other components like your battery cables.

Check to see if the terminals are tight. If you can move by hand, then remove %26amp; clean. Add a couple of tablespoons of baking soda to a quart of warm water. Place the terminals in the solution %26amp; allow to %26quot;boil%26quot; until boiling recedes. Rinse well with fresh water. Blow dry. They must be completely dry prior to installing. Wipe off the top of the battery %26amp; clean the posts. Apply grease the terminals %26amp; install.

If the posts are tight %26amp; the top of the battery is wet or wet around one of the posts, then it's leaking. Return it to the place of purchase %26amp; exchange.

It's not normal, but I don't think it will damage the car either. My car battery had this too. Sounds like leak of battery acid. Is it a dry cell battery? If it isn't, it maybe leaking water and battery acid. Just using some very hot or boiling water to rinse the white powder off and see how you go. If it returns, see your motor mechanic or good car battery retailer you trust.



Hope that helps, if it doesn't, forgive me, I'm a girl lol
everyone is correct. the white powder is a result of the sulfuric acid chemical reaction with moisture and contaminants. since this mixture is comprised mostly of acid, do not touch with skin or get in eyes. seek medical attention if contact occurs. baking soda will help neutralize the acid. kind of like the elementery school experiment with the volcano, vinigar and baking soda....same thing. it bubbles like crazy because it's disinfecting the acid. after the reaction stops, when it stops bubbling, take a garden hose or equivanent and wash it away, hopefully into a clean large container as to not pollute the environment or make a mess on your garage floor. with the new battery in, you can purchase special lubricant to help protect the terminals. you should be good to go for another 9 years
wash it off , it is a poor connection,and is acidic, check the terminals and clean them put on vaseline before tightening up finally.
I would not touch this...this can be highly explosive on impact and should not be disposed by an untrained professional.
that,s battery acid, don,t get any on your clothes or it will eat them up. clean the acid off with water and a brush.
it is corrosion.....sprinkle baking powder on it and watch it bubble...wire brush it and hose it off...GOOD AS NEW!
clean is with a tooth brush, this is normal for most cars though =]



hope this helps
clean it it off with a old tooth brush and new cables it cheep fix
