Corrosion on terminal

Yaris World, what causes this on the battery terminals? Sedan 2007. And what should I do?

In my experience the more miles you put on your car, the more battery terminal corrosion there is. You can largely prevent the corrosion by thoroughly greasing the terminals with wheel bearing grease.

It's a chemical reaction that occurs when dissimilar metals are in contact with each other. Disconnect battery, clean terminals and connectors, and coat with dielectric grease.

Just clean it very well, use baking soda and water to neutralize the acid. You can also use those felt protectors on the terminals, but as long as it isnt producing too much corrosion, a good clean every once in a while should be fine.

Battery terminal corrosion is usually caused by vapour released from the battery during operation as it reacts with the elements and attracts to electrically charged contacts.

Disconnect both terminals and clean using an alkaline solution to neutralise it. Use baking soda and water mixed as a paste and scrub with a brush. Dry and reattach the terminals to the battery posts.

Do not use grease. It is a fire hazard and has a propensity to migrate uncontrollably under high temperatures. Sometimes it will bleed and inhibit contact because it is an electrical insulator.

Coat the terminals with Würth battery protector spray or a similar product that will cauterise into a hard coating and will shield the terminals.

It would be prudent to also clean the ground contact to the chassis or transaxle case during the same procedure.

Good info Lux.... Grounds are the most important thing on modern cars.

I've used we'll bearing grease on battery terminals for 40 years. No fires. I've also tried the sprays And the felt rings. Not anywhere near as good as wheel bearing grease.

Yeah you're right, grease has worked fine for many years, but it's no longer a suitable all-inclusive, end-all solution to corrosion.

Many vehicles have a battery condition sensor integrated into one of the terminals and, for them, grease would not advisable.

I had a car come in with a burning smell and erratic fault lamps among other electrical gremlins. That battery sensor on the terminal suffered an internal malfunction from a manufacturer error, causing high impedence and arcing. I last measured the terminal's temperature at 226 degrees centigrade with my calibrated infrared pyrometer, and it was continuing to soar.

Had that car's terminals been coated with grease, it might have been on the news instead of my hoist.

I have this issue on my battery because the previous owner hackjob installed HIDs and it really puts hit on the electrical system. I have used baking soda to clean the terminals, but the blue/white fuzz comes back strong.

I can replace the battery easily, but will definitely use some sort of grease or the battery terminal protector when I do replace it

HID can't cause battery terminals to corrode. Infact, they consume anywhere between 35-55w depending on the kit, so they can't put any extra load on the electrical system.

I'm reading about this white and blue stuff coming out of the terminal is caused by lead acid batteries not being charged enough. And usually happen on the negative terminal.

Battery condition sensor should be sealed and waterproof. Grease wouldn't affect it. Usually is a box after the terminal, so you wouldn't grease over it, or spray all over it anyways.
