It will help, but a much better solution is to remove the battery cables, clean the connections and then use baking soda to neutralize the corrosion.
Pouring hot water on a car battery may temporarily help dissolve some of the corrosion, but it is not a recommended method as it can potentially damage the battery. It's best to use a mixture of baking soda and water to clean corrosion from a car battery.
A very thin smear of Copper Grease over the Battery terminal / Cable end will help pevent corrosion.
Don't fix it...replace it.
Clean it with a mixture of baking soda and water.
Though your alternator is constantly supplying power to your car while it is running, an incomplete circuit could cause your car to 'wind down.' Try pouring some coca-cola onto your battery cables where they connect to the battery to remove all that crud that collects there over time. It works, and looks pretty cool! I love science :D I hope that helps you out.
It was difficult taking the leads off the very old car battery; the buildup of corrosion was extreme.
If there is corrosion on the terminals then you will have a bad connection that will not transfer power from the battery to the starter. It is just like disconnecting the cable. Electrical current cannot flow properly through the corrosion,
My husband said it is caused by the vapor from the battery acid. It is the vapor of the battery acid leaking out of the battery, so the above answer is correct.
no it doesn't Corrosion on the top of a car battery can allow electrical flow from one post to the other which will drain the battery.
YES!!! Replace the car battery. The white corrosion seen on one of the battery terminals, is also inside the battery. The internals of a car battery contains lead plates , copper platres and sulphuric acid. During the (dis)charging process the sulphuric acid combines with the lead to form lead sulphate (The white corrosion). When sufficient of the white corrosion builds up inside the battery on the lead plate , it will eventually touch to copper plate. Whereupon the battery discharges and will not re-charge. The battery is //??@@#@!!! XX . So replace the battery. Sometimes, during the sulphuric acid /lead reaction hydrogen gas is liberated, if an electric spark occurs in the gas , there will be an explosion. So definitely change the battery!!!!!
corrosion of copper, from battery acid vapors, most likely.
A mixture of baking soda and water. Rinse with clean water.
