I have to weekly clean green corrosion from positive battery post on my Dodge pick-up. It statred even when the battery was new with new clamp bolts and cable/clamps scrubbed without any green residue missed. It just keeps coming back even though I've used proprietary cleaner and red sealer. Thanks

Your battery is leaking acid, thats the problem. replace the battery or get it warranteed.... if its leaking, its defective. remove the battery and use ammonia to clean under it, and the terminals, the ammonia will neutralize the acid. you need to fix it, before it destroys the hold downs and battery cables.

The copper cable is corroded. Replace the battery cable before it fails internally where you can't see it. It will turn brittle and maybe eat through the insulation and short-out.

How do i change the battery in a Peugeot 308


If you buy a new battery, most stores will help you replace it. you will need a ratchet set to remove the positive and negative ends of the terminal. you should remove the positive end first. and for the new one, add the negative end first.

The following assumes you have a top-post battery rather than screw-in battery terminals on the side of the battery.

The battery may be new, but if excess side torque was applied to the battery post when the clamps were installed, the seal around the post may be cracked. Battery acid and fumes leaking through the crack (even if it is microscopic) cause corrosion between the post and connector. Try removing the battery cable clamps and cleaning them and the posts with a battery terminal cleaner brush. If you see corrosion (yellow or yellow-white crust) on the battery post, you have a cracked seal. Wipe everything around the post with a disposable rag, then coat the plastic around the post with petroleum jelly (but not the post. This will reduce the flow of corrosive chemicals onto the connection.

Another possibility is that the battery cable clamps were not thoroughly cleaned when the battery was replaced, and now the corrosion from the old battery is causing problems.

If you are removing or installing terminal clamps on a post-type battery, you must avoid putting a bending force on the post. That means when you turn the wrench or socket on the clamp bolt, you must hold the battery clamp with your free hand and use it to exert a force in the opposite direction from the wrench to keep the post from "bending." Failing to cancel the sideways torque on the post, as I mentioned above, will crack the seal around the post. Since I began observing this precaution, I have run batteries for a full lifetime without any terminal corrosion problems.

Replacing battery 2003 ford windstar


Remove all guards in the way, unbolt the baterry hold down clamp, remove,then unbolt each battery terminal. replace battery with a fully charged battery of the same type. Clean the terminals good before installing back on the battery. Use thw terminal washers, usually green and red in color, red for the positive post and so on. Rough the posts, smear some battery grease on each post install washers, then battery posts themselves. Tighten both posts just to the point that they will not turn, don't overtighten them they may break, then you'll need new post ends.

You may not have needed to buy a new battery, depending on the age of the battery and the year of the vehicle. I have owned these mini-vans for over ten years now and one problem they seem to have is build up under the positive battery post. This is usually an oxide of some kind building up on the battery post from the battery acid and then isolating the battery cable end from making contact with the post. All I've ever had to do is clean the battery post and cable end and tighten it back up and it works fine. Battery post treated washers (red and green) help this as well as putting battery terminal grease on the cable end once installed to keep corrosion from building up again.

If you have a side post battery situation you'll need to take the battery cable off the battery and clean up the bolt with a wire brush and inside the battery connection with a small wire brush kind of like a bottle brush since the threads are not very big. After cleaning apply a "thin" coat of dielectric grease. This grease is conductive and will give a better contact and keep corrosion away.

I would bet your guess is the correct one,
cold weather is the killer of batteries,you need to chose one that has high cca's
Cold Cranking Amps, the hight the number the longer it will turn your engine over in the cold before dying.
the blue color around the battery post is corrosion,the best way to get rid of it is to pour hot water on it,
"not pepsi" like some think because it will just return.

1993 toyota previa. car starts when cold,but if i drive car 4 a while and turn it off it wont start until i let it sit 4 a couple of hours.


Corroded positive battery terminal. Clean both the terminal and the battery post and tighten clamp bolt. Don't just tighten bolts. There's a layer of corrosion that conducts when cold/damp and gets warm during starting and charging, dries out, and then won't conduct.

Changing positive post terminal battery cable


Cut off old terminal. Cut back insulation and check for discoloring or corrosion.

If corroded, clean with baking soda /water solution.

If discolored (burnt), cut back until you find shiny copper. If it's too far back, replace entire cable.

If not discoloring or corrosion, the cheapest solution is to go to any auto parts store or even auto section in wal mart and buy the type that uses two bolts to clamp down over new cable.

The BEST way would be to crimp a heavy duty terminal on there, and then shrink-wrap it to protect against the elements. However the tools could be expensive unless you can borrow.
