What is the best thing to stop battery post corrosion ?

Answer 1

this may sound crazy but have done it for years and has always worked for me. depends if you have top or side posts. If you have top posts then put a little lithium grease on in it and then put a penny on wach terminal. For whatever reason this has worled for me. I had an old man tell me this once when he came into my shop so I tried it and damn if it didnt work. Side post I would just put plenty of lithium grease on it. Dont think a penny would stay on sideways.

Answer 2

The reason for battery terminal corrosion in the first place is a bad connection, cheap battery clamps, scared or marred battery posts or a combination of the two. Some of the battery clamps that come with vehicles these days are a disgrace. If your able to do it your self get rid of these cheap battery cable clamps or have it done. If your battery is new or being replaced get new clamps to match make sure your clams "FIT WELL" this is the time to start. If you have nothing else use a strip of light sand paper like 80 grit and clean off the battery terminals make them shine you do not want that gray look. Do the same to the inside of the battery clamps you will have to roll a piece of sand paper so it will fit inside the clamp. Place the newly cleaned clamps over the cleaned battery terminals twist them down and make them fit tight. Tighten clamp bolts. Use the electric grease or stop by the auto store and pick up a can of battery seal spray it is red in color I do not recall any trade name at the moment. Spray the battery terminals with clamps in place. If you do this right you will more then likely not have any corrosion the entire life of this battery. When you replace the battery do this over again..I have never seen a maintenance/mechanic shop go to this effort. It is wham bang you have a new battery installed without the cleaning and you will be back to corrosion problems in short order. I own ten vehicles and I do not have time to chase after corrosion on battery terminals. Do it right the first time. Oh yes the terminal spray is better then grease as it does not collect dirt.

Answer 3

A.) It's dielectric grease.

B.) Why would you want to put an insulator (Yes, grease is an insulator not a conductor.) on your battery post? Let's cover it all, that way we can get a voltage drop before we even get to the battery positive wire, yay!

C.) Go to any Auto Parts store, go near the batteries and buy the little "donuts" usually red and green that go over your battery posts.

Answer 4

A little grease smeared on the post and connection works pretty well. If you are having a lot of trouble with one post corroding the battery may have a small crack around the post.

Answer 5

Mc KAY battery terminal cleaner and protector. Comes in a aerosol can and should be at most auto supplies. Best thing I have found, been using it for several years. Much better than grease or other crap.

Answer 6

There are felt pads, one red and the other blue, that slip onto the posts, under the terminals. They are soaked with a corrosion deterent. Find them at nappa, or other auto supplies.

Answer 7

Keep it clean. Remove and clean the cables and battery terminals every fall. A grease called no-ox works very well.
No-ox is used on industrial battery installations.

Answer 8

i agree with dodgeman, a good heavy grease will prevent corrosion, be sure to clean the contacts and posts up real good first.

Answer 9

you do no longer could desire to do away with something. The nuts could be loosed without eliminating the powder. once you pass to place the hot battery in, use a baking soda combination and sparkling around the battery terminals.

Answer 10

clean off the battery post and put some grease on them.also you can get those round things(i cant remember what they call them)that goes on the battery post,they say they work pretty good.you can get them at auto zone,they dont cost very much.
