How Do Yall Keep Battery Connections Corrosion Free?

Auto parts stores sell a spray to keep em clean. Everytime I take a connection apart I spray them.

Some of my tractors, mowers, etc. seem worse than others. I had fits with a Super A today that had been converted to a 12 v system many years ago. Perhaps some charge at a higher voltage or amperage than others?

Not sure on that Jim. Hopefully someone can answer that for you.

i use copper coat antizies just brush over connection soak cable in baking soda water solition to clean it

I use sealed batteries. I dont seem to have any corrosion problems with those. But I do have a couple of regular batteries, that do get some corrosion on them, so I just clean them up and coat with grease.

Those little felt "do-nuts" that are meant to absorb what acid finds it's way out,
and a coating of grease seem to keep my terminals in good shape throughout the year.
At least a year or three before I need to clean them again.

Forgot the "doughnuts" earlier. They and the grease are my usual practice. The Super A yesterday had none, and I just reworked the connections last spring. Gremlins or TML I guess :?: :roll:

Had a battery guy tell me one time once they corrode it is almost impossible to stop it from returning. If the old battery corroded the new one will if you don't replace the cable ends. Done it for years now and vurtually never seem to have a problem. May just be a coincidence.

As long as you use some baking soda mixed in water to neutralize the acid, and make sure you've got all
the corrosion cleaned off the posts and connectors, they won't corrode again unless new acid leaks on them.
I'll dip the connectors and brush them several times until I see nothing bubbling when I dip it. Then clean some more.
I take a moist rag sprinkled with baking soda to clean the posts with. Then clean until I'm satisfied there's no acid left.
Use a little emory cloth to make everything bright. I always clean new battery posts too just to make sure they are acid free.

put more than a dab of grease on them.

after i clean the terminals and cable ends.. and make sur ethere is not corrosion in the cable itself, i put a thinn smear of grease ont he terminal, then coat the cable end.. then attach it snug.. then u regrease the terminal and cable ends.. I us ethe old stiff axle grease that comes in a lil ? 16oz tub.. i use an old chip-paintbrush to do it. that grease out of that tub is just for electrical connections...

i redo them every year.. and don't get any corrosion... no air or water can get to the lead that way..
