Battery Terminal Corrosion

[Langanobob]

It might just be one of the caps is not seated or is damaged. If it was my battery I壇 clean it up with baking soda, clean and tighten the terminals, spray it with battery terminal protectant oil and see what happens. With the cost of a quality battery. I壇 load test the battery before I arbitrarily replaced it.

I also switched to AGM batteries in my F250, end of terminal corrosion.

X2 plus:
Remove battery. With baking soda and water solution, paint and then rinse thoroughly anything the battery came in contact with. Fill a couple of smaller cups with solution and let the terminals soak for a bit in them.

Will dielectic grease work for preventing corrosion?

I think any grease would help, keep the vapours off the metal, but I'm just guessing that the special stuff has the chemicals that counteract the acid, contained within.

I've been told that it is recommended to change both batteries at once with the same kind or they won't charge properly.

I agree. If one battery is going bad, the alternator will overcharge both of them- producing lots of extra gas and shortening the life of the better one.

Well, that's not what I wanted to hear, but I'll look into that.

Almost have it clean. Unfortunately, I don't have the facilities to clean out the folds in the clamp.



Ran out of daylight, will have to finish tomorrow.

When cleaning around batteries, it’s prudent that one wear safety glasses, old clothes, and gloves. Stuff is nasty.

I change into different clothes (that don't have holes) to do any work on batteries - clothes I'm willing to put directly into the trash. And definitely full face safety shields.

As other have stated, that corrosion, particularly on one battery, is either a bad battery, or/and an over charging system. Feel the sides of the old battery and see if they are swelled at all. Should be perfectly flat. Don't forget to test the "good" battery. Often it is the root cause. Could be low and causing an over charge situation. I've seen batteries that have had the posts loosend by excessive twisting or just poor construction. Pay the extra and go to at least an agm. Definite test that charging system,, just a weak ground to an alternator and you will get high charge rates. Just know that all of us with dozens of batteries feel for ya.

In my experience having used a couple dozen batteries over the years terminal corrosion has always gone hand-in-hand with a failing or bad battery. This includes AGM batteries I would assume would be much less susceptible to leaks. Interesting, the over-charging speculation does seem to have merits, I always wondered the reason bad batteries always seem to be corroded.
