Normally most of us have corrosion which develops around our batteries terminals ,battery box etc but my is severe and develops very fast, after cleaning it thoroughly and coating the terminals using baking soda etc Multi meter shows a good charge 12 v. plus at the the bat terminals .. Always have this issue as most but this is really bad ??? Ideas.. Gene in MN
Battery terminal corrosion is traditional! A old timer mechanic told me years ago to use a little bearing grease or Vaseline to prevent battery terminal corrosion. HRP
The seals on the battery posts are broken, perhaps? If it's not overcharging, that's the most likely reason for it.
Thanks Jim Ya kind of what I thought, the battery case or at the terminals there is a leak' In 3 weeks the top of the battery ,the battery box are snow white with corrosion... Jim what could have cause the battery to crack, never been dropped ,is secure in its holder,no accidents, never an issue after first installing battery ??
I don't know what could cause the leak. I try to use side terminal batteries whenever I can, they don't seem to have nearly as much issue with corrosion as top post.
Batteries get shook around and the engine rocks on its mounts. Even if you don't have a broken mount the engine rocks. The cables need a little slack in 'em. Too tight and every time it shifts they get a little tug. Next you have modern manufacturing, things are just not as durable as they used to be.
If you want to stop battery post corrosion dead in its tracks, this is the stuff.... Amazon.com: Permatex 80019 Aviation Form-A-Gasket No. 3 Sealant, 4 oz. : Automotive The only real trick is all metal surfaces need to be spotlessly clean and make sure you cover all surfaces. Slather the sealer on liberally, the thicker the better. It usually takes more than one coat. If starting with used corroded battery terminals, I always replace the clamp bolt/nut with new, preferably stainless steel. I'll emphasize again, everything has to be spotlessly clean. Use a wire brush, utility knife, files to remove every trace of corrosion before coating, especially inside the clamp bolt hole. The finished terminal should be a dark maroon color and will be slightly sticky when dry (which will take a while...). Do all this and making sure the terminal is fully coated, you'll be rewarded with maintenance-free connections. If you do need to disconnect one or gouge it with jumper cables, touch it up immediately after reinstall/jump.
People take these for granted and don't give them any creedence whatsoever. Fact is, THEY WORK!!! https://tinyurl.com/2hmyceah I have used these on every vehicle I've owned since 1989 and have not had any corrosion issues.
I put them on every battery! Also when tightening the clamp bolt back it up with another wrench! If you let the post do it you can break the seal and fumes will come up under the terminal and start corrosion! I also use the commercial battery protector in an aresol can! It is also important to get the contact area clean and straight and tight! Bones
Whenever I check my oil, instead of wiping the stick with a rag those few drops land on the bat posts. never a problem.
I had a battery that leaked around the positive post. I added the felt battery washers and it was still a problem. Upon closer examination I could see the gap between the post and the case. I was pondering what type of glue, rtv, etc. I could use to seal it up that wouldnt take days to dry. I ended up using a hot glue gun of all things. I gooped it around the post area heavily and took the felt washer and stuck it in place. Never an issue again.
Battery corrosion Yup I think most of you touched on the issue Our batteries are leaking around the posts due to vibration,breaking the seal when tightening improperly , or as the engine shakes on its s mounts it breaks the seal at the battery terminals. Another point made earlier side post batteries sometimes have fewer issues with leaking. A interesting topic that we all have to deal with Thx much
That battery wasn't carried around with one of those straps that hooks over the posts by chance? I like Boneyard51's comment on using a second wrench when you tighten the clamp to keep from putting a twist on the post too. having long enough cables as Porknbeaner commented plus making sure the hold downs are in place and tight. I've never tried those anti corrosion rings but think I'll pick some up.
Corrosion Your point use two wrenches when tightening cable on post U get a check mark and a A for the day on that post gene
Any body ever seen the battery carrier that is just a short pice of pipe with an elbow on it….and you just put it on one terminal and lift? The battery will easy to move! The first time I saw a guy use one of these……I was horrified! Lol Bones
After ruining my battery tray and starting to ruin my inner fender on a 65 Coronet, I bought a Optima battery. Later I found the car was overcharging the battery. But I personally love Optimas- even the newer "Mexico" ones- I have had zero problems with them for 10 years- no liquid in them.
