one of 4 batteries have excessive buildup on the positive post.

I checked the batteries this weekend for the first time since fall (4-5 months) and was surprised to find a large amount of buildup on the positive post of one (of 4) house batteries.

I dont have a battery monitor but I do have volt and amp meters wired in the panel so i keep a casual eye on the batteries. I check voltage and amperage upon arrival at the boat. I'm not fanatical about physically checking the batteries, I generally check water level 2 or 3 times a year.

The buildup has the consistency of a snow cone (granular and damp). Greenish in color. It was not a dry powder as you might find on a car battery.

Pics below.

What is this stuff? Is this a sign that something is wrong (either my maintenance or wiring)?

every other battery post and clamp were literally clean as a whistle.

Any signs of acid corrosion on batteries are signals that the battery is damaged and may need to be replaced soon.

Or do an internet search with the problem.

my opinion is that the post is not sealed within the top case of the battery and gasses are venting out.

I had this happening on my car battery on both (+/-) posts not long ago.
I had to replace the cable connectors as the originals were bent out of shape and not making a good connection with the post.
Not long after the new connectors were put on I had to replace the battery.

A solution of soda and water will clean it up. After cleaning remove and replace the battery. Check the battery cable connectors as the build up may have damaged them.
(This build up is a sign that the battery is leaking.)

thanks all.

So, any caveat in replacing one of 4 batteries? They are all over 5 yrs old, still seemingly all performing well.
