Why are my batteries all of a sudden leaking?

[CC glocker]

I'm very careful not to overfill them and use a funnel to do so. All of them have some degree of leakage. What gives?

How full are you filling them? Should only cover plates by 1/4" to a max of 1/2" barring this as batteries age they tend to start gassing a bit more than newer battery do during the charging process...

Probably about 3/4" above the plates. Maybe a bit more but about a 1/4" below the plastic tube. The batteries are early 2014's

Filled to high.... if they are like car battery there is a fill height ring inside to allow for expansion when on charge. Might want to take a little out if they are high.... otherwise if not too high then maybe getting overcharged??? Check output

Here's some battery info - http://www.cartsunlimited.net/Batter..._Tutorial.html

heavy use could cause bubbling when charging, causing water to be expelled out vent tops of all the batteries

Ok. So with all this in mind should I take all batts out and wash them off? I do use my cart pretty heavily at times so this could definitely be the problem.

wash off with baking soda and water ( baking soda neutralizes the acid )

Make sure that you only refill after a full charge cycle. Never refill before charging. The level goes up a lot during charging. Looks like they were slightly over filled. Clean them off good and they will be fine.
