Hi Jeff, I agree with William, but I also know how we try to help our customers. (Murphy's law is always in effect!) I would caution you in making any assessment of the batteries. You really can't tell how much damage there is.
My story involved a cracked post INSIDE the battery, un-viewable from the outside. This results in a high resistance connection, with melting/high temperature at the affected post. I had one that didn't show right away, but later the customer called with "a strange smell" coming from the bank. On inspection we discovered a large hole in the top/side of one of the batteries!
