9. Continual corrosion on the +post would indicate the need for a new battery

As lead acid batteries age the positive plates inside the unit tend to grown this can cause the post to be pushed up against the case top breaking the seal releasing acidic fumes which corrode the post and terminal.

The use of the felt pads and grease can give some temporary relief but if the + plate growth becomes excessive the top of the case may crack.
