The plastic case is cracked around the post allowing fumes to corrode the post. Buy some of those treated battery post washers and a can of battery terminal protector spray. Or, get a new battery.

I recently had this happen to my 2007 Ford Fusion it was under warranty so i took it to the dealer and they said it was caused from the battery leaking at the Post's,they replaced the battery and the positive cable and i have not had any other problems with it since.
No, it is the carbon
Outside the battery:The path for conventional current goes from the positive terminal (+, usually a red wire) to the negative terminal (−, usually a black wire).A wire's electrons flow from the negative (−) terminal to the positive (+) terminal.Since the current forms a continuous a loop in the same direction, the direction inside the battery is "backwards".Inside the battery:Conventional current flows from the negative (−) terminal to the positive (+) terminal.Positive ions flow from the negative (−) terminal to the positive (+) terminal.Negative ions flow from the positive(+) terminal to the negative (−) terminalConventional current assumes that all flowing charges are positive. It simplifies the situation because it hides the more complicated electrons, positive ions, and negative ions.
The battery post positive terminal is where you connect the positive cable. Connect the negative cable to anyplace on the engine or chassis. Connect positive first and remove it last.
No, the battery terminal should be able to handle as much electrical current as the vehicle should ever use, WITHOUT heating up. Clean or replace any battery terminal that is getting hot.
The battery terminal is loose at the positive post, or the cable wires are loose at the positive terminal. Remove the terminal, clean everything properly and then reassemble and tighten securely, and it will no longer spark. Your vehicle should start. A light spritz of WD-40 or the like will deter corrosion. It's cheaper than the little anti-corrosion terminal pads they sell at the auto parts stores, but feel free to grab a pair of them when you have a moment. Then when time permits, pull your terminals (positive gets pulled first and put back on last), clean them, and put on the pads before reassembly.
The Terminal Experiment was created in 1995-05.
The Terminal Experiment has 333 pages.
The ISBN of The Terminal Experiment is 0-06-105310-4.
One terminal is positive and the other terminal is negative. The positive terminal is slightly larger.
The positive + terminal is slightly larger.
Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
In a 2007 Boulevard S40 the positive terminal of a battery is located where the red terminal is. Another characteristic that separates it from the negative side is the width of the positive terminal.
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
A positive terminal will usually have red surrounding, or over it.
The positive end of a battery goes to the positive end of the terminal. In retro spec, the negative end of a battery goes to the negative end of the terminal.
in digs.the longer line(in height) represents the positive terminal.
Corrosion or a very loose connection at the positive terminal.
