Acid may leak from the battery at the cable connections, resulting in corrosion on the battery cable ends and in the battery tray. A Leaking battery should be replaced and the cables thoroughly cleaned or replaced if necessary.Google+

Removed the battery cover and couldn't believe how much corrosion was surrounding the positive battery terminal!!! It was covering it enough that you could not see the terminal at all. Chipped the mess away and noticed a gap between the battery terminal (lead part) and the plastic casing of the battery. I am suspecting the battery is leaking. Unfortunately the corrosion was so bad it ate away most of the battery terminal. Negative terminal looked brand new.
since I had this piece of Crap car the battery was always leaking ! no wonder why people buy foreign cars ! this is the CORPORATE AMERICA'S WAY !

Bought new OEM battery needlessly. Then found the corrosion which had ruined the end that goes over the positive post. Cut corroded end of cable off, which shortened it, and replaced with generic end. Will replace entire cable when a reasonably priced cable is found. Chevy dealer wanted $146.00 for the cable alone which is unreasonable. With labor total expense most likely could have been over $300. Generic end cost about $6.00 and was done for free where I get most of my work done. Shortened cable had to be re-routed and plastic cover may not fit back over battery.

My "service airbag" light illuminated so I took the vehicle to my dealer. Apparently, my battery and the battery cable is corroded so I need a new battery, new battery cable, and a reset on the airbag system. Total cost $462. Regular warranty expired at 3 years or 36K miles, and extended warranty doesn't cover any of it because batteries/corrosion are excluded.

couldn't start my car this morning, it ended up being that my car battery head had corrosion on it that destroyed the connector.

Turned ignition and dashboard spazzed out a few times, needles looked like they were measuring an earthquake. The the car finally would not start at all after about 3 weeks and upon inspection, the pos cable was corroded and battery leaking acid. Replaced battery and car is fine now.
