Question: Battery terminal corrosion
Answer #1Bret Bodas from RepairPal Test Shop, September 07, 2009, 08:38Master
The battery probably has a small leak, possibly around the battery terminal. I would consider replacing the battery. Also, when you clean a battery, clean the entire battery with an acid neutralizer (baking soda) and remove both terminals and clean the posts and the cable ends.
