Battery tie down corrosion

Hi,
Has anyone other than me had a problem with corrosion of the tie down on a battery? The terminals are fine. It's just the metal plate that holds the battery in place with bolts. The paint has corroded off. I clean it up and cover it with dielectric grease. I have to do this every 4 to 6 months or so, because the corrosion keeps coming back. I had the same problem with my 2004 Subaru Legacy, and had to replace the battery holder as a result.

Does anyone know why this is happening, and how to prevent it?

    It's possible your battery could be overcharging. Also some batteries react to the metals in the cable ends if they are too dissimilar in makeup.
