I recently noticed that I have what looks like mold on my battery. Is this a problem I should worry about? Also, sometimes my clock and radio shuts off from time to time and even at one point It wouldn't start. I took it to my mechanic and he told me that one of the battery terminals were loose and that he fixed it up for me.

Do you think I should just purchase a new batt?Name: photo 1.jpg Views: 2627 Size: 311.9 KB
