OK, I just cleaned the rust and damage 2 days ago from a previous battery "leak" that happened about a year ago. As I was proudly showing off my work today, I noticed it "leaking" again. I did replace the previous battery last time. Good news I caught this one early. Now my question is what could be causing the battery to overcharge? Any suggestions to fix or help resolve this issue. I have a 2004 GMC Sierra 2500HD diesel. This has two batteries, the problem battery is the one on the passenger side near the fire wall. This was the same one last time.
