Re: replacement batteries

Cabela's has AGMs on sale right now for compelling prices. I picked up two group 24s there last week for under $150 each.

AGMs are better for my boat than SLAs because my tight battery storage location doesn't have room for a proper battery box.

Are you on shore power? A ground loop due to bonding issues on your boat or a neighboring boat is likely what is eating your zinc. A ground isolator is the correct way to fix that issue. Here is a good article on that subject:
