Your battery could die at any point. If you properly maintained it, by keeping all the connections clean, keeping the battery box, and top flushed with baking soda an water, and by keeping the electolyte level above the lead plates using distilled water, it could last even longer.

But, even the best batteries die. Check with Insterstate Batteries. They seem to have one of the most comprehensive listings. McParts and Wally World usually do not even have a MB battery as a listed choice.
