After reading about all the breaker issues, I've always wondered if it wouldn't make sense to just change the breaker at the same time you change out a battery. The breaker is certainly cheap enough.
You could always keep the old breaker as a spare if it was working ok when you removed it. I do this with my spark plugs, figuring if I ever cracked a plug while cleaning or doing maintenance I wouldn't be stuck without my ride.

Born in the deepest jungles of India, I was raised by a friendly bear, until I was kidnapped by a pack of unruly baboons who taught me the finer points of swing jazz, all the while being stalked by an incompetent python and an evil but mis-understood tiger... Ummm, wait a minute, that's the Jungle book, no I was raised just outside of St. Louis, But...in the deepest jungles of a middle class neighborhood .
