IMA battery replacement longevity
 

I've been reading about all of this on various internet sites and articles, but I would like some real world stories. For those of you who have had to replace your IMA battery packs, has that more or less fixed your problems with the cars or are they still causing problems? Have you had to replace them more than once or was one replacement good enough to solve the problem?

Not trying to beat a dead horse, just trying to get some real world experiences.

Thanks!
