Makes sense, replace one part and it transfers the weakness to the next weakest link. I looked at one battery in bits the other day, the guy doing it tested each cell and basically half failed most with the visual check (bulges or terminals corroded etc etc) so the entire pack was written off - some of the cells might be reused to keep something else going for a short time but when you get to that amount it's not worth the potential hassle factor.
