The question of why is a good one ... the answer is it's sheer cost! :)

The factory new battery is on the web for about $150.
I'm worried about the knockoffs which cost around $50 to $75.

BTW, I found some more references of successful rebuild DIYs which I'm
going through now as my biggest problem at the moment is finding the
replacement cells (later it will be fitting it all back together).
