Well in my case, I already have a $550 spare battery and will swap it
with my perfectly good battery in about 8,000 miles. In effect, I have
two such batteries and will use one or the other.
When my original battery comes out, I plan to do the same modifications
to it. In short, it looks like I'll never have to pay the $4,500
replacement cost since I'll be doing my own work.
