My current battery is performing quite well and has another 12,000 miles of warranty coverage. Once this one is ready, I'll swap them; refurbish; and use my current battery in another project that will keep it in excellent conditioning.
Remember, this is the first model Prius sold in the USA, the 2001-2003 models. Feel free to use this to hammer skeptics who drag out the old "battery replacement cost."
