Hybrid batteries doing fine

There's good news in Jim Motavalli's Greentech report in the NY Times about NiMH batteries in hybrids. The batteries have gotten cheaper, and they have proven robust and long-lived. Toyota reports a tiny percentage of replacements - 350 packs out of hundreds of thousands of 2nd generation Priuses. Yellow Cab in Vancouver has about 100 hybrids, some having racked up as many as 300,000 miles. Yet only 3 or 4 have been replaced, according to the company's general manager.
