It's truly amazing. The FEH uses the same Sanyo "D" cells that the 06-11 Honda Civic Hybrid uses. The FEH is one of the most reliable NiMH batteries ever made. The 09-11 HCH is the worst and the 06-08 is the second worst with outrageous failure rates. 09-11: 30% in the first 2-3 years. 06-08: 16% in the first 4-6 years.

Difference is the result of rear A/C cooling of the battery and very aggressive temperature management (battery temps typically run 80-90°F) where the HCH battery cooling is almost worse than no cooling at all - 132 hot spots and reliance on cabin air for cooling... and a very marginal cabin air cooling system.
