Older Honda hybrid batteries (G1 Insight, HCH) die because they have insufficient cooling due to poor airflow and low fan duty cycle, and they operate in a wide SoC window instead of a narrow band.

The Panasonic cells Honda used are actually very good, they're just abused by the terrible BCM letting them work too hard and temperature fluctuations.
