Is it best to "deep cycle" the hybrid battery, or should some effort be made through driving behavior to keep the charge up as much as possible at all times? Is the answer the same regardless of whether the emphasis is on fuel efficiency or battery life?

Thanks.

The NiMH battery in the Insight and Prius are longest lived with many very small discharges and charges (microcycles) - as opposed to deep cycles. In normal driving, you experience hundreds of these in a mile as your foot changes slightly on the accelerator pedal. The battery takes care of these slight changes in demand improving mpg a lot. In order to help longevity, the computer keeps the actual SOC of the battery between ~20 and 80% (someone please correct me if they aren't right)!

Deeper cycling (max to min) several times a day would shorten lifespan dramatically, but in real-life driving that never happens (unless you're drag-racing every day!).
