Considering a Clarity to replace my wife's gas guzzling SUV. I have a Prius Prime I'm pretty happy with. It uses about 6kwh of a 8kwh battery, reserving room on both the top end and bottom end to purportedly increase battery longevity (ie, don't fully charge it, and reserve a good chunk for hybrid use at the bottom of the voltage range). I've looked for info about this WRT the Clarity, and haven't found any. Has anybody seen any details on how much of the advertised battery capacity the Clarity uses during a full discharge cycle? Is any reserved to extend battery life?
