We are in the infancy stage of auto hybrid technology. Controlling discharge/charge cycles like Ford chose to do, may extend the HV battery for a longer period. Sounds good. Being more aggressive with the cycle, like depleting to 25%, and charging to 70%, would obviously increase MPG, but the price might be shortened HV battery life? So what is the dollar tradeoff in the long term? I don't know, but I'm sure everybody has an opinion. At least I hope everyone does. Hybrid owners seem to be opinionated, which is good.

I believe that when the day comes that our Traction batteries need replacing, aftermarket drop in battery advancements will make our present batteries seem archaic. Working in electronics all my life, I'm counting on it. Technology is wonderful. Embrace it, enjoy it, invest in it if you can Drive slowly, relax, get max MPG, and let the aggressive drivers go by. I enjoy laughing at them and their accelerated heart rates. Slow is good. $$$ savings on fuel is a worthwhile goal.
