Your sources do not seem to apply directly to Prius hybrids. Some of the articles refer to all electric vehicles, in which charge states and cycles are much different from hybrid vehicles with ICE's. And, other links refer to AA battery storage prior to use, to extend their shelf life, which again, does not apply to the Prius.

In my opinion, Toyota was one of the pioneers in hybrid vehicle technology for passenger cars; and I trust their hybrid system computers to automatically optimize the traction battery charging parameters. By performing odd workarounds like discharging the traction battery before turning your Prius off, and unnecessarily driving without air conditioning for several miles in 118-degree heat, defeats Toyota's programming that is supposed to make the Prius driving experience as "normal" as possible, while saving fuel.

Also, try driving without air conditioning when the interior of your car is 140 degrees. That's just not going to happen here in Arizona, unless your air conditioner doesn't work. Sorry, but the air conditioner is the first thing I turn on after the ICE starts.

My opinions are based on about 140,000 miles of driving a Prius, daily. Sorry, but I trust my own first-hand experience more than some articles on the Internet that do not appear to directly apply to the Prius.

Like I said, I am only interested in the battery's chemistry in relationship to heat. I don't care about how the system charges the battery because I know it works and works well.

Well i know the Prius, never fully charge battery power anyway to prolong battery power. I think it's better to release, it more especially when the car is seated in the hot sun for the next 10 to 15 time while i am at work.

First of all, good job in choosing Prius. It's an excellent car. A battery will sooner or later die out. But to prolong the battery life, it's not advisable to have it fully charged.
