We'll this is a lot of good information! Not that I understand it all. But my battery is not lasting like I thought it would. I posted in the battery life thread about that.
Note that the "Turbo" charger only charges at the higher rate until it hits 80% on the battery. It then "steps down" the charging rate back to the 'slower' rate, i.e. ~1A. At no point does the charger input enough power to cause the battery to absorb temperatures that it wouldn't normally see in day to day operation.
