you said this:

100 degree F gasoline provides more power to the motor than 20 degree F gasoline.

Sorry but you are wrong there and in post 104:

I think you are mistaking the cause of the additional power. Modern cars have sensors that detects the temperature of the gasoline air mix. The car's computer analyzes different sensors to decide the optimal amount of fuel to inject into the motor. More fuel is injected when the air fuel mix temperature is low to aid combustion to provide the additional energy needed to heat all of the fuel air mix for additional production of hp to keep the motor running.

It's just not so. Sorry. I won't post about it again, this thread was about your batteries, as you said.
