Baking Li-Ion batteries or Fahrenheit vs Centigrade

Another thread was talking about lithium ion batteries and overheating. This example wasn't meant to perform a test on the batteries but is what happens when you misread centigrade for Fahrenheit on your temperature chamber. You get two very distorted batteries and singed fingers.
 
One of the engineers Monday, misread the readout while testing two devices at 140 degrees. He didn't realize the error until he picked up the devices and scorched some finger tips. 140 C of course is 284 F. To widespread surprise, the units still worked and so did the batteries, though now they don't fit in the battery compartment very well. We also now know that the LCD gets very fuzzy at 284 F.

 Now you know what we mean by half baked designs.
