Dead battery this morning ? WTF ?

[f5fstop]

One of the top ten hits on the GM assistance center...dead batteries. Per my neighbor, who works for the Lexus assistance center in Auburn Hills, MI, bad batteries are in their top ten list too.
Normally, these happen in hot climates more than cold. In cold, the battery goes dead and if really dead a cell goes bad. In hot climates, the cells just go dead without losing the charge first as in a cold climate.
