I think the northerners and southerners are experiencing different problems with their car batteries that lead to the same result: a dead battery that doesn't work.

In the case of hot climates, it's well known that battery life is shorter than in cooler climates since heat accelerates the chemical activity within a battery, so they drain faster.

I believe the people in this thread trying to say I'm wrong are experiencing an altogether different problem where it's *so* cold that the liquid within the battery freezes and ruins the cells, rendering the battery inoperable for a totally different reason than what we experience in the South.

Since cold also slows down the chemical reactions inside a battery, I suppose people probably also experience difficulty starting their cars even when the battery isn't totally ruined, but again, that's not the same thing as having a totally dead battery whose energy has been completely spent more quickly in a consistently hot climate than one that works in a milder environment.

I stand corrected about the "not working well in the cold," although my original response is technically correct since cold temperatures *do* slow the chemical reactions within a battery, and thus prolong its life (if it doesn't get ruined by freezing).
