Add the camera and thats probably more like 5 days. (Just a WAG)


Yep, and people want to run smaller batteries and think the stocker is too big


Also, even though ntron1 is editing his posts, I'll educate him.


1) Cold doesn't hurt batteries, it just makes their output weaker. A higher CCA battery is a) more fragile internally and b) more prone to heat damage. Add in the effects of cold on trying to crank the engine and you'll think the battery is crap. The battery is designed for the best percentage of the world (as it's the same damn battery in every one of them as they're shipped with the battery installed) so if you're in a crazy cold environment, you should be adjusting accordingly (block heaters, etc).


2) Heat kills batteries and people assume that the cold kills them because batteries tend to put out more power when hot (to a limit) and the engine is far easier to turn over, so the damaged battery isn't discovered until the winter when it's output is lower.


I'd love to deal with weather that wasn't so damn hot that it kills batteries in a couple years. People think CCA is the be-all-end-all stat for a car battery when it's not...
