You can extend the batterys life but not that much. The best thing to do is to keep
it as fully charged you can but particals will still fall down to the
bottom and in time
this will shortcircuit it.

 SH> As for winter testing, we have Porsche up here right now testing Cayennes
 SH> but it really isn't very cold -- about -10 at night and 0 during the day.

Most of the manufactures are testing here in Sweden. Last night it was -38 up north.

 SH> But what they manufacture does not sell all that well here.:-)

Today nothing sell very well.

 SH> I hope Diesels have 12V batteries now.

They have but still, they are bigger then for gasoline.
