Best Battery to be left in the truck?

[Fitsbain]

I'm in Pittsburgh, So it get cold, not Minnesota cold but still cold.

What would be the best battery tech to leave in the truck?

Going to make a mag mod. What it will be depends on the batteries.

Thanks

Any Lithium primaries really.

I currently have CR123 lights as vehicle lights.

CR123, I wouldn't recommend storing much in the way of rechargeable in a car, but if you want to store a rechargeable, Eneloop for AA, or lithium polymer/ion for larger sizes is going to be better.
