The one with the highest CCA rating you can find in the size you need for your vehicle.

Yes, that is how you know that the battery is "strong" enough to start your car in cold weather. A battery in warm weather may have enough amps to start the car fine, but in cold weather, it wouldn't be able to crank it fast enough. A car battery efficiency drops off the colder it gets.
The cold weather slows down the chemical reaction that goes on inside the battery.
Depends on your location.
Cranking the car or starting the car in cold weather can wear out a car battery. You can also wear out the battery by turning the starter over without fuel in the tank.
No, it does not loose power but when the engine is cold, it is just harder to turn over.
Take your battery to Napa and have them test the cold cranking amps, they'll tell you whether or not you need a new battery
Your car starter has nothing to do with cold weather starting so a factory standard starter would work just fine. However, solid fuel pressure and strong spark is the most important aspect in cold weather starting. Therefor, a high amperage battery will help a great deal.
Any good battery will work well.
no, its not possible. Actually it is possible for the battery to freeze, if the charge gets low enough it will freeze.
Yes. How old is the battery ? . Is it the correct battery for your car/truck Are the battery terminal connections loose or corroded ? Clean ,tighten Get the battery checked at a local garage ( load test )
One battery is probably just as good as another, but a battery that will last longer in cold weather is the AC Delco Super Heavy Duty battery. The more cranking amps a battery has the longer it is going to last when the car doesn't want to start right away.
