How do you unfreeze a car battery?

What do you do if your car battery is frozen? I live in northern Idaho and it gets downright cold. Sometimes my car's battery freezes as a result. What should I do?

Answer
“If your car battery is frozen, you’ll need to warm it up to thaw it out. Once you do, you’ll likely need to charge it with a car battery charger or get a jumpstart from another vehicle—that is, if the battery is still good.
To warm up your battery, you can try:
  • Opening the hood and letting the sun shine on it
  • Using a hair dryer
As a last resort, contact roadside assistance for help. Frozen batteries are often the result of batteries that were somewhat damaged or not fully charged to begin with, meaning yours may be beyond repair.
Urgently offers Jerry customers a modern roadside assistance membership. Along with traditional benefits, you get Uber-like tracking for the status of your service and the ability to contact your service provider directly.”
