Can cold weather ruin a car battery?

Cold weather causes car batteries to die for several reasons: Reduced capacity: At 32 degrees, battery capacity drops by 20 percent. At -22 degrees, capacity drop by 50 percent. This capacity reduction lowers the battery's power output, impeding its ability to start the car.

Does freezing damage a car battery?

“When it freezes it expands, and when it expands it pushes those plates together and often causes a short between the positive and negative plates.” That damage will mean you need a new car battery “in most cases, and if not immediately, then long term,” he said.
