To answer the question, yes, car batteries can freeze in extremely cold conditions. However, it has to be brutally cold outside for that to happen. The typical car battery can withstand temperatures of 76 degrees below zero, which is unbearably cold.
How cold does it have to be for a car battery to freeze?
“A 100 percent fully charged battery will not freeze until approximately minus 76 degrees Fahrenheit. A fully discharged battery can freeze at or around 32 degrees,” Kimbrough said in a telephone interview.
Is a car battery still good if it freezes?

Can cold weather ruin a car battery?
Cold weather is especially hard on car batteries. According to AAA’s Automotive Research Center, at 0°F, a car’s battery loses about 60 percent of its strength and at 32°F it loses 35 percent. During cold temperatures starting an engine can take up to twice as much current as needed under normal conditions.

Does cold weather permanently damage batteries?
Chilly temps (below room temp, but above freezing) will temporarily reduce the amount of power available from a given battery charge, but won’t permanently hurt anything. … Extreme cold by itself — temperatures well below freezing — also can permanently damage a battery and/or the device’s screen.
Why would a car battery freeze?

Does the temperature of a battery affect how long it lasts?
Even though battery capacity at high temperatures is higher, battery life is shortened. Battery capacity is reduced by 50% at -22 degrees F – but battery LIFE increases by about 60%. Battery life is reduced at higher temperatures – for every 15 degrees F over 77, battery life is cut in half.
How often should I start my car to keep the battery charged in cold weather?
General Rule. Owners should start their car daily in zero-degree temperatures. Auto mechanics may advise starting a vehicle once a week to ensure continued battery life, but this is under the best circumstances.
Will a trickle charger keep a battery from freezing?
Trickle chargers can protect a battery from freezing, but choose the proper type. Old-fashioned designs are considered “dumb.” They don’t have the same control over the charge cycle as today’s advanced designs. In fact, dumb chargers can end up damaging the battery, which might lead to freezing conditions anyway.
