Frozen battery is a common phenomenon especially in weather conditions where the temperature drops up to -80 F or -26 C. But a frozen car battery does not mean a ruined car battery. That means you can fix it and use the battery again.

When the charge gets lower the mixture combination starts to get separate and the water freeze. It is basically called a frozen battery.
But a dead battery means a low-charged battery. It means the voltage of the battery is lower than the amount it needs to function. Usually, cars need 12 volts or more to properly function.
As frozen battery and dead battery means different things, the process of making it normal also differs. Please do not apply the methods of bringing a dead car battery to life in a frozen battery, it can be dangerous.
