can a new car battery freeze

[SanGage]

Yes, a new car battery can freeze, but it's highly dependent on its state of charge. A fully charged battery is extremely resistant to freezing, while a discharged one can freeze in moderately cold weather. The key factor is the electrolyte's specific gravity, which changes with the charge level. In simple terms, the less charge in the battery, the higher the water content in the electrolyte, and the easier it freezes.

A fully charged battery (12.6 volts or higher) has a freezing point around -80°F (-62°C). However, a severely discharged battery (around 12.0 volts) can start to freeze at temperatures as high as 20°F (-7°C). When the electrolyte freezes, it can expand and cause irreversible physical damage to the battery's internal plates and case, leading to a permanent loss of power and requiring replacement.

State of Charge	Voltage (Approx.)	Freezing Point (Approx.)
100%	12.6V+	-80°F (-62°C)
75%	12.4V	-55°F (-48°C)
50%	12.2V	-35°F (-37°C)
25%	12.0V	-10°F (-23°C)
Discharged	11.9V or less	20°F (-7°C)

To prevent this, especially during winter, keep your vehicle driven regularly. If you're storing a car, use a battery maintainer (trickle charger) to keep the charge level high. A frozen battery is often a sign that it was already weak or failing, as a healthy battery under normal use should maintain a sufficient charge to resist freezing.
