Cold weather is a lithium battery killer. And when I say cold can kill batteries, I mean it.

Without some form of heating, lithium-ion cells begin to struggle to deliver power once temperatures drop below 32°F (0°C). By the time temperatures hit 5°F (-15°C), the battery's capacity can be reduced by 30%-40%, depending on factors such as the battery's age and quality. This loss of capacity can cause devices relying on these batteries to malfunction.

The situation is even worse when it comes to charging.

Charging lithium-ion batteries at or below 32°F (0°C) can cause permanent damage due to a process called lithium plating. This occurs when lithium metal is deposited on the surface of the battery's anode instead of being properly absorbed into the material. At best, this process can kill the battery. At worst, it can cause short circuits or even fires.
