At what temperature do AA batteries freeze?
According to Sanyo’s datasheet (PDF), basic AA Eneloops are only rated down to 0°C/32°F. Any colder than that and you can probably expect to see greatly reduced performance in medium and high-drain flashlights and devices. Lithium batteries, on the other hand, perform quite well when it’s cold out.
What temperature kills a car battery?
Drain #3: Freezing Temperatures
Cold weather slows everything down, especially the chemical reaction happening inside your car battery. In fact, at 32°F, a car’s battery loses about 35% of its strength. And at 0°F, it loses up to 60% of its strength—but your engine requires nearly twice as much power to start!
How hot can a battery get before it explodes?

Refrigerating charged batteries may help them hold their charge, but it’s best to use the batteries near room temperature to ensure they last as long as possible.
Does low temperature affect battery life?
Battery Resistance
Low temperatures increase the viscosity and tension of the electrolyte thus worsening the diffusion and movement of the lithium ions of the positive and negative electrodes. This increased battery resistance impacts the ability of the battery to operate properly.
