What temperature can batteries withstand?

The standard rating for batteries is at room temperature 25 degrees C (about 77 F). At approximately -22 degrees F (-30 C), battery Ah capacity drops to 50%. At freezing, capacity is reduced by 20%. Capacity is increased at higher temperatures – at 122 degrees F, battery capacity would be about 12% higher.

How do you start a cold battery?

“To start a car in freezing cold winter weather, start by shutting off any accessories, like the heater, radio and lights,” she said. Then, put the keys in the ignition, turn and hold the key for up to 10 seconds. If this doesn’t work, wait a minute or so before repeating the process.
