How Do Extreme Temperatures Affect Your Car's Battery Performance?

Most cars use lead acid batteries. This battery technology is good at delivering the high level of amps that an engine needs in order to get started. When the temperature drops to 32 degrees Fahrenheit, the battery's ability to deliver those amps decreases by 20 percent. At -22 degrees Fahrenheit, the battery's capacity drops by 50 percent.

Extreme heat is also bad news for car batteries. The heat evaporates some of the electrolyte. If you don't top it off, the capacity is permanently reduced. At 92 degrees Fahrenheit, capacity is half of what it is at 77 degrees Fahrenheit.
