Do car batteries last less in hot weather

Summer heat is tougher on car batteries than winter’s chill. It may seem counterintuitive, but higher temperatures have a greater impact on the power-generating chemistry inside. And it’s not just about air temperature. Hot summer temps drive up the heat under the hood and accelerate the onset of battery failure.

How does cold weather affect a car battery?

And since the battery may already be suffering from reduced capacity due to cold temperatures, this can hasten the demise of an old battery. In the same way that cold temperatures are hard on car batteries, hot temperatures can also have a negative effect. In fact, hot temperatures lead directly to shorter battery life.

How does temperature affect the lifespan of an automotive battery?

It is no secret that automotive battery performance and lifespan are greatly affected by temperature. Most people believe cold weather is what kills the battery, but it is hot weather that shortens the lifespan of the battery. When the battery gets cold, the chemical reactions are slowed.

Why do car batteries die in the summer?

The Reason Car Batteries Die in the Summer. In fact, hot temperatures lead directly to shorter battery life. What that means is that a battery that is constantly operated at a balmy 77 degrees Fahrenheit will last about 50 percent longer than a battery that is constantly exposed to a temperature of about 92 degrees.

How to choose a car battery for hot weather?

This is one of the most important features when it comes to buying a car battery for hot weather. A higher Ah number means the battery can maintain a load for lengthy periods.
