High temperatures can evaporate your battery’s vital liquids and weaken its charge. What’s more, hot temperatures can speed up the corrosion process. Corrosion will irreversibly damage the internal structure of the battery, and it’s even worse when your battery is “parched.”
Why do batteries fail more quickly in hot climates?
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 do you keep your car battery from dying in hot weather?
5 Ways to Help Avoid a Dead Car Battery During the Summer
- Keep it cool. Since heat drains a car’s battery, parking it in a cool or shaded spot can buy your battery extra time. …
- Increase your driving time. …
- Cut down on car battery drain. …
- Keep it clean. …
- Get a car battery charger.
How long will a car battery last in hot weather?
This evaporation increases corrosion to the battery plates which results in a reduced capacity, cranking power and lifespan of your car’s battery. Typically, a car battery has an average lifespan of 4 – 5 years, however, exposure to high heat for extended periods can considerably reduce this life expectancy!
Does heat reduce battery life?
Battery life reduces at higher temperatures
Battery capacity is reduced by 50% at -22 degrees F – but battery LIFE increases by about 60%. Battery life is reduced at higher temperatures – for every 15 degrees F over 77, battery life is cut in half.
How long can a car sit before the battery goes dead?
When stored properly out of the car in a secure place, a detached car battery has the chance to last up to six months. Just like any other car battery, it will need charging, but not as often as if it were attached. Giving the battery a charge around every 12 weeks is a good rule of thumb.
Can hot weather flatten car battery?
The simple answer is, yes. Hot weather can drain the life out of your car’s battery, When the temperature gets particularly high, the battery fluid can evaporate, meaning that damage can occur to the internal structure. Extreme heat can send your battery toward its dying days.
Can a car battery go dead from sitting?
Batteries can go completely dead if you leave your car parked for days.
Can heat affect car starting?
It is very common for heat to cause the starter motor and bad connection problems. Electricity doesn’t like heat. Heat creates high resistance in an electrical circuit. Most commonly this is a starter issue, but other parts of the primary circuit can have bad connections.

What temperature kills a car battery?
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!
