A Florida Car Battery: Why Don’t They Last Long In the Sunshine State?

While Florida’s warm weather may seem nice at the beach, it’s not so kind to your car. It’s often assumed that colder weather would be the biggest threat to your battery’s lifespan, but in fact, the heat is worse. In cool climates, a car battery typically lasts 5 years or longer, but in hot climates, it’s only 3.

Many Floridians aren’t aware of the shortened lifespan and panic when their battery dies long before the 5-year mark. Below, we’ll cover how your car is impacted by excessive heat and the proactive steps you can take to help it last.

How the Heat Affects Your Car Battery in Gainesville, FL

The ideal temperature for a car battery to run at is 77- 80 degrees Fahrenheit. In Florida, it’s common to see highs in the 90s. But what actually happens when it gets too hot? 

In commonly used lead-acid batteries, the liquid within evaporates, causing sulfation. This means that harmful lead-sulfate crystals form. High temperatures can also make the battery’s plates buckle, which occurs when your battery swells or warps.

If your battery is located in the back of your vehicle, like in a Cadillac, it’s less exposed to the sun and will have a longer lifespan.

How Old is Your Car Battery?

Each car battery has a specific date code for determining its age. Depending on the brand and type, the date code may contain arrangements of letters. To understand your battery’s code, you can look up the standard format for the brand.

Proactive Tips

While we can’t change the weather, there are a few ways to slow the wear. First, keeping up with maintenance appointments will ensure that your mechanic will check for corrosion and clean it off before it becomes a problem. Another tip is to park in the shade or in a garage to avoid the sun.

When Should I Replace My Car Battery?

With the shortened battery life, it’s important to stay aware of signs that your battery is suffering or ready to be replaced. The obvious sign that a battery has died is the inability to start your car. However, there are a few other signs that can occur before it gets to that point. For example, you may hear cracking or clicking sounds, or your vehicle may be slow to start. However, it’s common for batteries to die in Florida without prior warning. Your car can start on your way to the grocery store, but easily fail to start on your way home.
