When you turn your key or push the start button, you expect your car to come to life right away. But what happens when it doesn’t? Many times, the problem is the battery. Your car’s battery is like its heartbeat—it gives the power needed to start your engine and keep important systems running. 

How Long Do Car Batteries Last? 

In Florida, most car batteries last about 3 to 5 years. The hot sun and high humidity can wear them out faster than in cooler states. That’s why drivers here need to keep a closer eye on their battery’s health. 

Warning Signs Your Battery May Be Failing 

Here are a few signs it might be time for a new one: 

• Slow Starts – If your car cranks slowly when starting, the battery may be weak. 
• Dim Lights – Headlights or interior lights that look dim could mean low battery power. 
• Dashboard Light – Many cars have a battery warning light that will turn on if there’s a problem. 
• Needing a Jump Often – If you’ve had to use jumper cables more than once, it’s time to get the battery tested. 
• Swollen or Corroded Battery – If you notice a swollen case or white, crusty buildup around the terminals, it’s a sign of trouble.

How to Make Your Battery Last Longer 

• Keep It Clean – Ask your technician to clean off corrosion during routine service. 
• Drive Regularly – Short trips or leaving your car sitting too long can drain the battery. 
• Have It Tested – A quick battery test at your auto shop can tell you if it’s still healthy.
