When to replace your car battery

Car batteries will typically last from around 3 to 5 years and time flies. Battery technology is so good that a dead battery seems to always take us by surprise because they cause so little trouble between installation and replacement. But, there are signs that your battery may be dying. Being aware of these signs may save you a call to OnStar for Roadside Assistance. 

• Your headlamps may be dimmer than they used to be
• Your vehicle may be slower to start up when turning the key/pressing the start button
• You may experience electrical issues with your radio, power windows, or your connected devices
• You’ve had to jump start your vehicle
• Your “Check Engine” light is on

A swollen battery case is a sure sign you need a new battery. It’s rare but it happens and can be dangerous. Let a professional change the battery.

According to AAA, there are three determining factors that impact a battery’s lifespan – time, heat, and vibration.

Time
The biggest sign of a battery problem is age. A battery can only withstand so many charge cycles. Short trips and leaving your car to idle also take a toll on batteries. 

If you have not used your car for an extended period, you might need a new battery if the car won’t start. You can charge it and roll the dice. Lots of people do. That’s your call but it will be at the expense of some peace of mind. Along the same line, if you have a lot of jump starts to get your car going you must consider the electronics and the effect all of this electronic surging may have on the On-Board Diagnostics computer. 

Not sure how old your battery is?  You can check for a manufactured date on the battery case.  You can also bring your vehicle to Huston Cadillac to have it tested. Click here to make an appointment. 

Heat
In hotter climates, the rate of battery degradation is higher.  Warm weather states typically see battery lifespans of around 3 years.  The heat causes the internal fluids to evaporate quicker.  Try and park your vehicle in a shaded spot or a garage when possible.  And, keeping the top of the battery clean and free of grime and corrosion can help.

Vibration
Driving on bumpy or rough roads is hard on your car’s battery.  Jostling can cause the hold-down clamps to loosen or break and can crack other parts of the battery. Just one more reason to avoid those potholes.  And while off roading is a fun adventure, it will eventually take a toll on your battery. 

When it comes to batteries, consider a proactive approach, especially if your vehicle’s battery is getting up there in age. This way, you are in control and not external factors that have a nasty way of leaving you waiting for roadside assistance.  If you have any questions, please contact our knowledgeable service team members at (866) 204-2409.
