Battery Basics

September 14th, 2022 by

The car battery provides power to start a vehicle. It also powers lights, stereo, and other components. How long does a battery last? You may be surprised to know not for as long as you would think and not for as long as they used to. Batteries deteriorate over time and the lifespan is impacted by extreme temperatures, time, and vibration.  South Carolina’s heat and humidity are hard on a battery as is extreme cold. For many years, you could count on a battery to last for several years, but three years is about average now. Cars today have many more bells and whistles that make the battery work harder. Behavior can also impact your battery. If you leave the lights on or a device plugged into the USB port, it will also lead to reducing the life span of the battery.


We recommend that you have a battery test every two years. We provide this a complimentary service but do ask that you make an appointment. It takes about 15 minutes to perform the test.  If you do need a battery, we recommend replacing it with a Kia original equipment battery manufactured by Interstate that is specifically engineered for your vehicle. If you choose to purchase an aftermarket product, be sure to check the cold cranking AMPS (CCA) on your battery and be sure to purchase a battery with the same CCA.

If your car will not start, we recommend that you call Kia Roadside Assistance, at 800-333-4542. Jump-starting a vehicle can be dangerous and very costly unless you are sure that you know what you are doing. If you connect the cable to the wrong terminal, it can blow the high amp fuse that controls multiple items, and all power to the vehicle could be lost. In some cases, it could also damage computers. If you overcharge the battery, it can get hot enough to explode.

If you have any questions or would like to have a battery charge test, please contact us at 843.573.4995 or [email protected].
