The auto battery provides the power a car needs to turn the engine on. Batteries generally need to be replaced every three to four years, depending on your driving habits and environment. The unit will usually give off some telltale signs as it nears the end of its life span, so look for the following changes in your vehicle.

How to Tell You Need a New Auto Battery

1. Trouble Turning Over

A weak battery won't provide the engine with enough energy to start the vehicle as quickly or easily as it once did. It may take a few turns of the key or several cranks of the engine before the system starts. As the engine tries to power up, you might notice the dashboard lights dimming, a sign that the battery is using its waning energy reserves to keep the car functional.

2. Excessive Corrosion

Battery corrosion means that the acid inside the unit is reacting to the metal on the outside of it. Heavy corrosion diminishes the battery's voltage and life span, and it can begin to harm other components. Open the hood to locate the battery and look for a powdery or grainy buildup on the positive terminal. The corrosion will be white, blue, or green. Small amounts are normal and can usually be cleaned off, but frequent or excessive corrosion means the auto battery should be replaced.

3. Frequent Jumpstarts

A jumpstart gets the car running through a temporary connection to an outside power source. This is usually done by connecting two batteries with jumper cables, whether it involves two vehicles or one vehicle and a portable power supply. Starting the engine is what your auto battery is designed to do, so frequent jumpstarts mean the unit cannot deliver the necessary power and needs to be replaced.
