What is your battery's state of health?

     There are a few factors that determine battery life. Climate, individual driving habits, and creature comforts, such as GPS devices and DVD players, all play a factor in determining battery life. That is why it is important to have your battery tested regularly. It only takes a short amount of time and you will leave with peace of mind!

     Weather extremes can take a tremendous toll on your vehicle's battery. Compare the battery age with the average life expectancy of batteries across the country. Cosider these facts:

• Your battery loses about a third of its power when the temperature dips below freezing, and more than half of its power when the temperature falls below zero.
• A fully charged battery will not freeze until -76 F: however, a fully discharged battery could start to freeze at 32 F.
• If your region expects temperatures below 32 F or above 90 F -- make sure your battery is up to the task!
