Automotive batteries more than two years old may be too weak to make it through the toughest winter weather and should be tested before cold weather arrives.

"A strong battery is the key to trouble-free winter driving," said Marshall L. Doney, vice president of AAA Automotive Services. "By checking your car's starting power now, you may be able to avoid inconvenient and possibly dangerous breakdowns when winter arrives."

Have a qualified service facility perform a battery load test. In this quick test, a technician attaches a special diagnostic machine to the battery to provide a clear measurement of the battery's condition.

Also, it is important to check the battery terminals and cable connectors. If corrosion is present, the connectors can be cleaned with a mix of baking soda and water. In addition to checking the battery, obtain a comprehensive pre-winter check-up for all vehicles that includes examination of the engine oil, radiator, tires (including the spare) and ignition system. Windshield wipers, brakes and exterior lights also should be inspected.

Fall is also a good time to test the vehicle's heating system to make sure no leaks or other problems have developed during the summer.

Because even the best maintained vehicles sometimes breakdown. Motorists should prepare a winter survival kit. Suggested items for the kit include: flashlight, blankets, booster cables, warning device (flares or reflective triangle), small bag of abrasive material (sand or cat litter), cloth towel or roll of paper towels, ice scraper and a small shovel.
