Your car's battery tends to be one of those things you just don't think about until one day, you turn the key in the ignition and hear the strained groans of the starter. Then the clicks... and then nothing. Car battery corrosion and a dead battery. Now you're the one groaning.
Contrary to popular belief, it's actually not usually cold weather that kills off your battery. Actually, excessive summer heat and overcharging, caused by a faulty component in the charging system (such as your regulator), are two of the main culprits that can damage a battery's internal workings. When this happens, the battery becomes weaker over time and tends to show its true colors when cold weather hits. Engine oil thickens up in the winter, making the engine harder to crank. So if your battery has slowly been draining all summer and is not in tip-top shape, you may be in for an unpleasant surprise when the cold weather comes.
So to help ward off problems with your battery before they happen, be sure to have your battery checked once a year, especially if it is more than two years old. ASE Certified Technicians at McKay Auto Repair, will perform a battery load test to determine the strength and condition of your battery to make sure your charging system is working properly. Also, always make sure to keep the top of your battery clean. Dirt is a conductor and can drain power. And finally, regularly check your battery's terminals for corrosion, and the cable connections to make sure they are tight. If you find corrosion, use a simple mixture of baking soda and water to clean it off.
