(NAPSA)—For many motorists, the battery is a case of under hood, out of mind until they’re stranded by a dead battery, which can be inconvenient and even dangerous—but this doesn’t have to happen to you. Look for such signs that the battery is failing as the headlamps look dim at idle and brighten when you rev the engine or the starter groans and turns slowly, barely starting the car. Preserving the Battery While no battery lives forever, these tips can help keep yours cranking: *Keep it clean. Even on today’s sealed batteries, corrosion on the posts and terminals can compromise performance. Your service technician can clean it or you can. With the car off, loosen and remove the negative cable, then the red positive cable. Use a brasswire battery brush dipped in a paste of baking soda and water. Rinse thoroughly with water, preferably distilled. Reinstall the cables, positive first, and coat the terminals and clamps with a thin grease to prevent new corrosion. *Don’t run it down. Ensure that all lights and other electronics are turned off when the car isn’t being driven. If you do drain the battery and decide to jumpstart your car, carefully follow the instructions in your owner’s man- ual to avoid damaging your car as well as the running vehicle. Wear goggles and removeyourscarf, tie and jewelry. Today’s average car has 20 or more onboard computers. Connecting a positive cable to a negative terminal—or vice versa—can cause an expensive electrical short that could destroy one or more of the computers. Batteries wear out for many rea- sons,including age, extreme con- ditions, corrosion, frequent short trips and long periods of no use, but they rarely die overnight. Have your battery checked. Your service technician can perform a load test, which provides a snapshot of how muchlife is left in the battery. He or she may also check to ensure that your alternator is charging the battery properly. *Remove the battery if a vehicle is going to sit idle for more than 30 days.
