AAA Nevada offers battery checks

With winter nearing, AAA Nevada is offering to test the batteries and charging systems of Carson City-area vehicles, regardless of whether owners belong to the auto club.

Motorists are placing increased demands on vehicle batteries and electrical systems by installing upgraded audio components, adding anti-theft devices, using cellular telephones, and plugging in laptop computers. And in Northern Nevada, cold and rapidly changing temperatures present an additional problem for car batteries, said Lisa Foster, AAA Nevada spokesperson.

To help keep electrical equipment functioning properly and reduce the chance of being stranded by battery failure, AAA Nevada recommends motorists pay more attention to battery selection and care.

"Simple maintenance can play a key role in maximizing the life of your battery," said Foster. "It is important to have your battery and charging system checked at least once each year. Early detection of a weak component can save time and money."

To underscore the company's emphasis on battery care, AAA Nevada subsidiary Auto Guardian recently kicked-off its Battery Service program. The program offers special AAA service trucks equipped to diagnose and correct specific battery problems.

Battery Service is a preventative program as well, with on-site battery events scheduled at AAA Nevada offices in Reno and the surrounding areas.

Battery care facts and tips from AAA Nevada:

- The major functions of the battery are to supply electrical current the starter motor requires to start the engine, provide power to electrical components and accessories when the vehicle's engine is not running and to supply power when the electrical system load exceeds charging system capability. The battery also acts as a voltage stabilizer.

- While hot weather is especially draining and damaging to a car battery, rapid temperature changes and cold weather are also cause for concern. Temperature changes stress certain components of batteries, and cold weather places an extra drain on the battery when starting the engine.

- Signs of a weak battery are slow engine cranking, dim headlights and illumination of the battery/charging system warning light on the dashboard.

- Before replacing a battery, have the battery, electrical and vehicle-charging system checked for problems.

- Keeping the battery case clean by wiping it down with a moist paper towel and mild detergent will help reduce any current drain caused by dirt or grime.

- If the battery has removable vent caps, check the electrolyte fluid level. It should be above the tops of the plates. If fluid is needed, add distilled water.

- Battery connections should be tight. Adjust loose fittings or replace fittings that have cracked.

- When working around automotive batteries, always wear proper eye protection and gloves, and never smoke or work near an open flame. Explosive hydrogen gas is present and may explode.

- Instructions for jump-starting a failed battery can be found in the vehicle owner's manual. However, jump-starting can be dangerous and motorists should seek professional assistance whenever possible.

- When selecting a new battery, always choose one that is of the same physical size as the original battery. And never install a battery with a rating lower than that recommended by the vehicle manufacturer.
