Your Infiniti depends on a healthy battery to start itself, and to maintain the electrical system when the engine is switched off. A car battery has a limited life, and you’ll need a new car battery. Your Infiniti dealer in Ellisville, MO can install a new one for you. These are some of the signs that your battery could be failing. 
Signs You Need a New Car Battery From Your Infiniti Dealer
Worn Alternator
The alternator provides the electrical power your battery uses to start your car. Once your engine is running, the alternator starts to produce electricity. The power it produces is used to supply your car’s electrical systems and recharge your battery. An alternator is a long-lived component and should last at least eight years. Eventually, however, the alternator will show signs of aging.
A worn alternator will produce less electricity and eventually won’t produce enough power to sustain your car’s electrical demands. The lack of power will also affect your battery, as it will no longer completely recharge. Your battery will gradually get weaker and eventually die. Our technicians can test your alternator and install a new one if it’s wearing out.
Dim Lights
Dim headlights are usually a sign that they’re about to blow. They can also be a warning sign that your battery is failing. When your engine is off, your battery supplies the power for your dash lights, headlights, and other systems that require continuous power. A damaged battery may struggle to provide enough power, hence the dim lights.
You can test for a battery problem by noting the brightness of the lights under battery power and then switching on your engine. Your alternator provides the power once your engine is running. If the lights are brighter with the engine switched on, your battery is weak and will need replacement very soon.
You Have To Jump-Start Your Car
If you have to jump-start your car for the engine to start, your battery could be the problem. The problem could also be a damaged starter motor or a worn alternator. Jump-starting your car will show which of these components is causing the problem. If your car won’t start despite a jump-start, the starter solenoid or the starter motor is damaged.
Should your battery start and then die almost immediately, a worn alternator is the cause of the problem. Finally, if your car starts and your engine continues to run, your battery has worn out. When your engine is running, your alternator provides the power to keep your engine going. Our technicians will repair or replace the damaged components depending on the problem.
Don’t let a worn battery leave you stranded. Call our service department at Bommarito INFINITI, and we’ll ensure your battery is always working perfectly.
