Signs of a battery beginning to wear out are all very obvious to a vehicle owner. A car that does not start but only whines, clicks or makes no sound has a dead battery. Vehicles that have dimming lights and trouble starting coupled with effects known to be associated with dead batteries are also indicative of these problems.
Other common signs include the dash light for the battery coming on and damage to the battery under the hood. Another good indication that a battery is about to be an issue is the lifetime of the device, as automobile batteries are only designed to last up to three years. When this date is approaching, it is important that a car owner takes the initiative to proactively replace the energy source so as to avoid problems with failing power assets. It is possible for a battery to die faster in cases where corrosion or an incomplete seal around the engine block allow for premature or advanced weathering.Learn More
A bad battery can cause a car to lose power while driving if the alternator cannot keep up with the battery's charging needs. In older cars, a working alternator provides enough charge to power vehicle accessories. However, newer cars require more electrical power, which makes it difficult for alternators to deliver the required amount without assistance from batteries.Full Answer >
The common signs of a bad automotive alternator include a weak battery, dimmed headlights, an odd or burning smell and a whining or grinding noise coming from the front of the vehicle. Alternators are electromechanical devices that power the electrical requirements of the vehicle and charge automotive batteries while the engine is in operation.Full Answer >
There are two ways to recharge a battery with a bad alternator: jump starting it with another car or using a portable battery charger. Although it is possible to recharge a battery without the alternator, the battery will probably not be powerful enough to make it far without the alternator to cycle the charge.Full Answer >
Basic automatic headlights work through sensors that detect how much light is outside the vehicle. Most times, these sensors are located on the dash of the vehicle. The headlights turn on when the sensors detect a certain level of darkness.Full Answer >
