When that battery warning light on your dash panel is triggered, first you will need to turn off everything in your vehicle that uses electrical power, to conserve enough battery power to get home if possible, then once safely home you will need to check your Infiniti alternator. The battery warning light indicates that the charging system is not producing enough voltage to charge the battery. The vehicle cannot run for long without proper charging function from the Infiniti alternator, as the battery does not hold enough energy to sustain all the electrical functions and would be drained rather quickly. Your vehicle needs electrical power to run quite a few essential components such as, its computer, headlights, ignition coils and engine cooling fan to name just a few. Then there are the non-essential but convenient systems that we use every day that require electrical power, such as the radio, air conditioning fans, and power windows. All these systems drain power from the battery, which will cause no problem as long as the Infiniti alternator is doing its job well. The Infiniti alternator is capable of generating as much as 1500 volts of power, according to the demand placed on it. The Infiniti alternator seldom fails suddenly, usually its deterioration is gradual with warning signals to watch for, such as a dimming of lights, especially when items are used that have a high level of power demand, such as the rear defroster or air conditioner.
