Car batteries Mt Wellington – What Are the Symptoms of Dead Cell on a Car Battery? A telltale sign that one or more cells is not producing sufficient amperage comes when the vehicle is reluctant to start, or “turn over,” to get the motor running. If the car starts and runs fine when the alternator is running. But if the car after being shut off for a time (like overnight), has a hard time starting, the likely cause is that the battery is dying; that is, the battery is not holding the charge it gets from the alternator.
The battery
A typical 12-volt car battery is composed of six cells that chemically produce voltage and amperage to start your car. When one or more of the cells fails, the battery is incapable of producing the needed amperage to start the vehicle to get you to work in the morning. A battery is charged continually by the alternator while the automobile is running. Cell failure is one of the most common types of battery failure.
If the car stops running
If the car stops running completely after you’ve started it and driven it for a while, it’s likely a sign that the battery is dead and not holding any of the charge it receives from the alternator. Even though the vehicle operates on the electricity provided by the alternator once it starts, that electricity runs first through the battery. This acts as a form of capacitor to regulate the amperage that goes to lights, cigarette lighters, inside dome lights, windshield wipers and electronics.
We can help
Too much amperage will burn out these electrical components and stop the car from running if it can’t channel the necessary amperage into the vehicle. If it can’t allow the charge to run through it, that’s usually a sign that the battery is dead or very close to it.
